3. Answer the following questions in a paragraph of about 150 words each: (Text Book Page No. 31)

Question a.
Compare and contrast the main characters, Aksionov and Makar Semyonich in the story.
Answer:
The protagonist – Aksionov – prison – twenty-six years – nobody believes – works hard in prison – lives a simple life – helps other prisoners – make a real convict – accepts the murder at the end – governor came – questioned all the prisoners – someone dug the hole – Aksionov – no words Makar – told the truth – Aksionov surprised – forgive him – rather revenge.

The protagonist Aksionov is sentenced to prison for twenty-six years for a crime he did not commit. He is unable to defend himself. Nobody believes him, not even his wife. He works hard in prison, buys books with the money he earns, reads, and lives a simple life. Instead of focusing on his grief, he helps others and earns their respect in jail. As far as the character of Makar Semyonich is considered, he is the real convict of the story but it is revealed only at the end of the story.

Somehow he accepted the murder only after seeing the noble personality of Ivan Dmitrich Aksionov. Makar felt guilty for murdering the merchant and he begs for forgiveness. Though Aksionov came to know that Makar is the real culprit, he did not try to reveal the truth. It was so evident that one day the Governor came and questioned all the prisoners to find out who had dug the hole.

Aksionov did not say even a word about Makar thinking why he should ruin his life. When Makar Semyonich told him that it was he who killed the merchant and hid the knife in Aksionov’s bag, he was rather surprised and not want to take revenge on him. Thus “God sees the truth but waits”, Leo Tolstoy highlights the theme of guilt, faith, forgiveness, conflict, freedom, and acceptance by comparing the characters Ivan Dmitrich Aksionov and Makar Semyonich.

Question b.
How did Aksionov react when his wife suspected him?
Answer:
Aksionov – wealthy merchant – Vladimir – happy family – a joyful person – living in his own style – wife loved – bad dreams – stopped from going to the fair – Aksionov – met a merchant – murder happened – Aksionov in jail – wife suspected — unable to tolerate – the only god save his life.

Ivan Dmitrich Aksionov is a wealthy merchant from Vladimir. He possesses kinds of wealth, family, and children which made him happy and thankful for his lifestyle. Aksionov is a joyful person, living in his own dream. Aksiono’s wife also loved him very much. That is why, she stopped her husband Aksionov from going to the fair, telling him that she had bad dreams about him.

According to her dream if he left for the fair he would return his home with grey hair. The dream may be a symbol for his wife to think that there is something going to happen. On the other hand, Aksionov did not give importance to his wife’s dream rather he would like to live in reality. When she went to meet Aksionov in jail, he did not know how to tackle the situation. Aksionov couldn’t tolerate it when his wife asked what had happened to him.

His wife told him that she had sent a petition to the czar, but it had not been accepted. He was not able to tolerate when his wife suspected him and Aksionov said “so you, too suspect me!”. He began to weep and hiding his face in his hands. Unable to tolerate the situation, he said to himself, “It seems that only God can know the truth; it is to Him alone we must appeal and from Him alone expect mercy”.

Question c.
Describe the life of Aksionov in prison.
Answer:
Aksionov – to be flagged -sent to mines – driven to Siberia – twenty-six years – became white hair – often prayed – earned a little – read the book – respected – lived simple – called – grandfather – saint – spent life peacefully.
Ivan Dmitrich Aksionov was condemned to be flogged and sent to the mines. So he was flogged with a knot and when the wounds made by the knot were healed, he was driven to Siberia with other convicts. For twenty-six years Aksionov lived as a convict in Siberia.

In prison, Aksionov learned to make boots and earned a little money, with which he bought the book “The lives of saints”. He read the book when there was sufficient light in prison. On Sundays, he read the lessons and sang in the choir. The prison authorities liked him for his meekness. Fellow prisoners, having realized that he was innocent, respected him and called him grandfather. He was made their spokesperson petition their genuine grievances in the jail. When there were quarrels among the prisoners, they brought their cases to Aksionov for settlement. The jail authorities respected him for his exemplary manners.

Question d.
Why did Aksionov decide not to reveal the truth about Makar Semyonich?
Answer:
Aksionov – a fresh gang of convicts – old prisoners met the newcomers from towns – villages – no speak of his misfortune – Makar – the real murderer – repeat his prayers – telling the truth – government release.

Ivan Dmitrich Aksionov met a fresh gang of convicts, came to the prison one day. In the evening the old prisoners collected the new prisoners and asked them what towns or villages they came from and what for they were sentenced. Aksionov sat down near the newcomers and listened to what was said, one of the new convicts, a tall, strong man of sixty with a closely-cropped grey beard was telling the others why he had been arrested for. He said that he was arrested and accused of stealing and thereby came to prison.

When he was asked where he was from, he said that he was from Vladimir. At once Aksionov raised his head and asked about his family. Makar Semyonich asked Aksionov how he came here. But Aksionov did not like to speak of his misfortune. He only sighed and said “For my sins, I have been in prison these twenty-six years” After a long conversation with Makar Semyonich, he came to know that Makar was the real murderer and he was the real culprit behind all his sufferings lasted for twenty-six years.

He kept repeating prayers all night but could get no peace. Aksionov felt that if he had told the truth to the governor he might be released from the prison but he thought not to perish the life of Makar. So he decided not to reveal the truth about Makar Semyonich.

Question e.
Discuss the meaning and importance of the saying “God sees the truth but waits”
Answer:
According – Leo Tolstoy – important element – last two words – but waits – Aksinov – innocent – a clever reader – very much respected – justice arrived – end of the story Makar confesses – Aksionov dies

According to Leo Tolstoy, it is important not to neglect the last two words of the title. “But waits”. An important element of the story is that the truth comes out only after waiting a long time. The reader knows from the very beginning that Aksionov is innocent; a clever reader and even in the prison he was very much respected. Justice, however, is not arrived at until the very end of the story. When years later after the crime Makar confesses and Aksionov dies a contented man. The ‘moral’ of the story is debatable whether Tolstoy is saying that God will eventually bring justice to every situation or pointing out that justice sometimes arrives too late.

Question f.
Forgiveness is the best form of revenge. Substantiate the statement with reference to the story.
Answer:
The theme of guilt – faith – conflict – forgiveness – freedom – acceptance – faith in god – merchant’s murder – Aksionov’s prison life – Makar’s regret – begging for forgiveness – Aksionov’s patience.

There are two important conflicts that help the reader understand Ivan Aksionov’s character. He is condemned for a murder he had not committed. He is hurt more when his wife also suspects him. He submits himself totally to God and expecting mercy and forgiveness only from him. But when he faces another enquiry within the prison, he is forced to tell the truth about Makar. But instead of exposing the sinner Makar, he allows God to take over and keeps quiet. Remorseful Makar seeks his forgiveness in prison. There is a debate with his conscience

“To forgive or not”. Then he tells Makar, “God will forgive you. Maybe I am a hundred times worse than you. Both Makar and Aksionov come to an understanding that God’s forgiveness and mercy towards humans are incomprehensible. If Aksionov had exposed Makar and got him punished, Makar would never have felt guilty and asked for Ivan’s forgiveness. It is true “Forgiveness is the sweetest form of revenge.”

Paragraph:

Life of Aksionov:
Once there lived a young merchant named Ivan Dmitrich Aksionov with his family in Vladimir, Before he got married, he experienced all the material things in his younger days.

Bad dream:
One summer, he planned to go to the Nizhny fair. But his wife warned him that she dreamt bad about Aksionov that when he returned home from the tour his hair was turned grey. Aksionov laughed as if he did not care and went on the fair. He travelled halfway and met a merchant whom he spent the night in an inn. The next morning he woke up early and continued his journey.

Murder and arrest:
During his journey, two soldiers in a troika stopped him and began asking questions about the merchant he met halfway on his travel who was found dead. So he was arrested and imprisoned. Hearing the sad fate of Aksionov, his wife was also remembered of her dream about Aksionov; She was worried and considered the thought of her husband being guilty.

Prison life:
Twenty-six years in prison made Aksionov a well-grounded and god-fearing man in spite of the feat that his family has completely forgotten him. He still serves as a grandpa to the other prisoners. Then there came a new prisoner named Makar Semyonich. Aksionov discovered that Makar was the one who killed the merchant. He was furious with what he found out but he didn’t speak a word about it.

Makar the real murderer:
One day at night, Aksionov heard some earth rolling under where the prisoners were sleeping. He went out and saw Makar. Makar told him not to tell about that, else he would kill him. When they were led out to work, a soldier planned and found the tunnel. Then the soldier asked everyone but nobody dared to witness against Makar. Aksionov was closely questioned by the governor of the prison because the governor knew that his testimony would be honest. But he did not want to see Makar harshly punished.

Conclusion:
At night, Makar came to Aksionov’s bed and begged the old man for forgiveness. He confessed that he had indeed killed the merchant and he had hidden the bloody knife in Aksionov’s bag. Makar continued to beg Aksionov for forgiveness. Both men were soon weeping and Aksionov said “God will forgive you” when the day for release came, he was found dead.

God Sees the Truth, But Waits Summary in Tamil

இந்த கதை, ஆக்சியோநவ் என்ற ஓர் இளம் வணிகரின் விசுவாசம், மன்னிக்கும் தன்மை, சுதந்திரம் மற்றும் ஏற்புடைமையைப் பற்றியது. இவர் தாம் செய்யாத குற்றத்திற்காக சிறைவாசம் அடைகிறார்.

விலாடிமிர் (Vladimir) என்ற நகரத்தில் ஒரு இளம் வியாபாரி (merchant) வாழ்ந்து வந்தார். அவருடைய பெயர் ஐவன் ட்மிட்ரிச் அக்சியோநவ் (Ivan Dmitrich Aksionov). அவர் சொந்தமாக ஒரு வீட்டையும், இரு கடைகளையும் வைத்திருந்தார்.

அக்சியோநவ் அழகு வாய்ந்தவன். அழகிய முடிகளைக் கொண்ட அலை வளைவு போன்ற தலைமுடியை உடையவர். அவர் நகைச்சுவை தன்மை மிக்கவன். பாடல் பாடுவதில் நாட்டம் கொண்டவர். இந்த அமைதியான மனிதர் குடிக்கக் கொடுத்தால், விதிகளை மீறும் வரை குடித்துக் கொண்டே இருப்பார். ஆனால் திருமணத்திற்குப் பின் தன் குடிப்பழக்கத்தைத் துறந்தார்.

ஒரு கோடைக்காலத்தில் அக்சியோநவ், நிஸ்னி கண்காட்சிக்குச் (Nizhny Fair) சென்றான். தம் குடும்பத்திலிருந்து விடைபெறுவதைக் கூறும்போது, அவனது மனைவி, “ஐவன் ட்மிட்ரிச், இன்று நீங்கள் செல்ல வேண்டாம், ஏனெனில் உங்களைப் பற்றி தீய கனவு (bad dream) ஒன்றைக் கண்டேன்” என்றாள்.

அதற்கு அக்சியோநவ் “நான் கண்காட்சிக்குச் சென்றதும் களிப்பூட்டும் குடிவெறியாட்டம் போடுவேன் என்று அஞ்சுகிறாயா?” என்று சிரித்துக்கொண்டே கூறினான். அதற்கு அவர் மனைவி “நான் எதற்கு அஞ்சுகிறேன் என்று எனக்குத் தெரியாது. எனக்குத் தெரிந்ததெல்லாம் அந்த தீய கனவைப் பற்றிதான். எனது கனவில், நீங்கள் நகரத்தை விட்டு திரும்பும்போது தொப்பியைக் கழற்றுகிறீர்கள் அப்போது நான் உங்கள் தலைமுடியனைத்தும் நரைத்து இருப்பதைக் காண்கிறேன்” என்றாள்.

அக்சியோநவ் சிரித்தார். “அது அதிர்ஷ்டத்தின் அடையாளம்” என்றார். “இதோ பார், நான் எனது பொருள்களை விற்கவில்லை என்றாலும் உனக்கு அங்கிருந்து பரிசுகளைக் கொண்டு வருகிறேன்” என்றான்.

அதனால் அவர் தனது குடும்பத்திடமிருந்து விடைபெற்றுசென்றார். அவர் பாதிதொலைவில் சென்றுகொண்டிருக்கும் போது, அக்சியோநவ் தனக்கு அறிமுகமான ஒரு வியாபாரியை சந்தித்தான். அவர்கள் அன்றிரவு தங்குவதற்கு ஒரே விடுதியைப் (inn) பதிவு செய்திருந்தனர். அவர்கள் இருவரும் சேர்ந்தே தேனீர் அருந்தினர். பிறகு அவர்கள் படுக்கைக்குச் சென்றனர்.

இரவு தாமதமாக உறங்க செல்வதும், குளிரில் பயணிப்பதும் அக்சியோநவ்வின் பழக்கமன்று. அவர் விடியும் முன் தனது ஓட்டுநரை எழுப்பி விட்டு குதிரைகளை (horses) ஆய்த்தப் படுத்தக் கூறினான்.

பின்னர், அவன் தனது விடுதியின் உரிமையாளரிடம், (விடுதிக்குப் பின்புறம் உள்ள சுவரின் வீட்டிற்கு சென்று விடுதியின் கட்டணத்தை கட்டிவிட்டு தனது பயணத்தைத் தொடர்ந்தார்.

இருபத்தைந்து மைல் தூரம் சென்றபின், குதிரைகளுக்கு உணவளிப்பதற்காக நிறுத்தினார். அக்சியோநவ் வழியோரம் இருந்த விடுதியில் ஓய்வெடுத்துக் (rested) கொண்டிருந்தார். பிறகு விடுதியின் முற்றத்திற்கு (porch) வந்து தேனீர் பாத்திரத்தை சூடுபடுத்த கட்டளையிட்டார். தனது இசைக் கருவியைக் (guitar) கொண்டு வாசிக்கத் தொடங்கினார்.

திடீரென்று மூன்று குதிரைகள் பூட்டப்பட்ட வண்டி மணியோசையுடன் வந்தது. ஓர் அதிகாரி இரண்டு படைவீரர்களுடன் (soldiers) கீழிறங்கினார். அவர் அக்சியோநவ்விடம் வந்து கேள்விகள் கேட்கத் தொடங்கினார். அவர் யார் என்றும், எப்பொழுது இங்கே வந்தார் என்றும் வினவினார். அக்சியோநவ் அனைத்தையும் கூறி, “என்னுடன் தேனீர் அருந்துகிறீர்களா?” என்றான்.

ஆனால் அதிகாரி அவனிடம் குறுக்கு கேள்வி கேட்டார். அவனிடம், “நேற்றிரவு எங்கே கழித்தீர்கள்? என்றும் நீ மட்டுமா அல்லது வேறு வியாபாரியுடன் தங்கி இருந்தாரா? என்றும் காலையில் வியாபாரியை பார்த்தீர்களா? என்றும் பொழுதுவிடியும் முன் ஏன் விடுதியிலிருந்து வந்தீர்கள்? என்றும் கேட்டார்.

ஏன் இவ்வளவு வினாக்கள் தன்னிடம் கேட்கப்பட்டன என்று வியப்படைந்தான் அக்சியோநவ். ஆனால் அனைத்திற்கும் விடையளித்தான். கூடதலாக “ஏன் என்னிடம் இவ்வளவு குறுக்கு வினாக்கள், நான் என்ன திருடனா (thief) அல்லது கொள்ளையனா (robber)? நான் எனது வியாபாரத்திற்காகப் பயணித்துக் கொண்டிருக்கிறேன் மற்றும் என்னிடம் கேள்வி கேட்க வேண்டியதில்லை’ என்றார்.

பின்னர் அந்த அதிகாரி, படைவீரர்களை அழைத்து அக்சியோநாவிடம் “நான் இந்த மாவட்டத்தின் காவல் அதிகாரி, நான் உன்னிடம் ஏன் வினா கேட்கிறேனென்றால் நீ எந்த வியாபாரியுடன் நேற்றைய இரவைக் கழித்தாயோ அவர் தற்போது கழுத்து வெட்டுண்டு இறந்து கிடக்கிறார்” ஆகவே நாங்கள் நிச்சயமாக உன் பொருள்களைச் சோதிக்க வேண்டும்,” என்று கூறினார்.

அவர்கள் வீட்டினுள் நுழைந்தனர் (entered). படைவீரர்களும், காவல் அதிகாரியும் அக்சியோநவ்வின் மூட்டை (luggage) முடிச்சை அவிழ்த்து தேடினார். உடனே அதிகாரி மூட்டையிலிருந்து ஒரு கத்தியை எடுத்தார். “இது யாருடையது?” என்று கத்தினார். தனது பையிலிருந்து வெளியே எடுக்கப்பட்ட இரத்தக்கறைப் படிந்த கத்தியைப் பார்த்து அக்சியோநவ் அச்சமடைந்தார். “எப்படி இந்த கத்தியின் மேல் இரத்தம் படிந்தது?”

அக்சியோநவ் பதிலளிக்க முயன்றான் ஆனால் தொடர்ச்சியாக பேசமுடியவில்லை. எனக்கு தெரியாது…… என்னுடையது இல்லை ….. என்று திக்கித் திக்கிக் (stammered) கூறினார். “இந்தக் காலைபொழுதில் அந்த வியாபாரி அவரது படுக்கையில் கழுத்து வெட்டுண்டு கிடந்தார்”, உங்களால் மட்டும்தான் இதைச் செய்திருக்க முடியும். அந்த வீடு உள்ளிருந்து பூட்டப்பட்டிருந்தது மற்றும் அங்கு வேறு யாரும் இல்லை .

