(1) They bought a total of 10 books.
(2) The price of for the magazine is $5.
A. Statement (1) ALONE is sufficient but Statement (2) ALONE is not sufficient.
B. Statement (2) ALONE is sufficient but Statement (1) ALONE is not sufficient.

[quote="arjtryarjtry"]Tom and Mary bought some books and magazines. The price for each book is x dollars and the price for each magazine is y dollars. If Tom spent a total of $50 and Mary spent a total of $100, x=?
(1) They bought a total of 10 books.
(2) The price of for the magazine is $5.

Let the number of books purchased = a and the magazines purchased = b
Hence you can write the equations ------- ax +by = 50 + 100 = 150

S1. Tells you that a = 10
S2. y = 5

Now we have three equations but four unknowns

IMO E

agreed
small correction a+b = 10
