Answer 2

Given:

John purchase 32 pens at the rate of 5 pens for rupees 22 and sold them at the rate of 4 pens for Rs 22

To Find:

calculate the profit percent of John

Solution:

Cost price of 5 pens = Rs.22

Cost price of 1 pen = $\frac{22}{5}$

Selling price of 4 pens = Rs.22

Selling price of 1 pen = $\frac{22}{4}$

$Profit\% = \frac{SP-CP}{CP} \times 100\\Profit\% = \frac{\frac{22}{4}-\frac{22}{5}}{\frac{22}{5}} \times 100\\Profit\% =25\%$

Hence The profit percent of John is 25%
