Question

Ravi bought a bike with a marked price of Rs.40,000. The dealer gave him two successive discounts of $10\%$ and $20\%$. After he bought the bike, he spent $10\%$ of the cost of the bike on the accessories. The price should he sell the bike to earn a profit of $10\%.$ is (in Rs.)___

Answer 1

Cost of the bike = $0.9\times 0.8\times 40000$ = Rs. 28800

For Ravi total cost $=28800+(28800\times 0.1)=31680$

So, for a profit of $10\%$ he should sell the bike at $31680+(0.1\times 31680)=Rs.34848$
