Question

Find the profit or loss per cent if $CP$ is $\frac{3}{5}th$ of its $SP$.

Answer 1

Finding the profit percentage

Let the $SP$ be $₹1.$

then $CP$ will be $₹\frac{3}{5}=₹0.6$.

$$\begin{gathered} Profit=SP-CP \\ =₹(1-0.6) \\ =₹0.4 \\ Profit\%=\frac{Profit}{CP}X100 \\ =\frac{0.4}{0.6}X100 \\ =66.67\% \end{gathered}$$

Hence Profit per cent $=66.67\%$
