Question

A bookseller gives 8% discount on the printed price. What does a customer pay for a book priced at Rs.150?

Answer 1

Given, M.P. of a book = Rs.150
Discount = 8%
${\displaystyle \frac{\text{S.P.}}{\text{M.P.}}=1-\frac{\text{discount}}{100}}$

⇒ ${\displaystyle \frac{\text{S.P.}}{150}=1-\frac{8}{100}}$

⇒ S.P. = ${\displaystyle \frac{92}{100}}$ x Rs.150
= Rs.138
∴ Amount paid by the customer for the book = Rs.138.
