Question

Find the selling price when C.P.$=Rs.450$, profit$=12$%.

Answer 1

We know that for a certain profit;

$S.P.=C.P.+\frac{\%profit}{100}\times C.P.$

$S.P.=450+\frac{12}{100}\left(450\right)$

$=450(1+\frac{12}{100})=\frac{112}{100}\times 450$

$=\frac{112\times 9}{2}=56\times 9=504$

$\Rightarrow$ $S.P.$ $=$ $Rs.$ $504$.
