GMAT Question of the Day: Data Sufficiency

Data Sufficiency on a bright spring day
Explanation
Statement (1) 6x is divisible by 13 for x = 13, and is not for any other prime number x. This statement alone is insufficient.

The correct answer is B, C, or E.

Statement (2) Since 6x = 2(3x), 6x/13 is also divisible by 13, and is therefore an integer. This statement alone is sufficient.

The correct choice is B.
