There are many benefits to timing your practice, including:

The question is just badly written then. I have the same answer as venksune
5/12--> remainder is 5
13/12--> remainder is 1
It's obvious the question is either badly written or there is a typo in the question itself _________________

If n is a prime number greater than 3, what is the remainder when n is divided by 12?

A)0 B)1 C)2 D)3 E)5

Please give details of your solution.

If I were to take a guess, I would say that n should be replaced with n^2. Now try the problem. The proof is a little challenging, but not hard (this is a dumb GMAT question because all you have to do is try one number and see what the remainder is). _________________
