A girl read 2/5 part of a book in 1st day, 34% in second day and remaining page in next two days. In two days she read equal number of page. If she read 52 pages on last day, then find out how many pages did the book contain?

Correct Answer: 400

Explanation:

1st day the girl read = 40%


2nd day she read = 34 %


Remaining percentage of book = 100% - (40% +34%) = 26%


But given last two days she read equal number of pages


=> Each day she read 26%/2 = 13%


Last day she read 52 pages = 13%


13% = 52


1% = 4


=> 100% = 400


Total pages in the book is 400.
