Question

A man buys a book for Rs. 25 and sells it for Rs. 30. What is his gain percentage?

• A. $20\%$
• B. $25\%$
• C. $33\frac{1}{3}\%$
• D. $16\frac{2}{3}\%$

Answer 1

Answer: (A)

$20\%$

Given that, a man buys a book for $Rs.25$ and sells it for $Rs.30$.

Hence, $C.P.=Rs.25$ and $S.P.=Rs.30$.

We know that,

Profit$\%=\left(\frac{S.P.-C.P.}{C.P.}\right)\times 100$

$=\left(\frac{30-25}{25}\right)\times 100$

$=20\%$

Hence, the required gain percentage is $20\%$.
