Question

if losss on selling a book is rupee 25 percentage and th cost price is rupees 375 find the selling price of the book.

Answer 1

Cost price of book = Rs.375
Loss percentage = 25 %
So, Selling price of book = $\mathrm{cost}\mathrm{price}\mathrm{of}\mathrm{book}-\mathrm{cost}\mathrm{price}\mathrm{of}\mathrm{book}\times \frac{25}{100}$
$$\begin{gathered} =375-375\times \frac{25}{100} \\ =375-\frac{375}{4} \\ =\frac{1500-375}{4}=\frac{1125}{4}=281.25 \end{gathered}$$
So, selling price of book = Rs.281.25