இங்கு இரத்தம் படிந்த கத்தி (blood stained knief) உங்கள் பையில் இருக்கிறது மற்றும் உங்களது முகமும், போக்கும் உங்களைக் காட்டிக்கொடுக்கின்றன. எவ்வாறு நீங்கள் அவனை கொன்றீர்கள், எவ்வளவு பணம் நீங்கள் கொள்ளையடித்தீர்கள்?” என்று என்னிடம் கூறுங்கள்” என்று கேட்டார்.

அக்சியோநவ், தான் தவறு செய்யவில்லை என்று அவனுக்கு உறுதியாக தெரியும், அவனும், கொலையுண்ட வியாபாரியும் சேர்ந்து தேனீர் அருந்தியபின், அந்த வணிகரை அக்சியோநவ் பார்க்கவில்லை . அவனிடம் எட்டாயிரம் ரூபிள்கள் (rubles) தவிர வேறு பணம் இல்லை மற்றும் அந்த கத்தி அவனுடையதன்று. ஆனால் அவனது குரலில் தடுமாற்றம் எழுந்தது, முகம் வெளிறிப் போனது (pale) மற்றும் அவன் பயத்தால் ஆட்கொள்ளப்பட்டார். இருப்பினும் பழிக்குற்றத்திற்குத் (guilty) தள்ளப்பட்டார்.

அந்த காவல் அதிகாரி, அக்சியோநவ்வைக் கட்டி (bind) வண்டியிலேற்றும்படி படைவீரர்களுக்கு கட்டளையிட்டார். அவர்கள் அச்சியோநவ்வின் கால்களைச் சேர்த்துக்கட்டி வண்டியிலேற்றினர். அக்சியோநவ் தனக்குத்தானே சிலுவையை (cross) தொட்டு அழுதார். அவரது பணமும் மற்றும் பொருட்களும் அவனிடமிருந்து பறிக்கப்பட்டன. அவர் பக்கத்து நகரத்துக்கு அனுப்பப்பட்டு சிறையிலடைக்கப்பட்டார்.

விலாடிமிரில் (Vladimir) அவனைப் பற்றிய விசாரணை (enquiries) நடத்தப்பட்டது. அங்குள்ள வியாபாரிகளும், குடிமக்களும் முந்தைய நாட்களில் அவன் குடித்துக்கொண்டு நேரத்தை வீணாக்கிக் கொண்டிருப்பான், ஆனால் அவன் நல்ல மனிதனாக மாறி விட்டான் என்று கூறினர். பின்பு விசாரணை தொடங்கியது, ரையாசான் வியாபாரியைக் கொன்றதாகவும், இருபதாயிரம் ரூபிள்களைக் கொள்ளையடித்ததாகவும் பழிச்சுமத்தப்பட்டார்.

அவனது மனைவி நம்பிக்கையிழந்து இருந்தாள். அவருக்கு எதை நம்புவது என்று தெரியவில்லை. அவளுடைய குழந்தைகள் அனைவருமே மிகச்சிறியவர்கள், ஒரு குழந்தை தாய்ப்பால் குடிக்கும் பருவத்தில் இருந்தது. அனைவரையும் தன்னுடன் கூட்டிக்கொண்டு, தன் கணவன் சிறையிலடைக்கப்பட்டிருக்கும் நகரத்திற்குச் சென்றாள். முதலில் அவள், தன் கணவனைப் பார்பதற்கு அனுமதி அளிக்கப்படவில்லை. ஆனால் பிறகு மிகவும் கெஞ்சியப்பின், மேலதிகாரியால் அனுமதிக்கப்பட்டு அவனிடம் கொண்டுச் செல்லப்பட்டாள்.

தனது கணவனைக் கைதி உடையில் விலங்கிட்டு குற்றவாளிகள் மற்றும் திருடர்கள் மத்தியில் பார்த்தவுடன் அவள் கீழே விழுந்தாள். நீண்ட நேரம் வரை எழவில்லை . பிறகு தன் குழுந்தைகளை தூக்கிக்கொண்டு, தன் கணவன் அருகில் அமர்ந்தாள். வீட்டு நடப்பை அவரிடம் கூறினாள். அவருக்கு என்ன நேர்ந்தது என்று கேட்டாள். அவன் அனைத்தையும் அவளிடம் கூறினான். “நாம் இப்போது என்ன செய்வது?” என்று அவள் கேட்டாள்.

”நாம் கண்டிப்பாக சிசார் மன்னருக்கு ஒரு நிரபராதி அழிவிற்கு செல்லவேண்டாம்” என்று மனு செய்ய வேண்டும் ஆனால், தான் சிசார் மன்னருக்கு விண்ணப்பம் அனுப்பியதையும், அது ஏற்றுக் கொள்ளப் படாததையும் பற்றி அவள் தன் கணவனிடம் கூறினாள்.

அவன் எதுவும் கூறவில்லை . ஆனால் ஊக்கம் குறைந்தபடி காணப்பட்டான்.

பிறகு அவன் மனைவி கூறினாள், “ இது ஒன்றும் பயனில்லை. நான் அன்று உங்கள் தலைமுடி நரைத்து விட்டதாகக் கனவு கண்டேன். நினைவில் உள்ளதா? அந்த நாளில் செல்ல வேண்டாம் என்றேன். அவள் தன் விரல்களை அவன் முடிகளினுள் விட்டு கூறினாள் “வாண்யா (ஐவன் என்பதன் செல்லப் பெயர்) அன்பிற்குரியவரே உண்மையை உங்கள் மனைவியிடம் கூறுங்கள், நீங்கள் இல்லை என்றால் யார் செய்தார்?”

அதனால் நீ கூட என்னை சந்தேகிக்கிறாயா! என்று முகத்தை கைகளால் மூடி (hiding) அழத் தொடங்கினான். பிறகு ஒரு படைவீரர் அவனது மனைவியிடமும், குழந்தைகளிடமும் “இங்கேயிருந்து செல்லுங்கள்” என்றான். அக்சியோநவ் அவனது குடும்பத்திற்கு கடைசி முறையாக பிரியா விடை கொடுத்தார்.

அவர்கள் சென்றதும், அக்சியோநவ் பேசியதனைத்தையும் மீண்டும் நினைவு படுத்திப் பார்த்தார். எப்போது தன் மனைவி தன்னைச் சந்தேகப்பட்டு கேட்ட வினாக்கள் நினைவில் எழுந்ததோ, அவன் தனக்குத் தானே “கடவுளுக்கு மட்டும் உண்மை தெரியும், அவனிடம் மட்டும்தான் முறையீடு செய்ய முடியும் மற்றும் அவனிடம் மட்டும் தான் இரக்கத்தை எதிர்ப்பார்க்கமுடியும் என்று கூறிக்கொண்டான் மற்றும் அக்சியோநவ் மேலும் எந்த விண்ணப்பங்களையும் எழுதவில்லை, அனைத்து நம்பிக்கைகளையும் கைவிட்டுவிட்டு, கடவுளை வணங்கத் தொடங்கினார்.

பிரம்பால் அடிபடுவதற்கும், சுரங்கத்திற்குச் செல்வதற்கும் ஆழ்ந்த வெறுப்பு தெரிவித்தார். அக்சியோநவ் அதனால் சாட்டையால் அடிக்கப்பட்டார். சாட்டையடியால் ஏற்பட்ட காயங்கள் ஆறியபின் மற்ற குற்றவாளிகளுடன் சிபோரியாவிற்கு கொண்டு செல்லப்பட்டார்.

இருபத்தாறு ஆண்டுகளுக்கு அக்சியோநவ் குற்றவாளியாக சைபீரியா சிறையில் வாழ்ந்தார். அவரது முடி பனிப்போன்று வெண்மையாயின. அவரது தாடி நீளமாக வளர்ந்து, மெல்லியதாக நரைத்துக் காணப்பட்டது. அவனது அனைத்து மகிழ்ச்சியும் சென்றுவிட்டன, அவனுக்கு கூன் விழுந்தது, மெதுவாக நடந்தார், குறைவாக பேசினார் மற்றும் சிரிக்காமலேயே இருந்தார். ஆனால் அவர் கடவுளைத் துதித்துக் கொண்டே இருந்தார்.

சிறையில் அக்சியோநவ் காலணி (boots) செய்வதைக் கற்றுக்கொண்டு அதன் மூலம் சிறிது பணத்தைச் சம்பாதித்தார். அவற்றைக் கொண்டு “புனிதர்களின் வாழ்வு” என்ற நூலை வாங்கினார். அவர் அந்த நூலை, சிறையில் போதிய ஒளி இருக்கும்போது வாசித்தார். ஞாயிற்றுக்கிழமைகளில் சிறையில் இருக்கும் தேவாலயத்தில் புனித நூல்களை வாசித்தும், பாடல் குழுவில் இணைந்து பாடல்கள் பாடியும் வழிபட்டார். அவருடைய குரல் அப்போதும் நன்றாக இருந்தது.

சிறை அதிகாரிகள் மென்மை (meekness) குணத்திற்காக அக்சியோநவ்வை நேசித்தனர். சக குற்றவாளிகள் அவரை மதித்தனர். அவர்கள் அவரை “தாத்தா” என்றும் “புனிதர்” என்றும் அழைத்தனர். சிறை அதிகாரிகளிடம் ஏதேனும் விண்ணப்பம் எழுப்பினால் அனைவர் சார்பாக அக்சியோநவ்வே பேசுவார். குற்றவாளிகளுக்குள் மோதல் ஏற்பட்டால் அந்த பிரச்சனை அக்சியோநவ்விடம் கொண்டுவரப்பட்டு தீர்க்கப்பட்டது.

தன் வீட்டிலிருந்து எந்த செய்தியும் அக்சியோநவ்விடம் வந்து சேரவில்லை. மனைவியும், குழந்தைகளும் உயிரோடு இருக்கின்றனரா என்று கூட அவருக்குத் தெரியவில்லை . ஒரு நாள், ஒரு புது குற்றவாளிக் குழு சிறைக்கு வந்தடைந்தது. மாலைப் பொழுதில் பழைய குற்றவாளிகள் புது குற்றவாளிகளை வட்டமாக அமரச்செய்து, எந்த நகரம் அல்லது கிராமத்திலிருந்து வருகிறீர்கள் என்றும், எதற்காகச் சிறைக்கு அடைக்கப்பட்டார்கள் என்றும் விசாரித்தனர். அக்சியோநவ்வோ மகிழ்ச்சி குறைந்தவராய் புது குற்றவாளிகள் அருகில் அமர்ந்து அவர்கள் கூறியதைக் கேட்டுக்கொண்டிருந்தார்.

புது குற்றவாளிகளுள் ஒருவர், உயரமாக அறுபது வயது பொருந்திய உறுதியான, நரைத்த தாடியுடன் இருந்தார். எதற்காக அவர் கைது செய்யப்பட்டார் என்பதைக் கூறிக்கொண்டிருந்தார்.

“நல்லது நண்பர்களே”, என்று அவர் கூறினார். “நான் பனிப்பிரதேசத்தில் வண்டியை இழுத்துச் (sledge) செல்லும் ஒரு குதிரையைத் திருடினேன். நான் அதற்காகக் கைது செய்யப்பட்டு சிறைவாசம் அனுபவிக்கிறேன்” என்றான்.

தான் அக்குதிரையை வீட்டிற்கு விரைவாகச் செல்வதற்கு எடுத்ததாகவும், பிறகு விட்டுவிடலாம் என்று இருந்ததாகவும் மேலும் அக்குதிரை ஓட்டுநர் தனக்குத் தனிப்பட்ட நண்பர் என்றும், ஆதலால் ‘இது சரியே’ என்றும் கூறினார். ஆனால் அவர்கள் ‘இல்லை ‘ ‘நீ இதைத் திருடிவிட்டாய்’ என்றனர்.

ஆனால் எங்கு அல்லது எப்படி திருடினேன் என்று அவர்கள் கூறவில்லை . ஒரு நாள் நான் சில தவறுகள் செய்தேன். அதன் கட்டாயமான முன்பு இங்கே வந்தேன். ஆனால் அப்பொழுது என்னைக் கண்டுபிடிக்கவில்லை. இப்போது எதுவும் செய்யவில்லை ஆனாலும் இங்கே அனுப்பப்பட்டிருக்கிறேன்……. ஆனால் தற்போது கூறுவது பொய். முன்பு சைபீரியாவில் இருந்தேன், ஆனால் வெகுகாலம் அல்ல.”

“எங்கிருந்து வருகிறீர்கள்” என்று சிலர் கேட்டனர். ஒருவர் கேட்டார். “விலாடிமிர்ரிலிருந்து”.

எனது குடும்பம் அங்குள்ள நகரத்தில் இருக்கிறது. எனது பெயர் மகர் (makar) மற்றும் சிலர் என்னை செம்யோனிச் (semyonich) என்று அழைப்பர், அக்சியோநவ்தலையைத் தூக்கி “கூறு, செம்யோனிச் உனக்குவிலாடிமிர்ரைச் சேர்ந்த வியாபாரி அக்சியோநவ்வைப் பற்றித் தெரியுமா? அவர்கள் இன்றும் வாழ்கின்றனரா?”

“அவர்களைத் தெரியுமா? நன்றாகத் தெரியும். அந்த அக்சியோநவ் பணக்காரர், அவர்களின் தந்தை சிபேரியாவிலிருந்தாலும். அவர் நம்மைப் போன்ற பாவி, தாத்தா நீங்கள் எவ்வாறு இங்கு வந்தீர்கள்?”

அக்சியோநவ் தன் துரதிஷ்டத்தைப் பற்றி கூற விரும்பவில்லை . அவர் ஒரு பெருமூச்சு விட்டு கூறினார், “எனது பாவங்களுக்காக இந்த சிறையில் இருபத்தாறு ஆண்டுகள் இருக்கிறேன்”.

“என்ன பாவங்கள்?” என்று கேட்டார் மகர் செம்யோனிச்.

ஆனால் அக்சியோநவ் “விடுங்கள், விடுங்கள் நான். இதற்கு தகுதியுடையவன் தான்” என்று மட்டும் கூறினார். ஆனால் அவருடைய சகதோழர்கள் புதிய நண்பர்களிடம் எவ்வாறு அக்சியோநவ் சிபேரியாவிற்கு வந்தார் என்றும், எவ்வாறு மர்ம நபர் ஒருவர் ஒரு வியாபாரியைக் கொன்று விட்டு அந்தக் கத்தியை அக்சியோநவ் பையில் மற்ற பொருள்களோடு வைத்தவிட்டுச் சென்றதையும் கூறினார்கள் அதனால் அக்சியொநவ் அநியாயமாக தண்டிக்கப்பட்டார் என்றும் கூறினார்கள்.

இதை மகர் செம்யோனிக் கேட்டதும், அக்சியோநவ்வைப் பார்த்து, தன் மூட்டினை (knee) அடித்துக்கொண்டு (slapped) வியந்து, “இது வியப்பாக உள்ளது! உண்மையிலேயே வியப்பு! ஆனால் நீங்கள் முதுமை அடைந்து வீட்டீர்களே! தாத்தா! என்றார்.

மற்றவர்கள் அவரிடம் (மகரிடம்) எதற்காக அவன் இவ்வளவு ஆச்சரியப்படுகிறான், அவனுக்கு முன்னதாகவே அக்சியோநவ்வைத் தெரியுமா என்றும் வினவினர், ஆனால் மகர் செம்யோனிச் பதில் ஏதும் கூறவில்லை . இதில் வியப்பு என்னவென்றால் “நாம் இங்கு சந்திக்கிறோம் சிறுவர்களே! (lads)” என்று மட்டும் உரைத்தான்.

இவ்வார்த்தைகள் அக்சியோநவ்வைவியப்பூட்டியது. ஏனென்றால் ஒரு வேளை இம்மனிதருக்கு அந்த வியாபாரியைக் கொன்றவனைப் பற்றித் தெரியுமோ என்று. ஆதலால் அவர் ஒருவேளை செம்யோனிச் உங்களுக்கு அந்த விவகாரம் பற்றித் தெரிந்திருக்கலாம் அல்லது எப்போதாவது முன்பு என்னைப் பார்த்திருக்கிறீர்களா?” என்று கேட்டார்.

“நான் கேட்டதை வைத்து உங்களுக்கு எவ்வாறு உதவ முடியும்? இந்த உலகம் வதந்திகளால் நிறைந்துள்ளது. ஆனால் இது நீண்ட காலத்துக்கு முன்பு நான் என்ன கேட்டேன் என்பதை மறந்துவிட்டேன் “ஒருவேளையார் அந்த வியாபாரியைக் கொன்றிருப்பார்? என்பதை நீங்கள் கேட்டிருப்பாய்” என்றார் அக்சியோநவ்.

மகர் செம்யோனிச் சிரித்துக்கொண்டே “கத்தியை எவர் மறைத்து வைத்தாரோ அவர் பிடிபடும்வரை குற்றவாளியல்ல.” என்று கூறினார். “உங்கள் கண்காணிப்பில் இருக்கும்போது யாரால் கத்தியை உங்கள் பையில் போட முடியும்? இது நிச்சயமாக உங்களிடத்தில் விழிப்புணர்வை ஏற்படுத்தியிருக்கும்”.

எப்பொழுது இவ்வார்த்தைகளை அக்சியோநவ் கேட்டாரோ, அப்பொழுதே இந்த மனிதர்தான் அந்த வியாபாரியை கொன்றிருப்பார் என்று உறுதி செய்தார். அவர் எழுந்து அங்கிருந்து சென்றார். அன்றிரவு முழுவதும் அக்சியோநவ் விழித்துக் (awake) கொண்டிருந்தார். அவர் பயங்கரச் (terribly) சோகத்தில் ஆழ்ந்தார். பலவிதமான கற்பனைகளும் அவர் மனதில் எழுந்தன. அவர் கண்காட்சிக்கு (fair) செல்லும் முன் தன் மனைவியுடன் இருந்த தருணங்கள் நினைவிற்கு வந்தன.

