Question

How many pages of book X did Robert read on Sunday ?
Statements:
1. The book has 300 pages out of which two-thirds were read by him before Sunday.
2. Robert read the last 40 pages of the book on the morning of Monday.

• A. I alone is sufficient while II alone is not sufficient
• B. II alone is sufficient while I alone is not sufficient
• C. Either I or II is sufficient
• D. Neither I nor II is sufficient
• E. Both I and II are sufficient

Answer 1

The correct option is E Both I and II are sufficient

From I and II, we find that Robert read (300 x 2/3) i.e. 200 pages before Sunday and the last 40 pages on Monday.
This means that he read [300 - (200 + 40)] i.e. 60 pages on Sunday.
