Question

if apples are bought at 11 for rs 10 & sold at 10 for rs 11, how much will be the gain %

Answer 1

To solve this question we need to get the buying price of each apple.

Buying price for 11 apples is 10,for one apple is :

10/11 = Rs 10/11

The buying price of 10 will be :

10/11 × 10 = 100/11

The selling price of 10 is 11

Profit is :

11 - 100/11 = 21/11

Percentage profit is :

21/11 × 11/100 × 100 = 21%
