Question

A man gains 20% by selling an article for a certain price. If he sells it at double the present selling price, the percentage of profit will be:

• A. 40
• B. 100
• C. 120
• D. 140
• E. 145

Answer 1

The correct option is D

140

Let C.P = Rs. x. Then, S.P = Rs. (120%of x) = Rs. $\frac{6x}{5}$

New S.P = Rs. $\left(2\times \frac{6x}{5}\right)$ = Rs. $\frac{12x}{5}$

Profit = Rs. $\left(\frac{12x}{5}-x\right)$=Rs. $\frac{7x}{5}$

$\therefore$Profit % = $\left(\frac{7x}{5}\times \frac{1}{x}\times 100\right)\%=140\%$
