Hi all,

had a little trouble with this one. A brief explanation would be appreciated. Thanks!

FYI, I took this from Zuleron's list of 198 gmat prep questions. The answer is D

123) If n is multiple of 5, and n = p2q where p and q are prime, which of the following must be a multiple of 25?

a. p2
b. q2
c. pq
d. p2q2
e. p3q
