Example Solution:

Question: A salesman sold two pipes at Rs. 12 each. His profit on one was 20%

and the loss on the other was 20%. Then, on the whole, he

(a) Lost Re. 1

(b) Gained Re. 1

(c) Neither gained nor lost

(d) Lost Rs. 2

Solution :

Let the cost price of the pipe on which he made profit = x.

→ x + 20x/100 = 12

→ 120x/100 = 12

→ x = 12100/120

→ x = 10

Let the cost price of the pipe on which he lost = y.

→ y – 20y/100 = 12

→ 80y/100 = 12

→ y = 12100/80

→ y = 15

Therefore, total cost price = 10 + 15 = 25

Total selling price = 2*12 = 24

So, he lost (25 – 24) = Re. 1

Option (a) is correct.
