# What is gain percentage?

If by selling 110 mangoes, the cost price of 120 mangoes is realised; the gain percentage is:

- 100/9%
- 82/9%
- 120/10%
- 100/11%

**Answer: (4) 100/11%**

**Explanation:-**

Let the cost price of 110 mangoes = Rs. 110

Then, selling price of 110 mangoes = Rs. 120

Profit = 120 – 110

= 10

Then, percentage of profit = 10 x 100/110

= 100/11%

Hence, the correct answer is option (4) 100/11%.
