Question

a boy read 3/8 of a book on Monday and four fifth of the remainder on another day if there are 30 pages unread how many pages does the book contain​

Answer 1

If 3/8 of the book were read the first day, then 5/8 remained.

4/5 of 5/8 = 4/5 * 5/8 = 4/8

So now 3/8 + 4/8 = 7/8 have been read.

The 30 pages that remain must be 1/8 of the total.

So if p is the total number of pages:

p/8 = 30

p = 240 pages

Answer 2

The book contains 240 pages.............