அவர் கண்முன் தன் மனைவியின் குரல், பேச்சு மற்றும் சிரிப்புத் தோன்றின. பிறகு அப்போது சிறுவர்களாக இருந்த குழந்தைகள் கண் முன் தோன்றினர். ஒரு குழந்தை சிறிய மேலங்கியுடனும், மற்றொன்று தாய்ப்பால் குடிக்கும் பருவத்திலும் இருந்தது. அவர் இளமையாகவும், சந்தோசமாகவும் இருந்த தருணங்கள் நினைவிற்கு வந்தன.

அவர் கைதுசெய்யப்பட்ட இடத்தில் இருந்த திண்ணையில் அவர் இசைக்கருவி வாசித்ததும், சவுக்கு அடி வாங்கியதும், மக்கள் அவரைச் சுற்றி நின்றதும், சங்கிலியும், குற்றவாளிகளும், சிறைவாழ்க்கையும் அவருடைய முதிர்வும் அவரின் நினைவிற்கு வந்தன. இந்த அனைத்துச் சிந்தனைகளும் அவரை பரிதாபமாக (wretched) மாற்றி தன்னைத்தானே கொல்வதற்கு ஆயத்தப்படுத்தியது (ready).

“இவையனைத்தும் அந்த வில்லன் செய்தது” என்று சிந்தித்தார் அக்சியோநவ். அவரது கோபம் மகர் செம்யோனிச் மீது பெருகியது. தான் இறந்தாலும் அவரைப் பழித்தீர்த்துவிடவேண்டும் என்று எண்ணினார். அவர் அனைத்து இரவுப் பொழுதுகளிலும் இறைவனிடம் வேண்டினார். ஆனாலும் அவருக்கு அமைதி கிடைக்கவில்லை. அந்த நாட்களில் அக்சியோநவ் செம்யோனிச்சின் அருகில் செல்லவும் இல்லை, அவரைப் பார்க்கவும் இல்லை.

இரண்டு வாரம் கழிந்தது. அன்றிரவு அக்சியோநவ் உறங்கவில்லை, தான் அடுத்து என்ன செய்யப் போவது என்று தெரியாமல் பரிதாபமாக (miserable) இருந்தார்.

ஓர் இரவு, அவர் சிறையில் நடந்துக்கொண்டிருக்கும்போது கைதிகள் உறங்கும் பலகையின் கீழ் நிலத்தைத் தோண்டிக்கொண்டு யாரோ வருவதைக் கண்டார். அவர் தன்னை நிறுத்திக்கொண்டு என்ன நடக்கிறது என்பதனைக் கவனித்தார். திடீரென அந்த படுக்கையில் கீழிருந்து மகர் செம்யோனிச் வெளியேறினார். முகத்தில் பதட்டத்துடன் அக்சியோநவ்வைக் கண்டார்.

அக்சியோநவ் அவரைக் காணாததுப்போல் சென்றுவிடப் பார்த்தார் ஆனால் மகர் அவரது கையைப் பற்றிக்கொண்ட அவரிடம் தான் சுரங்கத்தின் வழியே தப்பிப்பதற்கு ஒரு குழியைத் தோண்டுவதாகவும், தோண்டியவற்றை தன் நீண்ட காலணியில் வைத்து தினமும் கைதிகள் வேலைக்கு செல்லும்போது அவற்றை சாலையில் அப்புறப்படுத்திவிடுவதற்கும் ஏற்பாடு செய்துள்ளதாகவும் கூறினார்.

“அமைதியாக இருங்கள் வயதானவரே, நீங்களும் வெளியேறலாம் முட்டாள்தனமாக இந்த ரகசியத்தை வெளியே கூறினால், அவர்கள் என்னை சவுக்கால் வாழ்க்கை முழுவதும் அடிப்பார்கள், ஆனால் நான் முதலில் உங்களைக் கொன்றுவிடுவேன்” என்றான்.

“அவர் தன் எதிரியைப் பார்க்கும்போது கோபத்தால் நடுக்கமுற்றார். அவர் தன் கையை விடுவித்துக் கொண்டு “எனக்கு இங்கிருந்து தப்பித்து செல்ல ஆசையில்லை. நீ என்னை கொல்ல தேவையில்லை, நீ என்னை முன்பே கொன்றுவிட்டாய், நான் ஒருவேளை நீ கூறியபடி நடக்கலாம், இல்லாமலும் இருக்கலாம், அது கடவுள் வழிநடத்துவதைப் பொருத்தது.” என்று கூறினார்.

அடுத்த நாள், கைதிகள் வேலைக்காக வெளியே சென்றதும், படைவீரர், கைதிகளில் ஒரு சிலர் மணலை தங்கள் காலணியிலிருந்து வெளியே கொட்டுவதைக் கவனித்தார். சிறையில் தேடப்பட்ட அந்த சுரங்கம் கண்டறியப்பட்டது. ஆளுநர் அங்குள்ள அனைத்துக் கைதிகளிடமும் யார் இதைத் தோண்டியிருப்பார் என்று அறிந்துகொள்ள விசாரணை நடத்தினார். அவர்கள் அனைவரும் மறுத்துவிட்டனர் ஏனெனில் அவற்றைக் கூறினால் செம்யோனிச்சுக்குச் சாகும் வரை சவுக்கு அடி விழும் என்பது அவர்களுக்குத் தெரியும்.

இறுதியாக ஆளுநர் அக்சியோநவ்விடம், “நீங்கள் உண்மையான (அ) நேர்மையான முதியவர், கடவுள் சாட்சியாக யார் இந்த குழியைத் தோண்டியது?” என்று என்னிடம் கூறுங்கள் என்றார்.

மகர் செம்யோனிச் கவலையுற்றவனாய், ஆளுநரை பார்த்துக்கொண்டே அக்சியோநவ்வை நோக்கியபடி நின்றுக்கொண்டிருந்தார். அக்சியோநவ்வுடைய உதடுகள் மற்றும் கைகள் நடுங்கின, நீண்ட நேரத்திற்கு அவர் எதுவும் கூறவில்லை. “எதற்காக என் வாழ்க்கையை அழித்தவனைக் காட்டிக் கொடுக்க வேண்டும்?

நான் பட்ட கஷ்டத்துக்கு ஈடுகொடுக்கமுடியுமா?, ஆனால் நான் கூறினால் அவன் வாழ்க்கை முழுதும் சவுக்கு அடி பெறுவான், நான் அவனை தவறாகவும் கணித்திருக்கலாம் மற்றும் இதனால் நான் பெறும் பயன் என்ன?” என்று நினைத்தார்.

“நல்லது, பெரியவரே, என்றுரைத்தார் ஆளுநர்,” “உண்மையை என்னிடம் கூறுங்கள் யார் சுவற்றின் அடியில் குழியைத் தோண்டினார்?”

அக்சியோநவ் மகர் செம்யோனிச்சைப் பார்த்துவிட்டு பின்னர் கவர்னரிடம், “என்னால் கூற முடியாது, யுவர் ஆனர். நான் கூறுவது இறைவனின் விருப்பமன்று” என்றார்.

எவ்வளவு ஆளுநர் முயன்றும், அக்சியோநவ் ஒன்றும் கூறவில்லை. ஆகையால் அந்த விசாரணை கைவிடப்பட்டது.

அன்றிரவு, அக்சியோநவ் தன் படுக்கையில் படுத்திருந்தபோது யாரோ ஒருவர் அமைதியாக வந்து அவர் படுக்கையின் மேல் அமர்ந்தார். அவர் இருளில் கூர்ந்து நோக்கி அது மகர் தான் என்பதை உறுதி செய்தார்.

“என்னிடம் இன்னும் உனக்கு என்ன வேண்டும்?” என்று கேட்டார் அக்சியோநவ். “ எதற்காக நீ இங்கு வந்தாய்?”

மகர் செம்யோனிச் அமைதியாக இருந்தார். அதனால் அக்சியோநவ் எழுந்து, “உனக்கு என்ன வேண்டும்?” அங்கே போ, இல்லையேல் காவலரை நான் அழைப்பேன்” என்று கூறினார்.

மகர் செம்யோனிச் அக்சியோநவ்வை நெருங்கி மெதுவாக “ஐவன் டிமிட்ரிச் என்னை மன்னித்துவிடு” என்று கூறினார். “எதற்காக” என்று கேட்டார் அக்சியோநவ்.

“நான் தான் அந்த வியாபாரியைக் கொன்று அந்த கத்தியை உன் பொருட்களோடு மறைத்து வைத்தேன். நான் உன்னையும் கொன்றிருப்பேன் ஆனால் வெளியிலிருந்து சத்தத்தைக் கேட்டேன். ஆதலால் அந்தக் கத்தியை உன் பையில் மறைத்து வைத்துவிட்டு ஜன்னல் வழியே தப்பிச்சென்றேன்” என்றான்.

அக்சியோநவ் அமைதியாக என்ன கூறுவது என்று தெரியாமல் இருந்தார். மகர் செம்யோனிச் படுக்கையிலிருந்து படிப்படியாக கீழே இறங்கி தரையில் மண்டியிட்டு, “ஐவன் டிமிட்ரிச்” என்றார். அவர், “என்னை மன்னித்துவிடு, கடவுளின் அன்பிற்காக, என்னை மன்னித்துவிடு. நான் தான் அந்த வியாபாரியைக் கொன்றேன் என்று சொல்லி விடுகிறேன், நீ விடுதலைச் செய்யப்பட்டு உன் வீட்டிற்குச் செல்வாய்” என்றான்.

“இதைப் பேசுவதற்கு உனக்கு எளிமையாக இருக்கும்,” என்றார் அக்சியோநவ், “ஆனால் நான் உன்னால் இதற்காக இருபத்தாறு ஆண்டுகள் சிறையில் கஷ்டப்பட்டுக்கொண்டிருக்கிறேன். நான் இப்பொழுது எங்கு செல்வது? எனது மனைவி இறந்துவிட்டாள். எனது குழந்தைகள் என்னை மறந்துவிட்டனர். எங்கும் என்னால் செல்ல முடியாது ………….”

மகர் செம்யோனிச் எதுவும் கூறவில்லை. ஆனால் தன் தலையைத் தரையில் அடித்துக்கொண்டான். “ஐவன் டிமிரிச், என்னை மன்னித்து விடு என்று கத்தினார். அவர்கள் என்னை சவுக்கால் அடிக்கும்போது கூட இவ்வளவு வலியில்லை, ஆனால் உங்களை இந்நிலையில் பார்ப்பது வலிக்கிறது. இதுவரையிலும் உங்களுக்கு என்மேல் இரக்கமிருக்கிறது. கிறிஸ்துவின் பொருட்டு என்னை மன்னியும், துரதிஷ்டசாலி நான்” என்று சொல்லி அவன் அழத் தொடங்கினான்.

எப்போது அக்சியோநவ் மகர் அழுவதைக் கேட்டாரோ, அவரும் அழத் (sobbing) தொடங்கினார், “கடவுள் உன்னை மன்னிப்பார்” என்றார் அவர். “உன்னை விட நூறுமடங்கு துரதிஷ்டசாலி நானாக இருக்கலாம்” இவ்வார்த்தைகளில் அவரின் இதயம் ஒளிமிளிர்ந்தது. வீட்டின் ஏக்கத்தைப் பிரதிபலித்தது. அவருக்கு அந்த சிறையிலிருந்து செல்வதற்கு விருப்பமில்லை , ஆனால் அவர் தனது இறுதி நேரத்திற்காகக் காத்திருந்தார்.

அக்சியோநவ் என்ன சொன்னபோதிலும், மகர் தன் குற்ற உணர்ச்சியால் தனது குற்றத்தை ஏற்றுக்கொண்டான். ஆனால் சிறையிலிருந்து வெளிவருவதற்கான ஆணை வரும் பொழுது, ஏற்கனவே அக்சியோநவ் இறந்திருந்தார்.

statement
…….
……
statement_n
Where, statement in a class definition may be a variable declaration, decision control, loop or even a function definition. Variables defined inside a class are called as “Class Variable” and functions are called as “Methods”. Class variable and methods are together known as members of the class. The class members should be accessed through objects or instance of class. A class can be defined anywhere in a Python program.

Example: Program to define a class
class Sample:
x, y = 10, 20 # class variables
In the above code, name of the class is Sample and it has two variables x and y having the initial value 10 and 20 respectively. To access the values defined inside the class, you need an object or instance of the class.

Answer:
In Python a string literal is a sequence of characters surrounded by quotes. Python supports single, double and triple quotes for a string. A character literal is a single character surrounded by single or double quotes. The value with triple-quote is used to give multi-line string literal.

strings = “This is Python”
char = “C”
multilinestr = ‘”This is a multiline string with more than one line code.'”

Question 32.
Give an example program for Ternary operator?
Answer:
# Program to demonstrate conditional operator
a, b = 30, 20
# Copy value of a in min if a < b else copy b
min = a if a < b else b
print (“The Minimum of A and B is “,min)
# End of the Program

Output:
The Minimum of A and B is 20

Question 35(a).
Explain while loop with sample program?
Answer:
Syntax:
while <condition>:
statements block 1
[else:
statements block 2]

In the while loop, the condition is any valid Boolean expression returning True or False. The else part of while is optional part of while. The statements blockl is kept executed till the condition is True. If the else part is written, it is executed when the condition is tested False. Recall while loop belongs to entry check loop type, that is it is not executed even once if the condition is tested False in the beginning.

Example: program to illustrate the use of while loop – to print all numbers from 10 to 15

Output:
10 11 12 13 14 15

print(“First string = ” , string1)
print(” Second string = ” , string2)
temp = string1 string1 = string2
string2 = temp
print(“\n Both strings after swap : “)
print(“First string = ” , string1)
print(” Second string = “, string2)

Output:
Enter ‘X’ for exit
Enter first string : code
Enter second string : python
Both strings before swap:
First string = code Second string = python Both strings after swap:
First string = python Second string = code

Question 37 (a).

self.m2 = int(input(“Enter marks2”))
self, tot = self.m1 + self.m2
def disp(self):
print(self.name)
print(self.m1)
print(self.m2)
print(self.tot)
mlist = [ ]
st = stud( )
st.gdata( )
mlist.append(st)
for x in mlist:
x.disp( )

Output:

Question 38.
Write the different types of constraints and their functions?
Answer:
Constraints ensure database integrity, therefore known as database integrity constraints.

(I) Unique Constraint:
This constraint ensures that no two rows have the same value in the specified columns. For example UNIQUE constraint applied on Admno of student table ensures that no two students have the same admission number and the constraint can be used as:

CREATE TABLE Student
(
Admno integer NOT NULL UNIQUE → Unique constraint
Name char (20) NOT NULL,
Gender char (1),
Age integer,
Place char (10),
);

The UNIQUE constraint can be applied only to fields that have also been declared as NOT NULL.

When two constraints are applied on a single field, it is known as multiple constraints. In the above Multiple constraints NOT NULL and UNIQUE are applied on a single field Admno, the constraints are separated by a space and at the end of the field definition a comma(,) is added. By adding these two constraints the field Admno must take some value i.e. will not be NULL and should not be duplicated.

(II) Primary Key Constraint:
This constraint declares a field as a Primary key which helps to uniquely identify a record. It is similar to unique constraint except that only one field of a table can be set as primary key. The primary key does not allow NULL values and therefore a field declared as primary key must have the NOT NULL constraint.
Example showing Primary Key Constraint in the student table:
CREATE TABLE Student
(
Admno integer NOT NULL PRIMARY KEY, → Primary Key constraint
Name char(20)NOT NULL,
Gender char(I),
Age integer,
Place char(10),
);

In the above example the Admno field has been set as primary key and therefore will help us to uniquely identify a record, it is also set NOT NULL, therefore this field value cannot be empty,

(III) DEFAULT Constraint:
The DEFA ULT constraint is used to assign a default value for the field. When no value is given for the specified field having DEFA ULT constraint, automatically the default value will be assigned to the field.
Example showing DEFAULT Constraint in the student table:
CREATE TABLE Student
(
Admno integer NOT NULL PRIMARY KEY,
Name char(20) NOT NULL,
Gender char(1),
Age integer DEFAULT = “17”, → Default Constraint Place char(10),
); –
In the above example the “Age” field is assigned a default value of 17, therefore when no
value is entered in age by the user, it automatically assigns 17 to Age.

(IV) Check Constraint:
This constraint helps to set a limit value placed for a field. When we define a check constraint on a single column, it allows only the restricted values on that field.
Example showing check constraint in the student table:
CREATE TABLE Student
(
Admno integer NOT NULL PRIMARY KEY
Name char(20)NOT NULL,
Gender char(1),
Age integer (CHECK<=19), → Check Constraint Place char(10),
);
In the above example the check constraint is set to Age field where the value of Age must be less than or equal to 19.

Note:
The check constraint may use relational and logical operators for condition.

(V) TABLE CONSTRAINT:
When the constraint is applied to a group of fields of the table, it is known as Table constraint. The table constraint is normally given at the end of the table definition. Let us take a new table namely Student 1 with the following fields Admno, Firstname, Lastname, Gender, Age, Place:

CREATE TABLE Student 1
(
Admno integer NOT NULL,
Firstname char(20),
Lastname char(20),
Gender char(1),
Age integer,
Place char(10),
PRIMARY KEY (Firstname, Lastname) → Table constraint
);
In the above example, the two fields, Firstname and Lastname are defined as Primary key which is a Table constraint.

