Answer 2

Given : A fruit seller buys 5 oranges for a rupee and sells 4 oranges for a rupee

To find : gain percent

Explanation:

cost price  of 5 oranges = Rs. 1

cost price of 1 orange = Rs. $\frac{1}{5}$

Selling price of 4 oranges = Rs. 1

selling price of 1 orange = Rs. $\frac{1}{4}$

then

profit % is

$\frac{SP - CP}{CP}\times 100 \\\\\frac{\frac{1}{4}-\frac{1}{5}}{\frac{1}{5}}\times 100 \\\\\text {taking LCM we get}\\\\\frac{\frac{1}{20}}{\frac{1}{5}}\times 100\\\\\frac{1}{4}\times 100$

= 25%

hence , The gain percent is 25%
