If they talk about prime factors of N, shall we take N as a positive integer? If yes, then (1) alone is sufficient to answer the stem.ketkoag wrote:If N's prime factors are 2 and 3, N=?
1) N<9
2) N has 12 factors.
For (2) with the same intention (N as a positive integer), following are the ways in which N could have 12 factors:
N = (2^1)*(3^5), N = (2^2)*(3^3), N = (2^3)*(3^2), N = (2^5)*(3^1), hence it is alone not sufficient.
Go for A.
