Question

Bala sells a car at $5$% profit for $Rs.210000$ If he sells it at $Rs.218000$ then what will be his profit percentage?

Answer 1

Profit$=5\%$

$105\%\times x=210000$

$\frac{105}{100}\times x=210000$

$x=200000Rs$

Now

Let new profit percentage be p

$\frac{100+p}{100}\times 200000=218000$

$100+p=\frac{218}{2}$

$100+p=109$

$p=109-100$

$p=9$

Hence the profit percentage $=9\%$
