Question

By selling 15 apples, a seller gains the selling price of 3 apples, what is his gain percent?

Answer 1

Profit %=(3/15)*100=20%

Answer 2

Answer:

The profit % is 25%.

Step-by-step explanation:

It is given that by selling 15 apples, a seller gains the selling price of 3 apples.

It means Profit of 15 apples is equal to selling price of 3 apples.

$P\times 15=SP\times 3$

$\frac{P}{SP}\frac{3}{15}$

$\frac{P}{SP}\frac{1}{5}$

It means the ratio of profit and SP is 1:5.

Let profit be x and SP be 5x.

$CP=SP-P=5x-x=4x$

Profit % is

$\frac{P}{CP}\times100=\frac{x}{4x}\times 100=25\%$

Therefore the profit % is 25%.
