The price of a notebook is 20% less than the price of a book. By what percent is the price of the book higher than the price of
TiliK225 [7]

The price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Let x is the price of the book

And y is the price of the notebook,

Then,

y = x- 0.20x = 0.80x

x = (1/0.80)y

x = 1.25y

So x is 1.25 or 125% higher than the, y

Thus, the price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.
