Question

The question goes like this:

a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?

Answer 1

You read 30 pages of the book.

You have 90 pages left.

Explanation:

120 total pages

⇒ 120 = 100%

`(1)/(4)` pages have been read

⇒
`(1)/(4)` = 25%

`(3)/(4)` remaining

⇒
`(3)/(4)` = 75%

120 x .25 = 30 pages read

120 x .75 = 90 pages unread

30 + 90 = 120

Answer 2

You have 90 pages left.

Explanation:

1/4 × 120 = 30 pages read

Therefore

120- 30

=90 pages left to read
