Question

A trader purchased an old bicycle for $Rs.480$. He spent $20\%$ of the cost on its repair. If he wants to earn $Rs144$ as net profit on it, find profit $\%$.

• A. $50$%
• B. $25$%
• C. $75$%
• D. $40$%

Answer 1

Answer: (B)

$25$%

$CP$ of an old bicycle $=480$

Cost on repairs $=480\times \frac{20}{100}=96$

Total CP $=480+96=576$

Profit $=144$

Profit $\%=\frac{144}{576}\times 100=25$
