# His gain percent is:

A fruit seller buys oranges at the rate of Rs.100 per dozen and sells at the rate of Rs.12 per dozen. His gain percent is:

- 8 1/3%
- 15%
- 12%
- 20%

**Answer: (4) 20%**

**Explanation:-**

The cost price of one dozen orange = Rs. 10

The selling price of one dozen orange = Rs.12

Then, the profit = 12 – 10

= Rs. 2

The percentage of profit = 2 x 100/10

= 20%

Then, his gain percent is 20%.

Hence, the answer is (4) 20%.