PART – II

Answer any six questions. Question No. 21 is compulsory. [6 × 2 = 12]

Question 16.
Write note on keyword argument?
Answer:
Keyword arguments will invoke the function after the parameters are recognized by their parameter names. The value of the keyword argument is matched with the parameter name and so, one can also put arguments in improper order (not in order).

Question 17.
What is composition in functions?
Answer:
The value returned by a function may be used as an argument for another function in a nested manner. This is called composition. For example, if we wish to take a numeric value or an expression as a input from the user, we take the input string from the user using the function input( ) and apply eval( ) function to evaluate its value.

Question 18.
Write note on len (str)?
Answer:
Syntax : len(str)
Description: Returns the length (no of characters) of the string.
Example: >>> A=”Corporation”
>>> print(len(A))
11

Question 19.
Define sequence data type?
Answer:
Python programming language has four collections of data types such as List, Tuples, Set – and Dictionary. A list in Python is known as a “sequence data type” like strings. It is an ordered collection of values enclosed within square brackets [ ].

Question 20.
Give example for modifying variable outside a function?
Answer:
Example:
let y: = 0
(int) inc (int) x
y: = y + x;
return (y)

Question 21.
Define ADT?
Answer:
Abstract Data type (ADT) is a type (or class) for objects whose behavior is defined by a set of value and a set of operations.

Question 22.
Write note on Boolean data type?
Answer:
A Boolean data can have any of the two values: True or False.
Example :
Bool_varl=True
Bool_var2=False

2. Keyword variable arguments

PART – III

Answer any six questions. Question No. 29 is compulsory. [6 × 3 = 18]

Question 25.
Explain print ( ) in python?
Answer:
In Python, the print( ) function is used to display result on the screen. The syntax for print( ) is as follows:
Example:
print (“string to be displayed as output ”) print (variable)
print (“String to be displayed as output ”, variable)
print (“Stringl ”, variable, “String 2”, variable, “String 3” )

Question 26.
Give the rules for variables?
Answer:
An Identifier is a name used to identify a variable, function, class, module or object.

1. An identifier must start with an alphabet (A..Z or a..z) or underscore (_).
2. Identifiers may contain digits (0 .. 9)
3. Python identifiers are case sensitive, i.e., uppercase and lowercase letters are distinct.
4. Identifiers must not be a python keyword.
5. Python does not allow punctuation character such as %,$, @ etc., within identifiers.

Question 27.
Explain commands and their functions in SQL?
Answer:
Tables are the only way to store data, therefore all the information has to be arranged in the form of tables. The SQL provides a predetermined set of commands to work on databases.

Keywords:
They have a special meaning in SQL. They are understood as instructions.

Commands:
They are instructions given by the user to the database also known as statements.

Clauses:
They begin with a keyword and consist of keyword and argument.

Arguments:
They are the values given to make the clause complete.

Question 28.
Write note on abs ( ), Ord ( ), Chr ( )?
Answer:

Question 29.
Write a pure function to find Gcd of 2 numbers?
Answer:
let rec gcd a b :=
if b < > 0 then gcd b (a mod b) else return a;;
output
gcd 13 27;;
-: int = 1
gcd 20536 7826;;
-: int = 2
In the above example program ‘gcd’ is the name of the function which recursively called till the variable ‘b’ becomes ‘O’. Remember b and (a mod b) are two arguments passed to ‘a’ and ‘b’of the gcd function.

Question 30.
Write the use of Savepoint command with an example?
Answer:
SAVEPOINT command:
The SAVEPOINT command is used to temporarily save a transaction so that you can rollback to the point whenever required. The different states of our table can be saved at anytime using different names and the rollback to that state can be done using the ROLLBACK command.

3. Modules can be included in a program.
4. Module segments can be used by invoking a name and some parameters.
5. Module segments can be used by other modules.

[OR]

(b) Explain Alter command in SQL?
Answer:
The ALTER command is used to alter the table structure like adding a column, renaming the existing column, change the data type of any column or size of the column or delete the column from the table. It is used in the following way:

ALTER TABLE <table-name> ADD <column-name> <data type> <size>;
To add a new column “Address” of type ‘char’ to the Student table, the command is used as:-

ALTER TABLE Student ADD Address char;
To modify existing column of table, the ALTER TABLE command can be used with MODIFY clause like wise:

ALTER <table-name> MODIFY<column-name> <data type> <size>;
ALTER TABLE Student MODIFY Address char (25);

The above command will modify the address column of the Student table to now hold 25 characters. The ALTER command can be used to rename an existing column in the following way:

ALTER <table-name> RENAME old-column-name TO new-column-name;
For example to rename the column Address to City, the command is used as:

ALTER TABLE Student RENAME Address TO City;
The ALTER command can also be used to remove a column or all columns, for example to remove a particular column, the DROP COLUMN is used with the ALTER TABLE to remove a particular field, the command can be used as:

ALTER <table-name> DROP COLUMN <column-name>;
To remove the column City from the Student table, the command is used as:
ALTER TABLE Student DROP COLUMN City;

Question 36(a).
Consider the following employee table. Write SQL commands for the qtns.(i) to (v)?

1. To display the details of all employees in descending order of pay.
2. To display all employees whose allowance is between 5000 and 7000.
3. To remove the employees who are mechanic.
4. To add a new row.
5. To display the details of all employees who are operators.

Answer:
Output:

1. SELECT * FROM employee ORDER BY DESC;
2. SELECT * FROM employee WHERE ((allowance >= 5000) AND (allowance <=7000));
3. DELETE FROM employee WHERE desig = “Mechanic”;
4. INSERT INTO employee(Empcode, Name, desig, pay, allowance) VALUES(‘M1006’, ‘RAM’, ‘Mechanic’,22000, 8000);
5. SELECT * FROM employee WHERE desig = ‘operator’;

[OR]

(b) How will you write data into different types in CSV files?
Answer:
As you know Python provides an easy way to work with CSV file and has csv module to read and write data in the csv file. In the previous topics, You have learned how to read CSV files • in Python. In similar way, You can also write a new or edit an existing CSV files in Python.

1. Creating A New Normal CSV File
2. Modifying An Existing File
3. Writing On A CSV File with Quotes
4. Writing On A CSV File with Custom Delimiters
5. Writing On A CSV File with Lineterminator
6. Writing On A CSV File with Quotechars
7. Writing CSV File Into A Dictionary
8. Getting Data At Runtime And Writing In a File

Question 37 (a).
Write a sample program to illustrate private and public variables using classes?
Answer:
class Sample:
def_init_(self, n1, n2):
self._n1=n1
self._n2=n2
def display(self):
print(“Class variable 1 = “, self.n1)
print(“Class variable 2 = “, self._n2)
S=Sample(12, 14)
S.display( )
print(“Value 1 = “, S.n1)
print(“Value 2 = “, S._n2)
In the above program, there are two class variables n1 and n2 are declared. The variable nl is a public variable and n2 is a private variable. The display( ) member method is defined to show the values passed to these two variables.

The print statements defined within class will successfully display the values of n1 and n2, even though the class variable n2 is private. Because, in this case, n2 is called by a method defined inside the class. But, when we try to access the value of n2 from outside the class Python throws an error. Because, private variable cannot be accessed from outside the class.

Output:
Class variable 1 = 12 Class variable 2=14 Value 1 = 12
Traceback (most recent call last):
File “D:/Python/Class-Test-04.py”, line 12, in <module> print(“Value 2 = “, S._n2)
AttributeError: ‘Sample’ object has no attribute ‘n2’

[OR]

(b) Explain updating and deleting Tuple with example?
Answer:
As you know a tuple is immutable, the elements in a tuple cannot be changed. Instead of altering values in a tuple, joining two tuples or deleting the entire tuple is possible.
Example:
# Program to join two tuples
Tup 1 = (2, 4, 6, 8, 10)
Tup 2 = (1,3,5,7,9)
Tup 3 = Tup1 + Tup2
print(Tup3)

Output:
(2, 4, 6, 8, 10, 1, 3, 5, 7, 9)
To delete an entire tuple, the del command can be used.
Syntax: del tuple_name
Example:
Tup1 =(2, 4, 6, 8, 10)
print(“The elements of Tup1 is “, Tup1)
del Tup1
print (Tup1)

Output:
The elements of Tupl is (2, 4, 6, 8, 10)
Traceback (most recent call last):
File “D:/Python/Tuple Examp l.py”, line 4, in <module>
print (Tupl)
NameError: name ‘Tup1’ is not defined
Note that, the print statement in the above code prints the elements. Then, the del statement deletes the entire tuple. When you try to print the deleted tuple, Python shows the error.

Question 38 (a).
Explain nested If -elif – else statement with example?
Answer:
When we need to construct a chain of if statement(s) then ‘elif’ clause can be used instead of ‘else’.
Syntax:
if <condition-l>:
statements-block 1

elif <condition-2>:
statements-block 2

else:
statements-block n

In the syntax of if.elifi.else mentioned above, condition-1 is tested if it is true then statements- block 1 is executed, otherwise the control checks . condition-2, if it is true statements-block2 is executed and even if it fails statements-block n mentioned in else part is executed.

‘elif’ clause combines ifi.else-ifi.else statements to one if..elif…else, ‘elif’ can be considered to be abbreviation of ‘else if’. In an ‘if’ statement there is no limit of ‘elif’ clause that can be used, but an ‘else’ clause if used should be placed at the end.

Example:
Program to illustrate the use of nested if statement

m1=int (input(“Enter mark in first subject: ”))
m2=int (input(“Enter mark in second subject: ”))
avg= (m1+m2)/2
if avg>=80:
print (“Grade : A”)
elif avg>=70 and avg<80:
print (“Grade : B”)
elif avg>=60 and avg<70:
print (“Grade : C”)
elif avg>=50 and avg<60:
print (“Grade : D”)
else:
print (“Grade : E”)

Output 1:
Enter mark in first subject: 34 Enter mark in second subject: 78 Grade : D

Output 2 :
Enter mark in first subject: 67

[OR]

(b) Explain how to pass parameters in functions?
Answer:
Parameters or arguments can be passed to functions:-

deffunction_name (parameters) separated by comma):

Let us see the use of parameters while defining functions. The parameters that you place in the parenthesis will be used by the function itself. You can pass all sorts of data to the functions. Here is an example program that defines a function that helps to pass parameters into the function.

# assume w = 3 and h = 5
def area(w,h):
return w * h
print (area (3,5))

The above code assigns the width and height values to the parameters w and h. These parameters are used in the creation of the function “area”. When you call the above function, it returns the product of width and height as output. The value of 3 and 5 are passed to w and h respectively, the function will return 15 as output.

In python, a set is another type of collection data type. A Set is a mutable and an unordered collection of elements without duplicates. That means the elements within a set cannot be repeated. This feature used to include membership testing and eliminating duplicate elements.

Question 20.
Write note on self?
Answer:
The class method must have the first argument named as self. No need to pass a value for this argument when we Call the method. Python provides its value automatically.

Even if a method takes no arguments, it should be defined with the first argument called self. If a method is defined to accept only one argument it will take it as two arguments i.e. self and the defined argument.

What are the advantages of Tuples over a list?
Answer:

1. The elements of a list are changeable (mutable) whereas the elements of a tuple are unchangeable (immutable), this is the key difference between tuples and list.
2. The elements of a list are enclosed within square brackets. But, the elements of a tuple are enclosed by paranthesis.
3. Iterating tuples is faster than list.

Question 31.
How will you create a set in python?

PART – IV

Answer all the questions. [5 × 5 = 25]

Question 34(a).
Explain the concept of Dynamic programming with suitable example?
Answer:
Dynamic programming:
Dynamic programming is an algorithmic design method that can be used when the solution to a problem can be viewed as the result of a sequence of decisions.

Dynamic programming approach is similar to divide and conquer. The given problem is divided into smaller and yet smaller possible sub-problems.

Dynamic programming is used whenever problems can be divided into similar sub-problems. So that their results can be re-used to complete the process.

Dynamic programming approaches are used to find the solution in optimized way. For every inner sub problem, dynamic algorithm will try to check the results of the previously solved sub-problems. The solutions of overlapped sub-problems are combined in order to get the better solution.

Steps to do Dynamic programming

• The given problem will be divided into smaller overlapping sub-problems.
• An optimum solution for the given problem can be achieved by using result of smaller sub-problem.
• Dynamic algorithms uses Memoization.

Fibonacci Series – An example:
Fibonacci series generates the subsequent number by adding two previous numbers. Fibonacci series starts from two numbers – Fib 0 & Fib 1. The initial values of fibO & fibl can be taken as 0 and 1.
Fibonacci series satisfies the following conditions:
Fibn = Fib_n-1 + Fib_n-2

Hence, a Fibonacci series for the n value 8 can look like this
Fib8 = 0 1 1 2 3 5 8 13

Fibonacci Iterative Algorithm with Dynamic programming approach

The following example shows a simple Dynamic programming approach for the generation of Fibonacci series.
Initialize f0 = 0, f1 =1

step-1: Print the initial values of Fibonacci f0 and f1
step-2: Calculate fibonacci fib ← f0 + f1
step-3: Assign f0 ← f1, f1 ← fib
step-4: Print the next consecutive value of fibanocci fib
step-5: Goto step-2 and repeat until the specified number of terms generated.

For example if we generate fibanocci series up to 10 digits, the algorithm will generate the series as shown below:
The Fibonacci series is : 0 1 1 2 3 5 8 13 21 34 55

[OR]

(b) List out the set operations supported by python?
Answer:
(I) Union:
It includes all elements from two or more sets.
In python, the operator | is used to union of two sets. The function union( ) is also used to join two sets in python.

Example: Program to Join (Union) two sets using union operator
set_A={2,4,6,8}
set_B={‘A’, ‘B’, ’C, ’D’}
U_set=set_A|set_B
print(U_set)
Output:
{2, 4, 6, 8, ‘A’, ‘D’, ‘C’, ‘B’}

(II) Intersection:
It includes the common elements in two sets
The operator & is used to intersect two sets in python. The function intersection ( ) is also used to intersect two sets in python.
Example: Program to insect two sets using intersection operator
set_A={‘A’, 2, 4, ‘D’}
set_B={‘A’, ‘B’, ‘C’, ‘D’}
print(set_A & set_B)
Output:
{A’, ‘D’}

(III) Difference:
It includes all elements that are in first set (say set A) but not in the second set (say set B)
The minus (-) operator is used to difference set operation in python.
The function difference() is also used to difference operation.
Example: Program to difference of two sets using minus operator
set_A={A’, 2, 4, ‘D’}
set_B={‘A’, ‘B’, ‘C’, ‘D’}
print(set_A – set_B)
Output:
{2,4}

(IV) Symmetric difference:
It includes all the elements that are in two sets (say sets A and B) but not the one that are common to two sets.
The caret (^) operator is used to symmetric difference set operation in python. The function symmetric_difference( ) is also used to do the same operation.
Example: Program to symmetric difference of two sets using caret operator
set_A={‘A’, 2, 4, ‘D’}
set_B={‘A’, ‘B’, ‘C’, ‘D’}
print(set_A ^ set_B)
Output:
(2, 4, ’B’, ‘C’}

Question 35(a).

m=int(input(“Enter Mark = “))
marks.append(m)
for j in range(len(marks)):
print(“{ }. { } Mark= { } “.format(j1+,subjects[j],marks[j]))
print(“Total Marks = “, sum(marks))

Output
Enter Mark = 45
Enter Mark = 98
Enter Mark = 76
Enter Mark = 28
Enter Mark = 46
Enter Mark = 15

1. Tamil Mark = 45
2. English Mark = 98
3. Physics Mark = 76
4. Chemistry Mark = 28
5. Comp. Science Mark = 46

Age integer,
Place char(10),
);

(b) ALTER COMMAND:
The ALTER command is used to alter the table structure like adding a column, renaming the existing column, change the data type of any column or size of the column or delete the column from the table. Alter table Student add address char;

(c) DROP TABLE:
Drop table command is used to remove a table from the database.
DROP TABLE Student;

Question 37 (a).

2. It gives a unique name to each data item type, record type, file type and data base.
3. It should specify the proper data type.
4. It should define the size of the data item.
5. It may define the range of values that a data item may use.
6. It may specify privacy locks for preventing unauthorized data entry.

[OR]

(b) Write the different methods to read a File in Python? Read a CSV File Using Python?
Answer:
There are two ways to read a CSV file.

1. Use the csv module’s reader function
2. Use the DictReader class.

(I) CSV Module’s Reader Function:
You can read the contents of CSV file with the help of csv.reader( ) method. The reader function is designed to take each line of the file and make a list of all columns. Then, you just choose the column you want the variable data for. Using this method one can read data from csv files of different formats like quotes (” “),pipe (|) and comma(,).

The syntax for csv.reader( ) is
csv. readert(fileobject, delimiter,fmtparams)

where:-
File object:- passes the path and the mode of the file
Delimiter:- An optional parameter containing the standard dilects like, I etc can be omitted.
Fmtparams:- Optional parameter which help to override the default values of the dialects like skipinitialspace,quoting etc can be omitted.

(II) Reading CSV File Into A Dictionary:
To read a CSV file into a dictionary can be done by using DictReader class of csv module which works similar to the reader( ) class but creates an object which maps data to a dictionary.

The keys are given by the fieldnames as parameter. DictReader works by reading the first line of the CSV and using each comma separated value in this line as a dictionary key. The columns in each subsequent row then behave like dictionary values and can be accessed with the appropriate key (i.e. fieldname).

If the first row of your CSV does not contain your column names, you can pass a fieldnames parameter into the DictReader’s constructor to assign the dictionary keys manually.

The main difference between the csv.reader( ) and DictReader( ) is in simple terms csv. reader and csv. writer work with list/tuple, while csv.DictReader and csv.DictWriter work with dictionary. csv.DictReader and csv.DictWriter take additional argument fieldnames that are used as dictionary keys.

