Each chapter can have variable number of pages. The number of pages in each chapter is not same

INSUFFICIENT

(2) Each of the first 3 chapters has more pages than each of the other 12 chapters in the book..

Good to know but how does it helps us. The number of pages can be X in the first 3 chapters and Y in the next 12 chapters

We cannot reach a a definite number to deduce what is 1/3 of (x+y)

INSUFFICIENT

MERGING BOTH STATEMENT

Again insufficient , because we still not know the total number of pages in the book

ANSWER:- E
