11. Is n an integer greater than 4?

(1) 3n is a positive integer.

(2) n/3 is a positive integer.

Dear

Ravithj,

I'm happy to respond.

First of all, my friend, this post is wildly miscategorized. This question should be posed in the "quantitative section", with the other DS questions.

Because it's a simple question, I will answer.

Statement #1: From this first statement, it's not even guaranteed that n is an integer --- for example, n = 5/3 would work as possible value. But n

could be an integer greater than 4, so from this statement, alone and by itself, we can draw no conclusion.

Insufficient.

Statement #2: From this statement, we know that n must be an integer and a multiple of 3 --- n could be 3, 6, 9, 12, etc. Most of those are integers greater than 4, but 3 is less than 4. From this statement, alone and by itself, we can draw no conclusion.

Insufficient.

Combined statements: Both n = 3 and n = 6 are consistent with both statements. The first gives a "no" answer to the prompt, and the second, a "yes" answer. Even with the information of both statements, we are not in a position to give a definitive answer to the prompt question. Both statements combined are

Insufficient.

Answer =
