Question

A book is published in three volumes, the pages being numbered from 1 onwards. The page numbers are continued from the first volume to the second volume to the third. The number of pages in the second volume is 50 more than that in the first volume, and the number pages in the third volume is one and a half times that in the second. The sum of the page numbers on the first pages of the three volumes is 1709. If n is

Correct answer: 17

Let the number of pages in volume-1 be x Number of pages in second volume = x +50 Number of pages in third volume = 3 2 (x+50) Moreover 1+(x+1)+(2 x+51)=1709 3 x+53=1709= x=552 So n =552+602+903=2057 So n =11^2 17 Hence largest prime factor of n =17
