George has a total of B books in his library, 25 of which are hardcover fiction books. What is the value of B?
(1) 40 of the B books are fiction and the rest are nonfiction
(2) 60 of the B books are hardcovers and the rest are paperbacks
Statement 1:-
Total fiction books= 40
Hardcover fiction books= 25
So, paper-cover fiction books= 15 (40-25)
Since the total books is B and and fiction books are 40. Non fiction would be (B-40)
We don't know the value of non-fiction books (both hard cover and paper cover)
Not sufficient.
Statement 2
Hardcover books= 60
Fiction and Hardcover books= 25
So, non fiction hardcover books are= 35 (60-35)
Just as in statement 1, this statement does not give us the number of paper-cover book (both fiction and non fiction)
Not sufficient.
Combining both statements, we do not get the answer as we do not know the number of non-fiction and paper-cover books.
E is the answer
