Question

A pirate purchased an old bicycle for $Rs.960$. He spent $20\%$ of the cost on its repair. If he wants to earn $Rs288$ as net profit on it, find profit $\%$.

• A. $50$%
• B. $40$%
• C. $35$%
• D. $25$%

Answer 1

The correct option is D $25$%

Purchase price of an old bicycle $=Rs960$

Repair cost $=20\%ofcost=20\%of960=\frac{20\times 960}{100}=192Rs$

Hence, Total cost $=960+192=1152Rs$

Given that $Profit=288Rs$

$\therefore Profitpercentage=\frac{profit\times 100}{Totalcost}=\frac{288\times 100}{1152}=25\%$
