# Find Out His Gain %?

By selling 100 pencils a shopkeeper gains the selling price of 20 pencils. His gain percent is

- 25%
- 20%
- 15%
- 12%

**Answer: (1) 25%**

The total number of pencils selling by s shopkeeper = 100

Gain = price of 20 pencils

Then, the profit = 20 x 100/(100 – 20)

= 20 x 100/80

= 100/4

= 25%

Then, the gain percent is 15%.

Hence, the answer is (1) 25%.
