Using both Statements, he might have bought one $7 book, eight $2 books, and one $1 book, or he might have bought two $7 books, two $2 books and six $1 books, so the answer is E.

Statement 1
Mr smith spent 24 dollar on bargain books
He could have bought (7dollar *3 books) + (2dollar *1book) + (1 dollar *1) book
OR
(7 dollar *2 books) + (2 dollar *4 books) + (1 dollar * 2 books) = 24 dollar
Statement 1 is NOT SUFFICIENT.
Statement 2
Mr smith buys a total of 10 books
The price tags for each of the 10 books is unknown, hence statement 2 is INSUFFICIENT.
Combining statement 1 and 2 together
The two statement together are not enough to establish a relationship for the quantity of books purchased for each price tag.
Hence all the two statements together are INSUFFICIENT.
