Q3 of 59 Page 147

Hari reads 22% of the pages of a book on the first day, 53% on the second day and 15% on the third day. If the number of pages remaining to be read is 30, find the total number of pages in the book.

Given: % of pages read on first day = 22%


% of pages read on second day = 53%


% of pages read on third day = 15%


Total pages read = (22 + 53 + 15)% = 90%


Pages left to read = 10 %


According to the question,


10% of pages = 30


⇒ 100% of pages = 300


Hence, total pages in the book = 300
