Answer 1

Dear Student,

$$\begin{gathered} \mathrm{Cost}\mathrm{price}\mathrm{of}\mathrm{Calculator}=\mathrm{Rs}400 \\ \mathrm{Selling}\mathrm{price}=\mathrm{Rs}480 \\ \mathrm{Profit}=\mathrm{Rs}\left(480-400\right)=\mathrm{Rs}80 \\ \mathrm{Profit}\hspace{0.17em}\%\mathrm{age}=\frac{80}{400}\times 100=20\% \\ \mathrm{Hence},\mathrm{sarthak}\mathrm{gain}20\%\mathrm{on}\mathrm{selling}\mathrm{a}\mathrm{calculator}. \end{gathered}$$
