Question

A shopkeeper purchased a calculator for Rs. $650$. He sells it at a discount of $20\%$ and still makes a profit of $20\%$. Find marked price.

Answer 1

Price of Calculator = 650

$D=20$

$=\frac{1}{5}\times 650=130$

Cost of Calculator after discount

$=650-130=520$

$P=20$

$\begin{array}{c}=\frac{1}{5}\times 520=104\\ \\ S.P.=C.P.+P\\ \\ =520+104\Rightarrow 624\\ \\ MP=SP+D\\ \\ =624+130=754\end{array}$