Question 38 (a).
Write a python program to read a csv file and store it in a list? Read A CSV File And Store It In A List?
Answer:
In this topic you are going to read a CSV file and the contents of the file will be stored as a list. The syntax for storing in the List is
list = [ ]                           # Start as the empty list
list.append(element)      # Use append( ) to add elements
For example all the row values of “sample.csv” file is stored in a list using the following
program
import csv
# other way of declaring the filename
inFile= ‘c:\ \pyprg\\sample.csv’
F=open(inFile,’r’)
reader= csv.reader(F)
# declaring array array Value = [ ]
# displaying the content of the list for row in reader:
array Value.append(row)
print(row)
F.close( )

[OR]

(b) Explain OR, AND and NOT operator in SQL?
Answer:
The WHERE clause can be combined with AND, OR, and NOT operators. The AND and OR operators are used to filter records based on more than one condition. In this example you
are going to display the details of students who have scored other than ‘A’. or ‘B’ from the “student table”

Example for WHERE WITH NOT Operator
import sqlite3
connection= sqlite3 ,connect(” Academy.db”)
cursor = connection.cursor( )
cursor.execute(“SELECT *FROM student where grade< >’A’ and Grade< >’B'”)
result = cursor. fetchall( )
print(*result,sep=”\n”)

OUTPUT
(3, ’BASKAR’, ‘C, ‘M’, 75.2, ‘1998-05-17’)
(7, ‘TARUN’, ’D’, ‘M’, 62.3, ‘1999-02-01’)

Example for WHERE WITH AND Operator:-
In this example we are going to display the name, Rollno and Average of students who have scored an average between 80 to 90% (both limits are inclusive) import sqlite3
connection = sqlite3.connect(” Academy.db”)
cursor = connection.cursor( )
cursor.execute(“SELECT Rollno, Same, Average FROM student WHERE (Average>=80 AND Average<=90)”)
result = cursor. fetchall( )
print(*result,sep=”\n”)

OUTPUT
(1, ’Akshay’, 87.8)
(5, ’VARUN’, 80.6)

Example for WHERE WITH OR Operator:-
In this example we are going to display the name and Rollno of students who have not scored an average between 60 to 70% import sqlite3
connection = sqlite3.connect(” Academy.db”)
cursor = connection.cursor( )
cursor.execute(“SELECT Rollno,sname FROM student WHERE (Average<60 OR
Average> 70)”)
result = cursor. fetchall( )
print(*result,sep=”\n”)

OUTPUT
(1, ‘Akshay’)
(2, ‘Aravind’)
(3, ‘BASKAR’)
(4, ‘SAJINI’)
(5, ‘VARUN’)
(6, ‘PRIYA’)

Question 31.
Define list. How will you represent rational numbers with list?
Answer:
List is constructed by placing expressions within square brackets separated by commas. Such an expression is called a list literal. List can store multiple values. Each value can be of any type and can even be another list. Example for List is [10, 20].

Representing Rational Numbers Using List:
You can now represent a rational number as a pair of two integers in pseudo code: a numerator and a denominator
rational(n, d):

Question 34 (a).
Explain the pseudo code to do Binary search?
Answer:
(I) Start with the middle element:

• If the search element is equal to the middle element of the array i.e., the middle value = number of elements in array/2, then return the index of the middle element.
• If not, then compare the middle element with the search value.
• If the search element is greater than the number in the middle index, then select the elements to the right side of the middle index, and go to Step-1.
• If the search element is less than the number in the middle index, then select the elements to the left side of the middle index, and start with Step-1.

(II) When a match is found, display success message with the index of the element matched.

(III) If no match is found for all comparisons, then display unsuccessful message.

[OR]

(b) Give the pseudo code for insertion sort?
Answer:
Step 1 – If it is the first element, it is already sorted.
Step 2 – Pick next element.
Step 3 – Compare with all elements in the sorted sub-list.
Step 4 – Shift all the elements in the sorted sub-list that is greater than the value to be sorted
Step 5 – Insert the value
Step 6 – Repeat until list is sorted

Question 35 (a).
Explain input function with example?
input( ) function:
Answer:
In Python, input( ) function is used to accept data as input at run time. The syntax for input( ) function is,
Variable = input (“prompt string ’’)

Where, prompt string in the syntax is a statement or message to the user, to know what input can be given. If a prompt string is used, it is displayed on the monitor; the user can provide expected data from the input device. The input( ) takes whatever is typed from the keyboard and stores the entered data in the given variable. If prompt string is not given in input( ) no message is displayed on the screen, thus, the user will not know what is to be typed as input.

Example: input( ) with prompt string
>>> city=input (“Enter Your City: ”)
Enter Your City: Madurai
>>> print (“I am from”, city)
I am from Madurai

Example: input( ) without prompt string
>>> city=input( )
Rajarajan
>>> print (“I am from”, city)
I am from Rajarajan

Note that in example-2, the input( ) is not having any prompt string, thus the user will not know what is to be typed as input. If the user inputs irrelevant data as given in the above example, then the output will be unexpected. So, to make your program more interactive, provide prompt string with input( ).

The input ( ) accepts all data as string or characters but not as numbers. If a numerical value is entered, the input values should be explicitly converted into numeric data type.

The int ( ) function is used to convert string data as integer data explicitly. We will learn about more such functions in later chapters.

Example:
x = int (input(“Enter Number 1: ”))
y = int (input(“Enter Number 2: ”))
print (“The sum = ”, x+y)
Output:
Enter Number 1 : 34
Enter Number 2 : 56
The sum = 90

Example: Alternate method for the above program
x,y=int (input(“Enter Number 1 :”)),int(input(“Enter Number 2:”))
print (“X = “,x,” Y = “,y)
Output:
Enter Number 1:30
Enter Number 2:50
X = 30 Y = 50

[OR]

(b) Explain various types of Relationships in dBMS?
Answer:
Following are the types of relationships used in a database.

1. One-to-One Relationship
2. One-to-Many Relationship
3. Many-to-One Relationship
4. Many-to-Many Relationship

1. One-to-One Relationship
In One-to-One Relationship, one entity is related with only one other entity. One row in a table is linked with only one row in another table and vice versa.
For example: A student can have only one exam number

2. One-to-Many Relationship
In One-to-Many relationship, one entity is related to many other entities.
One row in a table A is linked to many rows in a table B, but one row in a table B is linked to only one row in table A.
For example: One Department has many staff members.

3. Many-to-One Relationship
In Many-to-One Relationship, many entities can be related with only one in the other entity. For example: A number of staff members working in one Department.
Multiple rows in staff members table is related with only one row in Department table.

4. Many-to-Many Relationship
A many-to-many relationship occurs when multiple records in a table are associated with multiple records in another table.

Example 1: Customers and Product
Customers can purchase various products and Products can be purchased by many customers.

Example 2: Students and Courses A student can register for many Courses and a Course may include many students.

Example 3: Books and Student.
Many Books in a Library are issued to many students.

Question 36 (a).

Question 37(a).
Explain python getopt module?
Answer:
The getopt module of Python helps you to parse (split) command-line options and arguments. This module provides two functions to enable command-line argument parsing.
getopt.getopt method
This method parses command-line options and parameter list. Following is the syntax for this method –
<opts> ,<args>=getopt.getopt (argv, options, [long options])
Here is the detail of the parameters –

argv – This is the argument list of values to be parsed (splited). In our program the complete command will be passed as a list.
options – This is string of option letters that the Python program recognize as, for input or for output, with options (like ‘i’ or ‘o’) that followed by a colon (:). Here colon is used to denote the mode.

longoptions – This parameter is passed with a list of strings. Argument of Long options should be followed by an equal sign (‘=’). In our program the C++ file name will be passed as string and ‘i’ also will be passed along with to indicate it as the input file.

getopt( ) method returns value consisting of two elements. Each of these values are stored separately in two different list (arrays) opts and args. Opts contains list of splitted strings like mode, path and args contains any string if at all not splitted because of wrong path or mode. args will be an empty array if there is no error in splitting strings by getopt( ).

For example The Python code which is going to execute the C++ file p4 in command line will have the getopt() method like the following one.
opts, args = getopt.getopt (argv, “i:”,[‘ifile=’])

In our examples since the entire command line commands are parsed and no leftover argument, the second argument args will be empty [ ]. If args is displayed using print( ) command it displays the output as [ ].
>>>print(args)
[ ]

[OR]

(b) Write a sql code using where clause to display the different grades scored by male students from student table?
Answer:
The WHERE clause is used to extract only those records that fulfill a specified condition. In this example we are going to display the different grades scored by male students from “student table” import sqlite3
connection = sqlite3.connect(“Academy.db”)
cursor = connection.cursor( )
cursor.execute(” SELECT DISTINCT (Grade) FROM student where gender=’M”‘)
result = cursor.fetchall( )
print(*result,sep=”\n”)
OUTPUT
(‘B’,)
(‘A’,)
(C’,)
(D’,)

Question 38 (a).
Write a program that accept data using python input ( ) command and write it in the Table called person?
Answer:
In this example we are going to accept data using Python input() command during runtime and then going to write in the Table called “Person”

Example:
# code for executing query using input data import sqlite3
# creates a database in RAM
con =sqlite3.connect(” Academy, db”)
cur =con.cursor( )
cur.execute(“DROP Table person”)
cur.execute(“create table person (name, age, id)”)
print(“Enter 5 students names:”)
who =[input( ) for i in range(5)]
print(“Enter their ages respectively:”)
age =[int(input()) for i in range(5)]
print(“Enter their ids respectively:”)
p_id =[int(input())for i in range(5)]
n =len(who)
for i in range(n):
# This is the q-mark style:
cur.execute(“insert into person values (?, ?, ?)”, (who[i], age[i], p_id[i]))
# And this is the named style: cur.execute(“select * from person”)
# Fetches all entries from table
print(“Displaying All the Records From Person Table”)
print (*cur.fetchall( ), sep-\n’)

Output:
Enter 5 students names:
RAM
KEERTHANA
KRISHNA
HARISH
GIRISH

Enter their ages respectively:
28
12
21

Enter their ids respectively:
1
2
3
4
5

Displaying All the Records From Person Table
(‘RAM’, 28, 1)
(’KEERTHANA’, 12, 2)
(’KRISHNA1, 21,3)
(‘HARISH’, 18,4)
(‘GIRISH’, 16, 5)

You can even add records to the already existing table like “Student” Using the above coding with appropriate modification in the Field Name. To do so you should comment the create table statement

[OR]

(b) Write a CSV file with a line terminator?
Answer:
A Line Terminator is a string used to terminate lines produced by writer. The default value is \r or \n. We can write csv file with a line terminator in Python by registering new dialects using csv.register_dialect( ) class of csv module.
For Example
import csv
Data = [[‘Fruit’, ‘Quantity’], [‘Apple’, ‘5’], [‘Banana’, ‘7’], [‘Mango’, ‘8’]]
csv.register_dialect(‘myDialect’, delimiter = ‘|’, lineterminator = ‘\n’)
with open(‘c:\\pyprg\\chl3\\line.csv’, ‘w’) as f:
writer = csv.writer(f, dialect=‘myDialect’)
writer.writerows(Data)
f.close( )
When we open the line.csv file, we get following output with spacing between lines:

In the above code, the new dialect “myDialect uses the delimiter=‘|’ where a | (pipe) is considered as column separator. The line terminator=‘\r\n\r\n’ separates each row and display the data after every two lines.

PART – IV

Answer all the questions. [7 × 5 = 35]

Question 41 (a).
Briefly explain the objective factors of consumption functions.
Answer:
Objective Factors:
(i) Income Distribution:
If there is large disparity between rich and poor, the consumption is low because the rich people have low propensity to consume and high propensity to save.

(ii) Price level:

• Price level plays an important role in determining the consumption function.
• When the price falls, real income goes up; people will consume more and propensity to save of the society increases.

(iii) Wage level:

• Wage level plays an important role in determining the consumption function and there is positive relationship between wage and consumption.
• Consumption expenditure increases with the rise in wages.
• Similar is the effect with regard to windfall gains.

(iv) Interest rate:

• Rate of interest plays an important role in determining the consumption function.
• Higher rate of interest will encourage people to save more money and reduces consumption.

(v) Fiscal Policy:
When government reduces the tax the disposable income rises and the propensity to consume of community increases.

(vi) Consumer credit:

• The availability of consumer credit at easy installments will encourage households to buy consumer durables like automobiles, fridge, computer.
• This pushes up consumption.

(vii) Demographic factors:

• Ceteris paribus, the larger the size of the family, the grater is the consumption.
• Besides size of family, stage in family life cycle, place of residence and occupation affect the consumption function.

(viii) Duesenberry hypothesis:
Duesenberry has made two observations regarding the factors affecting consumption.

• The consumption expenditure depends not only on his current income but also past income and standard of living.
• Consumption is influenced by demonstration effect. The consumption standards of low income groups are influenced by the consumption standards of high income groups..

(ix) Windfall Gains or losses:
Unexpected changes in the stock market leading to gains or losses tend to shift the consumption function upward or downward.

[OR]

(b) Explain the keynes psycological law of consumption asumptions.
Answer:
Keynes’s Law is based on the following assumptions:
(i) Ceteris paribus (constant extraneous variables):
The other variables such as income distribution, tastes, habits, social customs, price movements, population growth, etc. do not change and consumption depends on income alone.

(ii) Existence of Normal Conditions:

• The law holds good under normal conditions.
• If, however, the economy is faced with abnormal and extraordinary circumstances like war, revolution or hyperinflation, the law will not operate.
• People may spend the whole of increased income on consumption.

(iii) Existence of a Laissez-faire Capitalist Economy:

• The law operates in a rich capitalist economy where there is no government intervention.
• People should be free to spend increased income.
• In the case of regulation of private enterprise and consumption expenditures by the State, the law breaks down.

Question 42 (a).
What are the effects of Inflation on the Economy?
Answer:
The effects of inflation can be classified into two heads:

1. Effects on Production and
2. Effects on Distribution.

1. Effects on Production:
When the inflation is veiy moderate, it acts as an incentive to traders and producers. This is particularly prior to full employment when resources are not fully utilized. The profit due to rising prices encourages and induces business class to increase their investments in production, leading to generation of employment and income.

• However, hyper-inflation results in a serious depreciation of the value of money.
• When the value of money undergoes considerable depreciation, this may even drain out the foreign capital already invested in the country.
• With reduced capital accumulation, the investment will suffer a serious set-back which may have an adverse effect on the volume of production in the country.
• Inflation also leads to hoarding of essential goods both by the traders as well as the consumers and thus leading to still higher inflation rate.
• Inflation encourages investment in speculative activities rather than productive purposes.

2. Effects on Distribution:

• Debtors and Creditors: During inflation, debtors are the gainers while the creditors are losers.
• Fixed-income Groups: The fixed income groups are the worst hit during inflation because their incomes being fixed do not bear any relationship with the rising cost of living.
• Entrepreneurs: Inflation is the boon to the entrepreneurs whether they are manufacturers, traders, merchants or businessmen, because it serves as a tonic for business enterprise.
• Investors: The investors, who generally invest in fixed interest yielding bonds and securities have much to lose during inflation.

2. A free trade area is the region encompassing a trade bloc whose member countries have signed a free-trade agreement (FTA). Such agreements involve cooperation between at least two countries to reduce trade barriers, e.g. SAFTA, EFTA.

3. A customs union is defined as a type of trade block which is composed of a free trade area with no tariff among members and (zero tariffs among members) with a common external tariff, e.g. BENELUX (Belgium, Netherland and Luxumbuarg).

4. Common market is established through trade pacts. A group formed by countries within a geographical area to promote duty free trade and free movement of labour and capital among its members, e.g. European Common Market (ECM).

5. An economic union is composed of a common market with a customs union. The participant countries have both common policies on product regulation, freedom of movement of goods, services and the factors of production and a common external trade policy, (e.g. European Economic Union).

Question 45 (a).
Explain the methods of debt redemption.
Answer:
The process of repaying a public debt is called redemption. The Government sells securities to the public and at the time of maturity, the person who holds the security surrenders it to the Government. The following methods are adopted for debt redemption.
(i) Sinking Fund:

• Under this method, the Government establishes a separate fund known as “Sinking Fund”.
• The Government credits every year a fixed amount of money to this fund.
• By the time the debt matures, the fund accumulates enough amount to pay off the principal along with interest.
• This method was first introduced in England by Walpol.

(ii) Conversion:

• Conversion of loans is another method of redemption of public debt.
• It means that an old loan is converted into a new loan.
• Under this system a high interest public debt is converted into a low interest public debt.
• Dalton felt that debt conversion actually relaxes the debt burden.

(iii) Budgetary Surplus:

• When the Government presents surplus budget, it can be utilised for repaying the debt.
• Surplus occurs when public revenue exceeds the public expenditure.
• However, this method is rarely possible.

(iv) Terminal Annuity:

• In this method, Government pays off the public debt on the basis of terminal annuity in
  equal annual installments. .
• This is the easiest way of paying off the public debt.

(v) Repudiation:

• It is the easiest way for the Government to get rid of the burden of payment of a loan.
• In such cases, the Government does not recognise its obligation to repay the loan.
• It is certainly not paying off a loan but destroying it.
• However, in normal case the Government does not do so; if done it will lose its credibility.

(vi) Reduction in Rate of Interest:
Another method of debt redemption is the compulsory reduction in the rate of interest, during the time of financial crisis.

(vi) Capital Levy:

1. When the Government imposes levy on the capital assets owned by an individual or any institution, it is called capital levy.
2. This levy is imposed on capital assets above a minimum limit on a progressive scale.
3. The fund so collected can be used by the Government for paying off war time debt obligations.
4. This is the most controversial method of debt repayment.

