Question

If selling price is doubled, the profit triples. Find the profit percent :

• A. 66(2/3)%
• B. 100%
• C. 105(1/3)%
• D. 120%
• E. None of these

Answer 1

The correct option is B

100%

Let C.P be Rs. x and S.P be Rs. y. Then , 3(y - x) = (2y - x) $⟹$ y = 2x

Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x

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