Question

Find the cost price, if S.P. $=$ Rs. $1,680$ and profit $=12\%$.

Answer 1

Profit % $=\frac{S.P-C.P}{C.P}\times 100$

$\Rightarrow 12=\frac{1680-C.P}{C.P}\times 100$
$\Rightarrow 12\times C.P.=168000-100\times C.P.$
$\Rightarrow 112\times C.P.=168000$
$\Rightarrow C.P.=\frac{16800}{112}$
$\Rightarrow C.P.=Rs.1500$