[OR]

(b) Describe the various types of deficit in budget.
Answer:
The Indian Government budget, budget deficit is of four major types.

1. Revenue Deficit
2. Budget Deficit
3. Fiscal Deficit, and
4. Primary Deficit

1. Revenue Deficit:
It refers to the excess of the government revenue expenditure over revenue receipts. It does not consider capital receipts and capital expenditure. Revenue deficit implies that the government is living beyond its means to conduct day-to-day operations.
Revenue Deficit (RD) = Total Revenue Expenditure (RE) – Total Revenue Receipts (RR) When RE – RR > 0

2. Budget Deficit:
Budget deficit is the difference between total receipts and total expenditure (both revenue and capital)
Budget Deficit = Total Expenditure – Total Revenue

3. Fiscal Deficit:
Fiscal deficit (FD) = Budget deficit + Government’s market borrowings and liabilities

4. Primary Deficit:
Primary deficit is equal to fiscal deficit minus interest payments. It shows the real burden of the government and it does not include the interest burden on loans taken in the past. Thus, primary deficit reflects borrowing requirement of the government exclusive of interest payments.
Primary Deficit (PD) = Fiscal deficit (PD) – Interest Payment (IP)

Question 46 (a).
Briefly explain classification of Public expenditure.
Answer:
Classification of public expenditure are as follows:

• Public expenditure conferring a special benefit on certain people and at the same time common benefit on the entire community, e.g., administration of justice etc.
• Public expenditure directly benefiting particular group of persons and indirectly the entire society, e.g., social security, public welfare, pension, unemployment relief etc.
• Public expenditure conferring a special benefit on some individuals, e.g., subsidy granted to a particular industry.

(ii) Classification on the Basis of Function:
Adam Smith classified public expenditure on the basis of functions of government in the ‘ following main groups:

• Protection Functions: This group includes public expenditure incurred on the security of the citizens, to protect from external invasion and internal disorder, e.g., defence, police, courts etc.
• Commercial Functions: This group includes public expenditure incurred on the development of trade and commerce, e.g., development of means of transport and communication etc.

Question 47 (a).
Write a note on
(a) Climate change and
(b) Acid rain.
Answer:
(a) Climate Change:
The climate change refers to seasonal changes over a long period with respect to the growing accumulation of greenhouse gases in the atmosphere.

Recent studies have shown that human activities since the beginning of the industrial revolution, have contributed to an increase in the concentration of carbon dioxide in the atmosphere by as much as 40%, from about 280 parts per million in the pre-industrial period, to 402 parts per million in 2016, which in turn has led to global warming.

Several parts of the world have already experienced the warming of coastal waters, high temperatures, a marked change in rainfall patterns, and an increased intensity and frequency of storms. Sea levels and temperatures are expected to be rising.

(b) Acid Rain:

1. Acid rain is one of the consequences of air pollution.
2. It occurs when emissions from factories, cars or heating boilers contact with the water in the atmosphere.
3. These emissions contain nitrogen oxides, sulphur dioxide and sulphur trioxide which when mixed with water becomes sulfurous acid, nitric acid and sulfuric acid.
4. This process also occurs by nature through volcanic eruptions.

3. Size of the Market: Large size of the market would stimulate production, increase employment and raise the National per capita income. That is why developed countries expand their market to other countries through WTO.

4. Structural Change: Structural change refers to change in the occupational structure of the economy. Any economy of the country is generally divided into three basic sectors: Primary sector such as agricultural, animal husbandry, forestry, etc; Secondary sector such as industrial production, constructions and Tertiary sector such as trade, banking and commerce.

Question 23.
Define Marginal Propensity to Save (MPS).
Answer:
Marginal Propensity to Save (MPS):
Marginal Propensity to Save is the ratio of change in saving to a change in income. MPS is obtained by dividing change in savings by change in income. It can be expressed algebraically as
MPS = \(\frac{ΔS}{ΔY}\)
ΔS = Change in Saving;
ΔY = Change in Income
Since MPC + MPS = 1
MPS = 1 – MPC and MPC = 1 – MPS

Question 31.
Enumerate the features of mixed economy.
Answer:
Features of Mixed Economy:
1. Ownership of Property and Means of Production: The means of production and properties are owned by both private and public. Public and Private have the right to purchase, use or transfer their resources.

2. Coexistence of Public and Private Sectors: In mixed economies, both private and public sectors coexist. Private industries undertake activities primarily for profit. Public sector firms are owned by the government with a view to maximize social welfare.

3. Economic Planning: The central planning authority prepares the economic plAnswer: National plans are drawn up by the Government and both private and public sectors abide. In general, all sectors of the economy function according to the objectives, priorities and targets laid down in the plan.

4. Solution to Economic Problems: The basic problems of what to produce, how to produce, for whom to produce and how to distribute are solved through the price mechanism as well as state intervention.

5. Freedom and Control: Though private has freedom to own resources, produce goods and services and distribute the same, the overall control on the economic activities rests with the government.

Question 32.
What is the solution to the problem of double counting in the estimation of national income?
Answer:

1. The value obtained is actually the GNP at market prices. Care must be taken to avoid double counting.
2. The value of the final product is derived by the summation of all the values added in the productive process.
3. To avoid double counting, either the value of the final output should be taken into the estimate of GNP or the sum of values added should be taken.
4. Double counting is to be avoided under value added method.
5. Any commodity which is either raw material or intermediate good for the final production should not be included.
6. For example, value of cotton enters value of yam as cost, and value of yam in cloth and that of cloth in garments.
7. At every stage value added only should be calculated.

Question 33.
Mention the expenditure method (or) out-lay method.
Answer:
The Expenditure Method (Outlay method): The total expenditure incurred by the society in a particular year is added together. To calculate the expenditure of a society, it includes personal consumption expenditure, net domestic investment, government expenditure on consumption as well as capital goods and net exports. Symbolically,
GNP = C + I + G + (X – M)
C – Private consumption expenditure
I – Private Investment Expenditure
G – Government expenditure
X – M = Net exports

Question 34.
Discuss the estimating the national income through the Income Method precautions.
Answer:

1. Transfer payments are not to be included in estimation of national income as these payments are not received for any services provided in the current year such as pension, social insurance etc.
2. The receipts from the sale of second hand goods should not be treated as part of national income as they do not create new flow of goods or services in the current year.
3. Windfall gains such as lotteries are also not to be included as they do not represent receipts from any current productive activity.
4. Corporate profit tax should not be separately included as it has been already included as a part of company profit.

Question 35.

5. Farmers are depending on the industrial firm for their seeds.

Question 40.
What is Crony capitalism?
Answer:
Social Organization:

1. People show interest in the development activity only when they feel that the fruits of development will be fairly distributed.
2. Mass participation in development programs is a pre-condition for accelerating the ‘ development process.
3. Whenever the defective social organization allows some groups to appropriate the benefits of growth.
4. Majority of the poor people do not participate in the process of development.
5. This is called crony capitalism.

PART – IV

Answer all the questions. [7 x 5 = 35]

Question 41 (a).
Explain the Aggregate Demand Function with Diagram.
Answer:
In the Keynesian model, output is determined mainly by aggregate demand. The aggregate demand is the amount of money which entrepreneurs expect to get by selling the output produced by the number of labourers employed.

Therefore, it is the expected income or revenue from the sale of output at different levels of employment.
Aggregate demand has the following four components:

1. Consumption demand
2. Investment demand
3. Government expenditure and
4. Net Export (export – import)

The desired or planned demand (spending) is the amount that households, firms, the governments and the foreign purchasers would like to spend on domestic output.

In other words, desired demand in the economy is the sum total of desired private consumption expenditure, desired investment expenditure, desired government spending and desired net exports (difference between exports and imports). Thus, the desired spending is called aggregate spending (demand), and can be expressed as:
AD = C + I + G + (X – M)
The diagram explains that aggregate demand price increases or decreases with an increase or decrease in the volume of employment. Aggregate demand curve increases at an increasing rate in the beginning and then increases at a decreasing rate.

This shows that as income increases owing to increase in employment, expenditure of the economy increases at a decreasing rate.

[OR]

(b) Describe the Effective demand.
Answer:

1. The starting point of Keynes theory of employment and income is the principle of effective demand.
2. Effective demand denotes money actually spent by the people on products of industry.
3. The money which entrepreneurs receive is paid in the form of rent, wages, interest and profit.
4. Therefore effective demand equals national income.
5. An increase in the aggregate effective demand would increase the level of employment.
6. A decline in total effective demand would lead to unemployment.
7. Therefore, total employment of a country can be determined with the help of total demand of a country.
8. According to the Keynes theory of employment, “Effective demand signifies the money spent on consumption of goods and services and on investment.
9. The total expenditure is equal to the national income, which is equivalent to the national output”.
10. The relationship between employment and output of an economy depends upon the level of effective demand which is determined by the forces of aggregate supply and aggregate demand.
    ED = Y = C + I = Output = Employment
11. Effective demand determines the level of employment in the economy.
12. When effective demand increases, employment will increase.
13. When effective demand decreases, the level employment will decline.
14. The effective demand will be determined by two determinants namely consumption and investment expenditures.
15. The consumption function depends upon income of the people and marginal propensity to consume.
16. According to Keynes, if income increases, consumption will also increase but by less than the increase in income.

Question 42 (a).
Illustrate the working of Multiplier.
Answer:
Working of Multiplier:
1. Suppose the Government undertakes investment expenditure equal to Rs 100 crore on some public works, by way of wages, price of materials etc.
2. Thus income of labourers and suppliers of materials increases by Rs 100 crore. Suppose the MPC is 0.8 that is 80 %.
3. A sum of Rs 80 crores is spent on consumption (A sum of Rs 20 Crores is saved).
4. As a result, suppliers of goods get an income of Rs 80 crores.
5. They intum spend Rs 64 crores (80% of Rs 80 cr).
In this manner consumption expenditure and increase in income act in a chain like manner. The final result is ΔY = 100 + 100 × 4/5 + 100 × [4/5]² + 100 × [4/5]³ or,
ΔY = 100 + 100 × 0.8 + 100 × (0.8)² + 100 × (0.8)³
= 100 + 80+ 64 + 51.2… = 500
that is 100 × 1/1 – 4/5
100 × 1/1/5
100 × 5 = Rs 500 crores
For instance if C = 100 + 0.8Y, I = 100,
Then Y = 100+ 0.8Y + 100
0. 2Y = 200
Y = 200/0.2 = 1000 → Point B
If I is increased to 110, then
0. 2Y = 210
Y = 210/0.2 = 1050 → Point D
For Rs 10 increase in I, Y has increased by Rs 50.
This is due to multiplier effect.
At point A, Y = C = 500
C = 100 + 0.8 (500) = 500; S = 0
At point B, Y = 1000
C = 100 + 0.8 (1000) = 900; S = 100 = I
At point D, Y = 1050
C = 100 + 0.8 (1050) = 940; S = 110 = I
When I is increased by 10, Y increases by 50.
This is multiplier effect (K = 5)
K = \(\frac{1}{0.2}\) = 5

[OR]

(b) Explain about Marginal Efficiency of Capital [MEC] short run factors and long run factors.
Answer:
(a) Short – Run Factors
(i) Demand for the product:

• If the market for a particular good is expected to grow and its costs are likely to fall, the rate of return from investment will be high.
• If entrepreneurs expect a fall in demand for goods and a rise in cost, the investment will decline.

(ii) Liquid assets:

• If the entrepreneurs are holding large volume of working capital, they can take advantage of the investment opportunities that come in their way.
  The MEC will be high.

(iii) Sudden changes in income:

• The MEC is also influenced by sudden changes in income of the entrepreneurs.
• If the business community gets windfall profits, or tax concession the MEC will be high and hence investment in the country will go up.
• On the other hand, MEC falls with the decrease in income.

(iv) Current rate of investment:

• Another factor which influences MEC is the current rate of investment in a particular industry.
• If in a particular industry, much investment has already taken place and the rate of investment currently going on in that industry is also very large, then the marginal efficiency of capital will be low.

(v) Waves of optimism and pessimism:

1. The marginal efficiency of capital is also affected by waves of optimism and pessimism in the business cycle.
2. If businessmen are optimistic about future, the MEC will be likely to be high.
3. During periods of pessimism the MEC is under estimated and so will be low.

(b) Long – Run Factors
The long run factors which influence the marginal efficiency of capital are as follows:
(i) Rate of growth of population:

• Marginal efficiency of capital is also influenced by the rate of growth of population.
• If population is growing at a rapid speed, it is usually believed that the demand of various types of goods will increase.
• So a rapid rise in the growth of population will increase the marginal efficiency of capital and a slowing down in its rate of growth will discourage investment and thus reduce marginal efficiency of capital.

(ii) Technological progress:

• If investment and technological development take place in the industry, the prospects of increase in the net yield brightens up.
• For example, the development of automobiles in the 20th century has greatly stimulated the rubber industry, the steel and oil industry etc.
• So we can say that inventions and technological improvements encourage investment in various projects and increase marginal efficiency of capital.

(iii) Monetary and Fiscal policies:
Cheap money policy and liberal tax policy pave the way for greater profit margin and so MEC is likely to be high.

(iv) Political environment:
Political stability, smooth administration, maintenance of law and order help to improve MEC.

(v) Resource availability:
Cheap and abundant supply of natural resources, efficient labour and stock of capital enhance the MEC.

Question 43 (a).
Briefly explain the Monetary Economics and money.
Answer:
Monetary Economics is a branch of economics that provides a framework for analyzing money and its functions as a medium of exchange, store of value and unit of account. It examines the effects of monetary systems including regulation of money and associated financial institutions.

Meaning

1. Money is anything that is generally accepted as payment for goods and services and repayment of debts and that serves as a medium of exchange.
2. A medium of exchange is anything that is widely accepted as a means of payments.
3. In recent years, the importance of credit has increased in all the countries of the world.
4. Credit instruments are used on an extensive scale.
5. The use of cheques, bills of exchange, etc., has gone up.
6. It should however, be remembered that money is the basis of credit.

[OR]

(b) What are the objectives of Monetary Policy? Explain.
Answer:
The specific objectives of monetary policy are Objectives of monetary policy:

1. Neutrality of Money
2. Stability of Exchange Rates
3. Price Stability
4. Full Employment
5. Economic Growth
6. Equilibrium in the Balance of Payments

1. Neutrality of Money:

• Economists like Wicksteed, Hayek and Robertson are the chief exponents of neutral money.
• They hold the view that monetary authority should aim at neutrality of money in the economy.
• Monetary changes could be the root cause of all economic fluctuations.
• According to neutralists, the monetary change causes distortion and disturbances in the proper operation of the economic system of the country.

2. Exchange Rate Stability:

• Exchange rate stability was the traditional objective of monetary authority.
• This was the main objective under Gold Standard among different countries.
• When there was disequilibrium in the balance of payments of the country, it was automatically corrected by movements.

3. Price Stability:

• Economists like Crustave Cassel and Keynes suggested price stabilization as a main objective of monetary policy.
• Price stability is considered the most genuine, objective of monetary policy.
• Stable prices repose public confidence,
• It promotes business activity and ensures equitable distribution of income and wealth.

4. Full Employment:

• During world depression, the problem of unemployment had increased rapidly.
• It was regarded as socially dangerous, economically wasteful and morally deplorable.
• Thus, full employment was considered as the main goal of monetary policy.

5. Economic Growth:

• Economic growth is the process whereby the real per capita income of a country increases over a long period of time.
• It implies an increase in the total physical or real output, production of goods for the satisfaction of human wants.
• Monetary policy should promote sustained and continuous economic growth by maintaining equilibrium between the total demand for money and total production capacity and further creating favourable conditions for saving and investment.

6. Equilibrium in the Balance of Payments:
Equilibrium in the balance of payments is another objective of monetary policy which emerged significant in the post war years.

Question 44 (a).
What do you mean by balance of payments?
Answer:
Balance of Payments (BOP):
1. BoP is a systematic record of a country’s economic and financial transactions with the rest of the world over a period of time.

2. When a payment is received from a foreign country, it is a credit transaction while a payment to a foreign country is a debit transaction.

3. The principal items shown on the credit side are exports of goods and services, transfer receipts in the form of gift etc., from foreigners, borrowing from abroad, foreign direct investment and official sale of reserve assets including gold to foreign countries and international agencies.

4. The principal items on the debit side include imports of goods and services, transfer payments to foreigners, lending to foreign countries, investments by residents in foreign countries and official purchase of reserve assets or gold from foreign countries and international agencies.

4. Foreign production by FDI is useful to substitute foreign trade. .
5. FDI is also influenced by the income generated from the trade and regional integration schemes.
6. FDI is helpful to accelerate the economic growth by facilitating essential imports needed for carrying out development programmes like capital goods, technical know-how, raw materials and other inputs and even scarce consumer goods.
7. FDI may be required to fill the trade gap.
8. FDI is encouraged by the factors such as foreign exchange shortage, desire to create employment and acceleration of the pace of economic development.
9. Many developing countries strongly prefer foreign investment to imports.
10. However, the real impact of FDI on different sections of an economy.

Question 45 (a).
Describe the Types of Terms of Trades.
Answer:
Types of Terms of Trade:
The different concepts of terms of trade were classified by Gerald M.Meier into the following three categories:
Terms of Trade related to the Ratio of Exchange between Commodities:

1. Net Barter Terms of Trade:
This type was developed by Taussig in 1927. The ratio between the prices of exports and of imports is called the “net barter terms of trade’. It is named by Viner as the ‘commodity terms of trade’.
It is expressed as:
T_n = (P_x / P_m) × 100
Where,
T_n = Net Barter Terms of Trade
P_x = Index number of export prices
P_m = Index number of import prices
This is used to measure the gain from international trade. If ‘T_n’ is greater than 100, then it is a favourable terms of trade which will mean that for a rupee of export, more of imports can be received by a country.

