Answer 1

Dear student,
$$\begin{gathered} CostPriceofbook=Rs1500 \\ Overheadexpenses=Rs500 \\ TotalCostPrice=Rs1500+500=Rs2000 \\ SellingPrice=Rs2400 \\ Profit=SP-CP \\ =2400-2000 \\ =Rs400 \\ P\%=\frac{P}{CP}\times 100 \\ =\frac{4\cancel{00}}{2\sout{0}\cancel{00}}\times 10\sout{0} \\ =20\% \end{gathered}$$
