I feel the answer should be E.

Eg. 1) you can have 23 books. This will satisfy both statement 1 & 2

As you can make 3 stacks of X books where X =7 and you will have 2 books left. You can also have 3 stacks of Y books where Y = 7 and have 2 books left.

Check the same with 42 or any multiple of ((3*7*X)+2) and it will also satisfy both the given statements.

Pls let me know if my answer is right.