2. Gross Barter Terms of Trade:
This was developed by Taussig in 1927 as an improvement over the net terms of trade. It is an index of relationship between total physical quantity of imports and the total physical quantity of exports.
T_g = (Q_m / Q_x) × 100
Where,
Q_m = Index of import quantities
Q_x = Index of export quantities
If for a given quantity of export, more quantity of import can be consumed by a country, then one can say that terms of trade are favourable.

3. Income Terms of Trade:
The income terms of trade was given by G.S.Dorrance in 1948. It is the index of the value of exports divided by the price index for imports multiplied by quantity index of experts. In other words, it is the net barter terms of trade of a country multiplied by its exports- volume index.
T_y = (P_x / P_m ) Q_x
Where,
P_x = Price index of exports
P_m = Price index of imports
Q_x = Quantity index of exports

(b) Explain the principles of federal finance.
Answer:
Principles of Federal Finance:
In the case of federal system of finance, the following main principles must be applied:

1. Principle of Independence.
2. Principle of Equity.
3. Principle of Uniformity.
4. Principle of Adequacy.
5. Principle of Fiscal Access.
6. Principle of Integration and coordination.
7. Principle of Efficiency.
8. Principle of Administrative Economy.
9. Principle of Accountability.

1. Principle of Independence:

• Under the system of federal finance, a Government should be autonomous and free about the internal financial matters concerned.
• It means each Government should have separate sources of revenue, authority to levy taxes, to borrow money and to meet the expenditure.
• The Government should normally enjoy autonomy in fiscal matters.

2. Principle of Equity:
From the point of view of equity, the resources should be distributed among the different states so that each state receives a fair share of revenue.

3. Principle of Uniformity:
In a federal system, each state should contribute equal tax payments for federal finance.

4. Principle of Adequacy of Resources:

• The principle of adequacy means that the resources of each Government i.e. Central and State should be adequate to carry out its functions effectively.
• Here adequacy must be decided with reference to both current as well as future needs.
• Besides, the resources should be elastic in order to meet the growing needs and unforeseen expenditure like war, floods etc.

5. Principle of Fiscal Access:

• In a federal system, there should be possibility for the Central and State Governments to develop new source of revenue within their prescribed fields to meet the growing financial needs.
• In nutshell, the resources should grow with the increase in the responsibilities of the Government.

6. Principle of Integration and coordination:

• The financial system as a whole should be well integrated.
• There should be perfect coordination among different layers of the financial system of the country.
• Then only the federal system will survive.
• This should be done in such a way to promote the overall economic development of the country.

7. Principle of Efficiency:

• The financial system should be well organized and efficiently administered.
• Double taxation should be avoided.

8. Principle of Administrative Economy:

• Economy is the important criterion of any federal financial system.
• That is, the cost of collection should be at the minimum level and the major portion of revenue should be made available for the other expenditure outlays of the Governments.

9. Principle of Accountability:
Each Government should be accountable to its own legislature for its financial decisions i.e. the Central to the Parliament and the State to the Assembly.

Question 47 (a).
What are the similarities of Public and Private Finance?
Answer:
(i) Rationality:

• Both public finance and private finance are based on rationality.
• Maximization of welfare and least cost factor combination underlie both.

(ii) Limit to borrowing:

• Both have to apply restraint with regard to borrowing.
• The Government also cannot live beyond its means.
• There is a limit to deficit financing by the state also.

(iii) Resource utilisation:

• Both the private and public sectors have limited resources at their disposal.
• So both attempt to make optimum use of resources.

(iv) Administration:

• The effectiveness of measures of the Government as well as private depends on the administrative machinery.
• If the administrative machinery is inefficient and corrupt it will result in wastages and losses.

Question 21.
Define Mixed Economy (or) Mixedism.
Answer:
In a mixed economy system both private and public sectors co-exist and work together towards economic development. It is a combination of both capitalism and socialism. It tends to eliminate the evils of both capitalism and socialism. In these economies, resources are owned by individuals and the government. India, England, France and Brazil are the examples of mixed economy.

Question 22.
Write the Factor Incomes group.
Answer:
Factor incomes are grouped under labour income, capital income and mixed income.

1. Labour income – Wages and salaries, fringe benefits, employer’s contribution to social security.
2. Capital income – Profit, interest, dividend and royalty
3. Mixed income – Farming, sole proprietorship and other professions.

Question 23.
Give reasons for labour retrenchment at present situation.
Answer:

1. Modem technology being capital intensive requires less labourers and contributes to technological unemployment.
2. Now a days, invention and innovations lead to the adoption of new techniques there by the existing workers are retrenched.
3. Labour saving devices are responsible for technological unemployment.

Question 24.
Write two approaches of the equilibrium level of Income in Keynesian theory?
Answer:
There are two approaches to determination of the equilibrium level of income in Keynesian theory. These are:

1. Aggregate demand – Aggregate supply approach
2. Saving – Investment approach

Question 25.
Define average propensity to consume (APC).
Answer:
Average Propensity to Consume:
The average propensity to consume is the ratio of consumption expenditure to any particular level of income.” Algebraically it may be expressed as under:
APC = \(\frac{C}{Y}\)
Where, C = Consumption; Y = Income

Question 26.
Define inflation.
Answer:

1. Inflation is a consistent and appreciable rise in the general price level.
2. In other words, inflation is the rate at which the general level of prices for goods and services is rising and consequently the purchasing power of currency is falling.
3. “Too much of Money chasing too few goods” – Coulbourn

PART – III

Answer any seven question in which Question No. 40 is compulsory. [7 x 3 = 21]

Question 31.
Outline the major merits of capitalism.
Answer:
Merits of Capitalism

1. Automatic Working: Without any government intervention, the economy works automatically.
2. Efficient Use of Resources: All resources are put into optimum use.
3. Incentives for Hard work: Hard work is encouraged and entrepreneurs get more profit for more efficiency.
4. Economic Progress: Production and productivity levels are very high in capitalistic economies.
5. Consumers Sovereignty: All production activities are aimed at satisfying the consumers.
6. Higher Rates of Capital Formation: Increase in saving and investment leads to higher rates of capital formation.
7. Development of New Technology: As profit is aimed at, producers invest on new technology and produce quality goods.

Question 32.
Write briefly about national income and welfare.
Answer:
National Income is considered as an indicator of the economic wellbeing of a country.
The per capita income as an index of economic welfare suffers from limitations which are stated below:

1. The economic welfare depends upon the composition of goods and services provided. The greater the proportion of capital goods over consumer goods, the improvement in economic welfare will be lesser.
2. Higher GDP with greater environmental hazards such as air, water and soil pollution will be little economic welfare.
3. The production of war goods will show the increase in national output but not welfare.
4. An increase in per capita income may be due to employment of women and children or forcing workers to work for long hours. But it will not promote economic welfare.

Question 33.
Give short note on Expenditure method.
Answer:
List out the assumptions of Say’s law.
The Say’s Law of market is based on the following assumptions:

1. No single buyer or seller of commodity or an input can affect price.
2. Full employment.
3. People are motivated by self interest and self – interest determines economic decisions.
4. The laissez faire policy is essential for an automatic and self adjusting process of full employment equilibrium. Market forces determine everything right.
5. There will be a perfect competition in labour and product market.
6. There is wage-price flexibility.
7. Money acts only as a medium of exchange.
8. Long – run analysis.
9. There is no possibility for over production or unemployment.

Question 34.
Explain any three subjective and objective factors influencing the consumption function.
Answer:
Subjective Factors:

1. The motive of precaution: To build up a reserve against unforeseen contingencies. e.g. Accidents, sickness.
2. The motive of foresight: The desire to provide for anticipated future needs. e.g. Old age.
3. The motive of calculation: The desire to enjoy interest and appreciation.

Objective Factors:

1. Income Distribution: If there is large disparity between rich and poor, the consumption is low because the rich people have low propensity to consume and high propensity to save.
2. Price level: Price level plays an important role in determining the consumption function. When the price falls, real income goes up; people will consume more and propensity to save of the society increases.
3. Wage level: Wage level plays an important role in determining the consumption function and there is positive relationship between wage and consumption. Consumption expenditure increases with the rise in wages. Similar is the effect with regard to windfall gains.

Question 35.
Explain the Evolution Of money.
Answer:

1. The introduction of money as a medium of exchange was one of the greatest inventions of mankind.
2. Before money was invented, exchange took place by Barter, that is, commodities and services were directly exchanged for other commodities and services.
3. Under the barter system, buyers and sellers of commodities had to face a number of difficulties.
4. Surplus goods were exchanged for money which in turn was exchanged for other needed goods.
5. Goods like furs, skins, salt, rice, wheat, utensils, weapons, etc. were commonly used as money.
6. Such exchange of goods for goods was known as “Barter Exchange” or “Barter System”.

Question 36.

3. Any other matter referred to the Commission by the President of India in the interest of sound finance. Several issues like debt relief, financing of calamity relief of states, additional excise duties, etc. have been referred to the Commission invoking this clause.

Question 39.
Explain the limitations of statistics.
Answer:
1. Statistics is not suitable to the study of qualitative phenomenon: Since statistics is basically a science and deals with a set of numerical data. It is applicable to the study of quantitative measurements. As a matter of fact, qualitative aspects like empowerment, leadership, honesty, poverty, intelligence etc., cannot be expressed numerically and statistical analysis cannot be directly applied on these qualitative phenomena.

2. Statistical laws are not exact: It is well known that mathematical and physical sciences are exact. But statistical laws are not exact and statistical laws are only approximations. Statistical conclusions are not universally true. They are true only on an average.

3. Statistics table may be misused: Statistics must be used only by experts; otherwise, statistical methods are the most dangerous tools on the hands of the inexpert. The use of statistical tools by the inexperienced and untrained persons might lead to wrong conclusions.

4. Statistics is only one of the methods of studying a problem: Statistical method does not provide complete solution of the problems because problems are to be studied taking the background of the countries culture, philosophy, religion etc., into consideration. Thus the statistical study should be supplemented by other evidences.

Question 40.
Briefly explain the kinds of measures of dispersion.
Answer:
There are two kinds of measures of dispersion, namely

1. Absolute measure of dispersion
2. Relative measure of dispersion

1. Absolute measure of dispersion indicates the amount of variation in a set of values in terms of units of observations.

2. Relative measures of dispersion are free from the units of measurements of the observations. They are pure numbers. They are used to compare the variation in two or more sets, which are having different units of measurements of observations.

3. Standard Deviation is one of the methods of Absolute measure of dispersion. Karl Pearson introduced the concept of standard deviation in 1893. Standard deviation is also called Root- Mean Square Deviation. The reason is that it is the square-root of the mean of the squared deviation from the arithmetic mean. It provides accurate result. Square of standard deviation is called Variance.

(b) Narrate the equilibrium between ADF and ASF with diagram.
Answer:
Equilibrium between ADF and ASF

• Under the Keynes theory of employment, a simple two sector economy consisting of the household sector and the business sector is taken to understand the equilibrium between ADF and ASF.
• All the decisions concerning consumption expenditure are taken by the individual households, while the business firms take decisions concerning investment.
• It is also assumed that consumption function is linear and planned investment is autonomous.
• There are two approaches to y determination of the equilibrium level of income in Keynesian theory. These are :1. Aggregate demand – Aggregate supply approach, 2. Saving – Investment approach
• In this chapter, out of these two, aggregate Tg demand and aggregate supply approach is alone explained to understand the determination of equilibrium level of income and employment.
• The concept of effective demand is more Q clearly shown in the figure.
• In the figure, the aggregate demand and aggregate supply reach equilibrium at point E. The employment level is N₀ at that point.
• At ON₁ employment, the aggregate supply is N₁ R₁. But they are able to produce M₁ N₁. The expected level of profit is M₁R₁.
• To attain this level of profit, entrepreneurs will employ more labourers.
• The tendency to employ more labour will stop once they reach point E.
• At all levels of employment beyond, ON₀, the aggregate demand curve is below the aggregate supply curve indicating loss to the producers.
• Hence they will never employ more than ON₀ labour.
• Thus effective demand concept becomes a crucial point in determining the equilibrium level of output in the capitalist economy or a free market economy in the Keynesian system.
• It is important to note that the equilibrium level of employment need not be the full employment level (N₁) from the Figure, it is understood that the difference between N₀ – N₁ is the level of unemployment.
• Thus the concept of effective demand becomes significant in explaining the under employment equilibrium.

Question 42 (a).
Explain Keynes psychological law of consumption function with diagram.
Answer:
The three propositions of the law

Proposition (1):
Income increases by Rs 60 crores and the increase in consumption is by Rs 50 crores.
Proposition (2):
The increased income of Rs 60 crores in each case is divided in some proportion between consumption and saving respectively, (i.e., Rs 50 crores and Rs 10 crores).
Proposition (3):
As income increases consumption as well as saving increase. Neither consumption nor saving has fallen.

Diagrammatically, the three propositions are explained in figure. Here, income is measured horizontally and consumption and saving are measured on the vertical axis. C is the consumption function curve and 45° line represents income consumption equality.

Proposition (1):
When income increases from 120 to 180 consumption also increases from 120 to 170 but the increase in consumption is less than the increase in income, 10 is saved.

Proposition (2):
When income increases to 180 and 240, it is divided in some proportion between consumption by 170 and 220 and saving by 10 and 20 respectively.

Proposition (3):
Increases in income to 180 and 240 lead to increased consumption 170 and 220 and increased saving 20 and 10 than before. It is clear from the widening area below the C curve and the saving gap between 45° line and C curve.

[OR]

(b) Explain the functions of money.
Answer:

1. Primary Functions:
(i) Money as a medium of exchange: This is considered as the basic function of money. Money has the quality of general acceptability, and all exchanges take place in terms of money.

(ii) Money as a measure of value: The second important function of money is that it measures the value of goods and services. In other words, the prices of all goods and services are expressed in terms of money. Money is thus looked upon as a collective measure of value.

2. Secondary Functions:
(i) Money as a Store of value: Savings done in terms of commodities were not permanent. But, with the invention of money, this difficulty has now disappeared and savings are now done in terms of money. Money also serves as an excellent store of wealth, as it can be easily converted into other marketable assets, such as, land, machinery, plant etc.

(ii) Money as a Standard of Deferred Payments: Borrowing and lending were difficult problems under the barter system. In the absence of money, the borrowed amount could be returned only in terms of goods and services. But the modem money-economy has greatly facilitated the borrowing and lending processes.

(iii) Money as a Means of Transferring Purchasing Power: The field of exchange also went on extending with growing economic development. The exchange of goods is now extended to distant lands.

3. Contingent Functions:
(i) Basis of the Credit System: Money is the basis of the Credit System. Business transactions are either in cash or on credit.

(ii) Money facilitates distribution of National Income: The task of distribution of national income was exceedingly complex under the barter system.

(iii) Money helps to Equalize Marginal Utilities and Marginal Productivities: Consumer can obtain maximum utility only if he incurs expenditure on various commodities in such a manner as to equalize marginal utilities accruing from them. Now in equalizing these marginal utilities, money plays an important role, because the prices of all commodities are expressed in money.

(iv) Money Increases Productivity of Capital: Money is the most liquid form of capital. In other words, capital in the form of money can be put to any use.

4. Other Functions:
(i) Money helps to maintain Repayment Capacity: Money possesses the quality of general acceptability. To maintain its repayment capacity, every firm has to keep assets in the form of liquid cash. The firm ensures its repayment capacity with money.

(ii) Money represents Generalized Purchasing Power: Purchasing power kept in terms of money can be put to any use. It is not necessary that money should be used only for the purpose for which it has been served.
(iii) Money gives liquidity to Capital: Money is the most liquid form of capital. It can be put to any use.

Question 43 (a).
Elucidate the functions of Commercial Banks.

II. Secondary Functions:
The secondary functions can be classified under three heads, namely, agency functions, general utility functions, and other functions.
1. Agency Functions: It implies that commercial banks act as agents of customers by performing various functions.

• Collecting Cheques: Banks collect cheques and bills of exchange on the behalf of
  their customers through clearing house facilities provided by the central bank.
• Collecting Income: Commercial banks collect dividends, pension, salaries, rents, and interests on investments on behalf of their customers. A credit voucher is sent to customers for information when any income is collected by the bank.
• Paying Expenses: Commercial banks make the payments of various obligations of customers, such as telephone bills, insurance premium, school fees, and rents.

2. General Utility Functions: It implies that commercial banks provide some utility services to customers by performing various functions.

• Providing Locker Facilities: Commercial banks provide locker facilities to its customers for safe custody of jewellery, shares, debentures, and other valuable items. This minimizes the risk of loss due to theft at homes. Banks are not responsible for the items in the lockers.
• Issuing Traveler’s Cheques: Banks issue traveler’s cheques to individuals for traveling outside the country. Traveler’s cheques are the safe and easy way to protect money while traveling.
• Dealing in Foreign Exchange: Commercial banks help in providing foreign exchange to businessmen dealing in exports and imports. However, commercial banks need to – take the permission of the Central Bank for dealing in foreign exchange.

3. Transferring Funds: It refers to transferring of funds from one bank to another. Funds are transferred by means of draft, telephonic transfer, and electronic transfer.

4. Letter of Credit: Commercial banks issue letters of credit to their customers to certify their creditworthiness.

• Underwriting Securities: Commercial banks also undertake the task of underwriting securities. As public has full faith in the credit worthiness of banks, public do not hesitate in buying the securities underwritten by banks.
• Electronic Banking: It includes services, such as debit cards, credit cards, and Internet banking.

