Answer 1

Given:

A vegetable seller sells 8 lemons at ` 20 by buying 10 lemons at ` 20. The profit percentage of the vegetable seller is?

To find:

The profit percentage of the vegetable seller is?

Solution:

The C.P. of 10 lemons = Rs. 20

∴ The C.P. of 1 lemon = Rs. $\frac{20}{10} = Rs. \:2$

The S.P. of 8 lemons = Rs. 20

∴ The S.P. of 1 lemon = Rs. $\frac{20}{8} = \frac{5}{2} = Rs.\:2.5$

Now,

The profit percentage of the vegetable seller would be,

= $\frac{Profit}{C.P.} \times 100$

= $\frac{S.P.\: - \:C.P. }{C.P.} \times 100$

= $\frac{2.5\: - \:2 }{2} \times 100$

= $\frac{0.5}{2} \times 100$

= $0.25 \times 100$

= $\bold{25\%}$ ← option (a)

Thus, the profit percentage of the vegetable seller is → 25%.
