A boy readth of a book on one day and th
2/7th
and the 4/5th remainder on another day. If there were
12 pages unread, How many pages in the book.​

Answer 1

Answer:

imagine, total pages as x

3/8 th of the book was read on the first day.

so, there are 5/8th of the pages left.

on the second day, (4/5)(5/8) = (4/8)

totally, (3/8)+(4/8) = (7/8)th of the pages were completed and (1/8)th of the book is left which is given as 30.

(1/8)(x) = 30

=> x= 240.

so, totally, the book contains 240 pages.