III. Other Functions:

1. Money Supply: It refers to one of the important functions of commercial banks that help in increasing money supply.
2. Credit Creation: Credit Creation means the multiplication of loans and advances. Commercial banks receive deposits from the public and use these deposits to give loans:

[OR]

(b) Describe the Merger of Banks.
Answer:
Merger of Banks:

1. Union Cabinet decided to merge all the remaining five associate banks of State Bank Group with State Bank of India in 2017.

7. After the merger, the total customer base of SBI increased to 37 crore with a branch network of around 24,000 and around 60,000 ATMs across the country.

Question 44 (a).
Explain the Adam Smith’s Theory of Absolute Cost Advantage Theory and Assumptions with diagram.
Answer:
Adam Smith’s Theory of Absolute Cost Advantage:
Adam Smith argued that all nations can be benefitted when there is free trade and specialisation in terms of their absolute cost advantage.

The Theory:
According to Adam Smith, the basis of international trade was absolute cost advantage.

Trade between two countries would be mutually beneficial when one country produces a commodity at an absolute cost advantage over the other country which in turn produces another commodity at an absolute cost advantage over the first country.

Assumptions:

1. There are two countries and two commodities (2×2 model).
2. Labour is the only factor of production.
3. Labour units are homogeneous.
4. The cost or price of a commodity is measured by the amount of labour required to produce it.
5. There is no transport cost.

Illustration:
Absolute cost advantage theory can be illustrated with the help of the following example.

Absolute Cost Advantage:

1. From the illustration, it is clear that India has an absolute advantage in the production of wheat over China and China has an absolute advantage in the production of cloth over India.
2. Therefore, India should specialize in the production of wheat and import cloth from China.
3. China should specialize in the production of cloth and import wheat from India.
4. This kind of trade would be mutually beneficial to both India and China.

[OR]

(b) Briefly explain causes for the increase in public debt.
Answer:
Causes for the Increase in Public debt:
The causes for enormous growth of public debt may be studied under the following sub-headings:
1. War and Preparation of war
Waging war has become one of the important causes for incurring debts by the governments. In modem times, the preparation for war and nuclear defence programmes take away the major share of the government’s revenue and so it incurs debt.

2. Social obligations
Modem states are considered to be ‘Welfare States and they have to undertake many social obligations like public health, sanitation, education,insurance, transport and communications, etc., besides providing the minimum necessaries of life to the citizens of the country. To finance these, the State has to incur a heavy public debt.

3. Economic Development and Deficit
The government has to undertake many projects for economic development of the country. Construction of railways, power projects, irrigation projects, heavy industries, etc., could be thought of only by means of mobilising resources in the form of public debt. Due to heavy public expenditure, the governments always face deficit budget. Such deficits have to be financed only through borrowings.

4. Employment
Most of the governments of modem days face the problem of unemployment and it has become the duty to solve this by making huge public expenditure. To solve the unemployment problem, and to fight recession, the government has to make huge expenditures. For this the States have to resort to public debt.

5. Controlling inflation
The Government can withdraw excess money from circulation, by raising public debt and thus prevent prices from rising.

6. Fighting depression
During the depression phase, private investment is lacking. The Government applies compensatory public spending by borrowing from internal and external sources.

Question 46 (a).
What is land pollution? Mention the causes of land pollution.
Answer:
The land pollution is defined as, “the degradation of land because of the disposal of waste on the land”. Any substance (solid, liquid or gaseous) that is discharged, emitted or deposited in the environment in such a way that it alters the environment causes land pollution.
Causes of Land Pollution:
(i) Deforestation and soil erosion:

1. Deforestation carried out to create dry lands is one of the major concerns.
2. Land that is once converted into a dry or barren land, can never be made fertile again, whatever the magnitude of measures to convert it.

(ii) Agricultural activities:

1. With growing human and pet animal population, demand for food has increased considerably.
2. Farmers often use highly toxic fertilizers and pesticides to get rid off insects, fungi and bacteria from their crops.
3. However the overuse of these chemicals, results in contamination and poisoning of land.

(iii) Mining activities:
During extraction and mining activities, several land spaces are created beneath the surface.

(iv) Landfills:

1. Each household produces tones of garbage each year due to changing economic lifestyle of the people.
2. Garbage like plastic, paper, cloth, wood and hospital waste get accumulated.
3. Items that cannot be recycled become a part of the landfills that cause land pollution.

(v) Industrialization:

1. Due to increasing consumerism more industries were developed which led to deforestation.
2. Research and development paved the way for modem fertilizers and chemicals that were highly toxic and led to soil contamination.

(vi) Construction activities:

1. Due to urbanization, large amount of construction activities are taking place.
2. This has resulted in large waste articles like wood, metal, bricks, plastic.
3. These are dumped at the outskirts of urban areas that lead to land pollution.

(vii) Nuclear waste:

1. The leftover radioactive materials, harmful and toxic chemicals affect human health.
2. They are dumped beneath the earth to avoid any casualty.

[OR]

(b) What are the effects of Land pollution?
Answer:
Effects of Land Pollution:
(i) Soil pollution:

1. Soil pollution is another form of land pollution, where the upper layer of the soil is damaged.
2. This is caused by the ovemse of chemical fertilizers, and pesticides.
3. This leads to loss of fertile land.
4. Pesticides kill not only pests and also human beings.

(ii) Health Impact:

1. The land when contaminated with toxic chemicals and pesticides lead to problem of skin cancer and human respiratory system.
2. The toxic chemicals can reach our body through foods and vegetables.

(iii) Cause for Air pollution:

1. Landfills and waste dumping lead to air pollution.
2. The abnormal toxic substances spread in the atmosphere cause transmit respiratory diseases among the masses.

(iv) Effect on wildlife:

Question 34.
Describe the types of unemployment.
Answer:
The following are the types of unemployment.
Types of unemployment:

1. Cyclical Unemployment
2. Frictional Unemployment
3. Technical Unemployment
4. Disguised Unemployment
5. Seasonal Unemployment
6. Educated Unemployment
7. Structural Unemployment

1. Cyclical Unemployment:

• This unemployment exists during the downturn phase of trade cycle in the economy.
• In a business cycle during the period of recession and depression, income and output fall leading to widespread unemployment.
• It is caused by deficiency of effective demand.
• Cyclical unemployment can be cured by public investment or expansionary monetary policy.

2. Seasonal Unemployment:

• This type of unemployment occurs during certain seasons of the year.
• In agriculture and agro based industries like sugar, production activities are carried out only in some seasons.
• These industries offer employment only during that season in a year. Therefore people may remain unemployed during the off season.
• Seasonal unemployment happens from demand side also; for example ice cream industry, holiday resorts etc.

3. Frictional Unemployment (Temporary Unemployment):

• Frictional unemployment arises due to imbalance between supply of labour and demand for labour.
• This is because of immobility of labour, lack of necessary skills, break down of machinery.
• shortage of raw materials etc.
• The persons who lose jobs and in search of jobs are also included under frictional unemployment.

4. Educated Unemployment:

• Sometimes educated people are underemployed or unemployed when qualification does
  not match the job.
• Faulty education system, lack of employable skills, mass student turnout and preference for white collar jobs are highly responsible for educated unemployment in India.

5. Technical Unemployment:

• Modem technology being capital intensive requires less labourers and contributes to technological unemployment.
• Now a days, invention and innovations lead to the adoption of new techniques there by the existing workers are retrenched.
• Labour saving devices are responsible for technological unemployment.

6. Structural Unemployment:

• Structural unemployment is due to drastic change in the structure of the society.
• Lack of demand for the product or shift in demand to other products cause this type of unemployment.
• For example rise in demand for mobile phones has adversely affected the demand for cameras, tape recorders etc.
• So this kind of unemployment results from massive and deep rooted changes in economic structure.

7. Disguised Unemployment:

• Disguised unemployment occurs when more people are than what is actually required.
• Even if some workers are withdrawn, production does not suffer.
• This type of unemployment is found in agriculture.
• A person is said to be disguisedly by unemployed if his contribution to output is less than what he can produce by working for normal hours per day.
• In this situation, marginal productivity of labour is zero or less or negative.

Answer:

[OR]

(b) What are the difficulties involved in the measurement of national income?
Answer:
Difficulties in Measuring National Income:
In India, a special conceptual problem is posed by the existence of a large, unorganised and non-monetised subsistence sector where the barter system still prevails for transacting goods and services. Here, a proper valuation of output is very difficult.

Transfer payments:

1. Government makes payments in the form of pensions, unemployment allowance, subsidies, etc. These are government expenditure.
2. But they are not included in the national income.
3. Because they are paid without adding anything to the production processes.
4. During a year, Interest on national debt is also considered transfer payments because it is paid by the government to individuals and firms on their past savings without any productive work.

Difficulties in assessing depreciation allowance:

1. The deduction of depreciation allowances, accidental damages, repair and replacement charges from the national income is not an easy task.
2. It requires high degree of judgment to assess the depreciation allowance and other charges.

Unpaid services:

1. A housewife renders a number of useful services like preparation of meals, serving, tailoring, mending, washing, cleaning, bringing up children, etc.
2. She is not paid for them and her services are not directly included in national income.

Income from illegal activities:

1. Income earned through illegal activities like gambling, smuggling, illicit extraction of . liquor, etc., is not included in national income.
2. Such activities have value and satisfy the wants of the people but they are not considered as productive from the point of view of society.

Production for self-consumption and changing price:

1. Farmers keep a large portion of food and other goods produced on the farm for self consumption.
2. The problem is whether that part of the produce which is not sold in the market can be included in national income or not.

Capital Gains:

1. The problem also arises with regard to capital gains.
2. Capital gains arise when a capital asset such as a house, other property, stocks or shares, etc. is sold at higher price than was paid for it at the time of purchase.
3. Capital gains are excluded from national income.

Statistical problems:

1. There are statistical problems, too. Great care is required to avoid double counting. Statistical data may not be perfectly reliable, when they are compiled from numerous sources.
2. Skill and efficiency of the statistical staff and cooperation of people at large are also equally important in estimating national income.

Question 42 (a).
Write short note on the implications of Say’s law.
Answer:
Implications of Say’s Law:

1. There is no possibility for over production or unemployment.
2. If there exist unutilized resources in the economy, it is profitable to employ them up to the point of full employment. This is true under the condition that factors are willing to accept rewards on a par with their productivity.
3. As automatic price mechanism operates in the economy, there is no need for government intervention. (However, J.M. Keynes emphasized the role of the State)
4. Interest flexibility brings about equality between saving and investment.
5. Money performs only the medium of exchange function in the economy, as people will not hold idle money.

[OR]

(b) State the propositions of Keynes’s Psychological Law of Consumption.
Answer:
Propositions of the Law:
This law has three propositions:
(i) When income increases, consumption expenditure also increases but by a smaller amount. The reason is that as income increases, we wants are satisfied side by side, so that the need to spend more on consumer goods diminishes. So, the consumption expenditure increases with increase in income but less than proportionately.

(ii) The increased income will be divided in some proportion between consumption expenditure and saving. This follows from the first proposition because when the whole of increased income is not spent on consumption, the remaining is saved. In this way, consumption and saving move together.

(iii) Increase in income always leads to an increase in both consumption and saving. This means that increased income is unlikely to lead to fall in either consumption or saving. Thus with increased income both consumption and saving increase.

Question 43 (a).
Bring out the methods of credit control.
Answer:
Methods of Credit Control:
1. Bank Rate Policy:
The bank rate is the rate at which the Central Bank of a country’ is prepared to re-discount the first class securities.

2. Open Market Operations:

• In narrow sense, the Central Bank starts the purchase and sale of Government securities in the money market.
• In Broad Sense, the Central Bank purchases and sells not only Government securities but also other proper eligible securities like bills and securities of private concerns.

3. Variable Reserve Ratio:
(i) Cash Reserves Ratio:

• Under this system the Central Bank controls credit by changing the Cash Reserves Ratio.
• For example, if the Commercial Banks have excessive cash reserves on the basis of which they are creating too much of credit,this will be harmful for the larger interest of the economy.
• So it will raise the cash reserve ratio which the Commercial Banks are required to maintain with the Central Bank.

(ii) Statutory Liquidity Ratio:

• Statutory Liquidity Ratio (SLR) is the amount which a bank has to maintain securities.
• The quantum is specified as some percentage of the total demand and time liabilities (i.e., the liabilities of the bank which are payable on demand anytime, and those liabilities which are accruing in one month’s time due to maturity) of a bank.

[OR]

(b) Briefly explain the gains from International Trade Categories.
Answer:
Gains from International Trade:

• International trade helps a country to export its surplus goods to other countries and secure a better market for it.
• Similarly, international trade helps a country to import the goods which cannot be produced at all or can be produced at a higher cost.
• The gains from international trade may be categorized under four heads.

I. Efficient Production:
International trade enables each participatory country to specialize in the production of goods in which it has absolute or comparative advantages. International specialization offers the following gains.

1. Better utilization of resources.
2. Concentration in the production of goods in which it has a comparative advantage.
3. Saving in time.
4. Perfection of skills in production.
5. Improvement in the techniques of production.
6. Increased production.
7. Higher standard of living in the trading countries.

II. Equalization of Prices between Countries:
International trade may help to equalize prices in all the trading countries.

1. Prices of goods are equalized between the countries (However, in reality it has not happened).
2. The difference is only with regard to the cost of transportation.
3. Prices of factors of production are also equalized (However, in reality it has not happened).

III. Equitable Distribution of Scarce Materials:
International trade may help the trading countries to have equitable distribution of scarce resources.

IV. General Advantages of International Trade:

1. Availability of variety of goods for consumption.
2. Generation of more employment opportunities.
3. Industrialization of backward nations.
4. Improvement in relationship among countries (However, in reality it has not happened).
5. Division of labour and specialisation.
6. Expansion in transport facilities.

[OR]

(b) Briefly explain facilities offered by IMF.
Answer:
Facilities offered by IMF:
The Fund has created several new credit facilities for its members. Chief among them are:
(i) Basic Credit Facility:

• The IMF provides financial assistance to its member nations to overcome their temporary difficulties relating to balance of payments.
• A member nation can purchase from the Fund other currencies or SDRs, in exchange for its own currency, to finance payment deficits.
• The loan is repaid when the member repurchases its own currency with other currencies or SDRs.
• A member can unconditionally borrow from the Fund in a year equal to 25% of its quota.
• This unconditional borrowing right is called the reserve tranche.

(ii) Extended Fund Facility:

• Under this arrangement, the IMF provides additional borrowing facility up to 140% of the member’s quota, over and above the basic credit facility.
• The extended facility is limited for a period up to 3 years and the rate of interest is low.

(iii) Compensatory Financing Facility:

• In 1963, IMF established compensatory financing facility to provide additional financial assistance to the member countries, particularly primary producing countries facing shortfall in export earnings.
• In 1981, the coverage of the compensatory financing facility was extended to payment problem caused by the fluctuations in the cost of cereal inputs.

(iv) Buffer Stock Facility:

• The buffer stock financing facility was started in 1969.
• The purpose of this scheme was to help the primary goods (food grains) producing countries to finance contributions to buffer stock arrangements for the stabilisation of primary product prices.

(v) Supplementary Financing Facility:
Under the supplementary financing facility, the IMF makes temporary arrangements to provide supplementary financial assistance to member countries facing payments problems relating to their present quota sizes.

(vi) Structural Adjustment Facility:

• The IMF established Structural Adjustment Facility (SAF) in March 1986 to provide additional balance of payments assistance on concessional terms to the poorer member countries.
• In December 1987, the Enhanced Structural Adjustment Facility (ESAF) was set up to augment the availability of concessional resources to low income countries.
• The purpose of SAF and ESAF is to force the poor countries to undertake strong macroeconomic and structural programmes to improve their balance of payments positions and promote economic growth.

Concentration of economic power is another evil to be corrected by the Government. So, the state intervenes through control of monopolies and restrictive trade practices to curb concentration of economic power.

[OR]

(b) What are the causes of water pollution?
Answer:
Water pollution is caused due to several reasons. Here are the few major causes of water pollution:
(i) Discharge of sewage and waste water:

1. Sewage, garbage and liquid waste of households, agricultural runoff and effluents from factories are discharged into lakes and rivers.
2. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.

(ii) Dumping of solid wastes:
The dumping of solid wastes and litters in water bodies cause huge problems.

(iii) Discharge of industrial wastes:
Industrial waste contains pollutants like asbestos, lead, mercury, grease oil and petrochemicals, which are extremely harmful to both people and environment.

(iv) Oil Spill:
Sea water gets polluted due to oil spilled from ships and tankers while travelling. The spilled oil does not dissolve in water and forms a thick sludge polluting the water.

(v) Acid rain:

1. Acid rain is pollution of water caused by air pollution.
2. When the acidic particles caused by air pollution in the atmosphere mix with water vapor, it results in acid rain.

(vi) Global warming:

(i) Debt-equity ratio
(ii) Proprietary ratio
(iii) Capital gearing ratio
Balance Sheet of James Ltd. as on 31.03.2019

Answer:

Long term debts = Debentures = 3,00,000
Shareholder’s funds = Equity share capital + Preference share capital + Reserves and surplus
= 2,50,000 + 2,00,000 + 1,50,000
= 6,00,000

Funds bearing fixed interest or dividend = Preference share capital + Debentures + Long term borrowings.
= 2,00,000 + 3,00,000
= 5,00,000
Equity shareholder’s funds = Equity share capital + Reserves and surplus
= 2,50,000 + 1,50,000
= 4,00,000
Capital gearing ratio = 4 00 000 = \(\frac{500000}{400000}\) = 1.25 : 1
