## Question

**By selling 45 lemons for Rs 40, a man loses 20%. How many should he sell for Rs 24 to gain 20% in the transaction ?**

A. 20

B. 16

C. 22

D. 18

**Answer: D. 18**

**Solution:**

Let S.P. of 45 lemons be Rs. x.

Then, 80 : 40 = 120 : x or x = (40 × 120) / 80 = 60

For Rs.60, lemons sold = 45

For Rs.24, lemons sold = (45 / 60) ×24 = **18**.

Hence, the answer is **18.**
