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)
