Question

A firm earns ₹50 and donates ₹20 to charity. Then, _____ percentage of the earning is donated towards charity.

• A. 20%
• B. 30%
• C. 40%
• D. 45%

Answer 1

The correct option is C 40%

Earning = $₹50$
Amount donated by the firm = $₹20$

You know,
Percentage is calculated as :
$Percentage=\frac{Part}{Whole}\times 100$

∴ Percentage donated $=\frac{20}{50}\times 100$
$=\frac{2}{5}\times 100$
$=40\%$

So, the firm donates $40\%$ for charity.
