Solution: Question 3.
Fill up the appropriate boxes in the following table. Solution:
(i) CP = Rs 100
SP = Rs 120
CP < SP
Profit = SP – CP
= Rs 120 – Rs 100
= Rs 20

(ii) CP = Rs 110
SP = Rs 120
CP < SP
Profit = SP – CP
= Rs 120 – Rs 110
= Rs 10 (iii) CP = Rs 120
Profit = Rs 20
Profit = SP – CP
Rs 20 = SP – Rs 120
Rs 20 + Rs 120 = SP
SP = Rs 140

(iv) CP = Rs 100
SP = Rs 90
CP > SP
Loss = CP – SP
= Rs 100 – Rs 90
= Rs 10

(v) CP = Rs 120
Profit = Rs 25
Profit = SP – CP
Rs 25 = SP – Rs 120
Rs 25 + Rs 120 = SP
Rs 145 = SP
SP = Rs 145 Question 4.
Fill up the appropriate boxes in the following table. Solution:
(i) CP = Rs 110
MP = Rs 130
Profit = SP – CP
= Rs 130 – Rs.110
= Rs 20
If there is no discount MP = SP
SP = Rs 130

(ii) CP = Rs 110 Profit
MP = 130
Discount = Rs 10
= SP – CP
= Rs 120 – Rs 110
= Rs 10
SP = MP – Discount
= Rs 130 – Rs 10
= Rs 120 (iii) CP = Rs 110
MP = Rs 130
Discount = Rs 30
Loss = CP – SP
= Rs 110 – Rs 100
= Rs 10
SP = Mp – Discount
= Rs 130 – Rs 30
= Rs 100

(iv) CP = Rs 110
MP = Rs 120
Loss = CP – SP
SP = CP – Loss
= Rs 110 – Rs 10
= Rs 100
Discount = MP – SP
= Rs 120 – Rs 100
= Rs 20

(v) MP = Rs 120
Discount = Rs 10
Profit = Rs 20
Loss = Rs 0
SP = MP – Discount
= Rs 120 – Rs 10
= Rs 110
Profit = Rs 20
= SP – CP
Rs 20 = Rs 110 – CP
CP = SP – Profit
= Rs 110 – Rs 20
= Rs 90 Question 5.

Question 13.
Valavan bought 24 eggs for ₹ 96. Four of them were broken and also he had a loss of ₹ 36 on selling them. What is the selling price of one egg?
Solution:
Cost of 24 eggs = Rs 96
Since 4 of the eggs were broken, the number of remaining eggs = 24 – 4 = 20
Since the loss is Rs 36
The selling price of 20 eggs
SP = CP – Loss
= Rs 96 – Rs 36
= Rs 60
∴ Cost of 1 egg = Rs 60 / 20 = Rs. 3 Question 14.
