Question

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

• A. $66\frac{2}{3}$
• B. $100$
• C. $105\frac{1}{3}$
• D. $120$

Answer 1

Answer: (B)

$100$

Let C.P. be $Rs.x$ and S.P. be $Rs.y$.
Then, $3(y-x)=(2y-x)\Rightarrow y=2x$.
$Profit=Rs.(y-x)=Rs.(2x-x)=Rs.x$.
$\therefore Profit$ % $=(\frac{x}{x}\times 100)$% $=100$%
