A vendor sells lemons at the rate of 5 for Rs.14 gaining thereby 40%. For how much did he buy a dozen lemon?

- Rs. 20
- Rs. 22
- Rs. 24
- None of these

**Answer: (3) Rs.24**

**Explanation:-**

A vendor sells lemons at the rate of 5 for Rs.14

Gain = 40 %

Then, cost price of 5 lemon = 14 x 100/140

= Rs.10

The cost price of one lemon = 10/5

= Rs.5

Therefore, the cost price of 12 lemon = 12 x 2

= Rs.24

Hence the answer is (3) Rs.24.
