a) 20% b) 80% c) 70% d) 50%
Ans: d
Solution: Suppose the CP of each article is 1
Then CP of 10 articles = 10
SP of 10 articles = 15
Profit = 5
% profit = 5/10 × 100 = 50%
2. The cost price of 36 books is equal to the selling price of 30 books. The gain per cent is?
a) 15% b) 82 2/6% c) 20% d) 16 4/6%
Ans: c

(36 – 30)/30 × 100= 20%
3. The selling price of 5 articles is the same as the cost price of 3 articles. The gain or loss percent is?
a) 40% gain b) 40% loss c) 20% loss d) 20% gain
Ans: b
Solution:
Let CP be 1
C.P. of 3 articles = 3
= SP of P of 5 articles
Loss% = (5 – 3)/5 × 100
= 2 × 20 = 40%
4. The cost price of 18 articles is equal to the selling price of 15 articles. The gain per cent is?
a) 10% b) 30% c) 20% d ) 40%
Ans: c

5. If the cost price of 15 tables be equal to the selling price of 20 tables, the loss per cent is:
a) 10% b) 25% c) 45% d) 60%
Ans: b
Solution :
Let the cost price of one table = x
Cost price of 15 tables = 15x
and cost price of 20 tables = 20x
According to the question
Selling price of 20 tables = cost price of 15 tables = 15x
Loss = 20x – 15x = 5x
Loss% 5x/20x × 100%
= 25%
6. A person sells 400 mangoes at the cost price of 320 mangoes. His percentage of loss is?
a) 20% b)25% c) 30% d) 35%

a) 14.35% b) 20% c) 21.43% d) 16 2/3%
Ans: b

Let CP of each orange be 1
Then, CP of 10 oranges = 10
SP of 10 oranges = 12
Gain % = (2/10 × 100)% = 20%
8. If the cost price of 50 oranges is equal to the selling price of 40 oranges, then the profit per cent is

Profit = (50 – 40) = 10
Profit % = 10/40 × 100 = 25%
9. If the cost price of 10 articles is equal to the selling price of 9 articles, the gain or loss per cent is
