Question

A man buys a book for 300 rupees and sells it at a gain of 30 rupees. Find the gain percent?

• A. 5%
• B. 10%
• C. 1%
• D. 7%

Answer 1

The correct option is B

10%

CP = 300 rupees

Gain = 30 rupees

$\therefore$ Gain % = $\frac{\text{Gain}}{\text{CP}}\times 100=\frac{\text{/}30}{\text{/}{300}_{\text{/}10}}\times \text{/}{100}^{10}=10$ %
