Answer:
602 pages
Explanation:
Given that he read his book on 3 different weeks in the manner;
week 1 - 234 pages
week 2 - 234 pages
week 3 - 100 pages less than he read on week 2
This means that the number of pages read on week 3
= 234 - 100
= 134 pages
Hence the total number pages in the book
= 234 + 234 + 134
= 602 pages
