Divya takes 5 days to read a book. She read ¼ part of the book on first day, 20% on the second day and remaining in the next three days. She reads equal number of pages in the last three days. If she reads 66 pages on the third day, how many pages did the book contain? Correct Answer 360

Let x be the number of pages in the book.

Number of pages read on the first day = x/4

Number of pages read on the second day = 20% of x x/5

Number of pages read on the last three days = x - x/4 - x/5 = 11x/20

Given, number of pages read on third day = 66

(1/3) × (11x/20) = 66

⇒ x = 360

Hence, book contain 360 pages.
