Answer 1

Given:

Discount percentage = 40%

Sale price of the book = $18

To find:

Original price of the book

Solution:

Let us assume that the original price of the book as x. As per the question, there was 40% discount and the price of the book has been reduced to $18 which is 40% of the original price. That is,

$\Rightarrow40\% \times x=\ 18\rightarrow\frac{40}{100}\times x =\ 18$

$\Rightarrow x=\frac{18\times100}{40}\rightarrow x=\ 45$

Therefore, the original price of the book is $45.
