Question 1.
\nFill in the blanks.
\n(i) If the cost of 3 pens is Rs 18, then the cost of 5 pens is ……..
\n(ii) If Karkuzhali earns Rs 1800 in 15 days, then she earns Rs 3000 in …….. days
\nSolution:
\n(i) \u20b9 30
\nHint: \\(5 \\times \\frac{18}{3}\\) = 5 \u00d7 6 = \u20b9 30
\n(ii) 25 Days
\nHint:
\n\\(\\frac{1800}{3000}=\\frac{15}{x}\\)
\n\u21d2 x = \\(\\frac{15 \\times 3000}{1800}\\) = 25 days<\/p>\n

Question 2.
\nSay True or False.
\n(i) If the weight of 40 books is 8 kg, then the weight of 15 books is 3 kg.
\n(ii) A car travels 90 km in 3 hours with constant speed. It will travel 140 km in 5 hours at the same speed.
\nSolution:
\n(i) True
\nHint: Weight of 1 book = \\(\\frac{8}{40}=\\frac{1}{5} \\mathrm{kg}\\)
\nFlence Weight of 15 books = \\(\\frac{1}{5} \\times 15=3 \\mathrm{kg}\\)
\n(ii) False
\n1 hour the car travels = \\(\\frac{90}{3}\\) = 30 km
\nIn 5 hours the car travels = 30 \u00d7 5 = 150 km<\/p>\n

Question 3.
\nIf a person reads 20 pages of a book in 2 hours, how many pages will he read in 8 hours at the same speed?
\nSolution:
\nIn 2 hours, pages read = 20
\nIn 1 hour, pages read = \\(\\frac{20}{2}\\) = 10
\nIn 8 hours, pages read = 10 \u00d7 8
\n= 80 pages<\/p>\n

Question 4.
\nThe cost of 15 chairs is \u20b9 7500. Find the number of such chairs that can be purchased for \u20b9 12,000?
\nSolution:
\nCost of 15 chairs = Rs 7500
\nCost of 1 chair = Rs \\(\\frac{7500}{15}\\) = Rs 500
\nNumber of chairs that can be purchased for Rs 12000 = \\(\\frac{12000}{500}\\) = 24 chairs<\/p>\n

Question 5.
\nA car covers a distance of 125 km in 5 kg of LP Gas. How much distance will it cover in 3 kg of LP Gas?
\nSolution:
\nIn 5 kg of LPG gas, distance covered = 125 km
\nIn 1 kg of LPG gas, distance covered = \\(\\frac{125}{5}\\) = 25 km
\nIn 3 kg of LPG gas, distance covered = 3 \u00d7 25 km = 75 km<\/p>\n

Question 6.
\nCholan walks 6 km in 1 hour at a constant speed. Find the distance covered by him in 20 minutes at the same speed.
\nSolution:
\nIn 1 hour (60 minutes), distance covered = 6 km
\nIn 1 minute, distance covered = \\(\\frac{6 km}{60 min}\\) = \\(\\frac{6000 m}{60}\\) = 100 m
\nIn 20 minutes, distance covered = 20 \u00d7 100 m = 2000 m = 2 km<\/p>\n

Question 7.
\nThe number of correct answers given by Kaarmugilan and Kavitha in a quiz competition are in the ratio 10 : 11. If they had scored a total of 84 points in the competition, then how many points did Kavitha get?
\nSolution:
\nTotal points scored = 84 Ratio = 10 : 11
\nSum of the ratio = 10 + 11 = 21
\n21 parts = 84 points
\n1 part = \\(\\frac{84}{21}\\) = 4 points
\nKavitha = 11 parts
\nKaarmugilan = 10 parts
\nFoints scored by Kavitha = 11 parts = 11 \u00d7 4 points = 44 points<\/p>\n

\nSolution:
\nKarmegam Runs made in 9 overs = 54
\nRuns made in 1 over = \\(\\frac{54}{9}\\) = 6 runs
\nAsif Runs made in 11 overs = 77
\nRuns made in 1 over = \\(\\frac{77}{11}\\) = 7 runs
\n\u2234 Asif\u2019s run rate is better than Karmegam.<\/p>\n
