A vendor bought lemons at 7 for ₹1. How many lemons must he sell for ₹1 to gain 75%?

Correct option is B

Given:

The vendor buys lemons at 7 for ₹1.

The vendor wants to gain 75% profit.

Formula Used:

S.P. = C.P. × $$\left(1+\frac{\text{Profit Percentage}}{100}\right)$$​​

Solution:

Cost Price (C.P.) of 1 lemon = ₹ $$\frac{1}{7}$$​ per lemon

Selling Price (S.P.) for a 75% profit:

S.P. = $$\frac{1}{7} \times 1.75 = \frac{1.75}{7}$$​ = ₹ 0.25 per lemon

Number of lemons to sell for ₹1 = $$\frac{1}{0.25}$$​ = 4

Thus, The vendor must sell 4 lemons for ₹1 to gain a 75% profit
