Question 12

On selling 25 shirts, a retailer earns profit equal to the cost price of 8 shirts. What is the profit percentage?

Solution

Let cost price of a shirt = Rs. $$x$$ and selling price = Rs. $$y$$

Profit on selling 25 shirts = Rs. $$25(y-x)$$

According to ques,

=> $$25(y-x)=8x$$

=> $$25y-25x=8x$$

=> $$25y=8x+25x=33x$$

=> $$\frac{y}{x}=\frac{33}{25}$$

Let $$x=25$$ and $$y=33$$

Thus, profit % = $$\frac{(y-x)}{x}\times100$$

= $$\frac{(33-25)}{25}\times100$$

= $$8\times4=32\%$$

=> Ans - (B)
