Hello,

The following is a data sufficiency problem from a GMAT practice exam I recently took. I'm unable to come up with a strategy for solving this problem, and would like to know what mathematical concepts I need to use in order to get this.

So, I'm not looking for the answer, necessarily. I'm more interested in what the approach should be for solving this problem.

Any help would be appreciated.


Thanks,
Artis

If the prime numbers p and t are the only prime factors of the integer m, is m a multiple of p^2 * t?

(1) m has more than 9 positive factors
(2) m is a multiple of p^3

a. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
b. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
c. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
d. EACH statement ALONE is sufficient
e. Statements (1) and (2) together are not sufficient
 
Frankly, I have a very hard time knowing what exactly the question is.

Know that: M=6, p=2 & t=3 then 6 is not a multiple of p<SUP>2</SUP>t.
 
GMAT Questions

pka - you have to be familiar with GMAT questions, specifically data sufficiency, to answer this.

The question is asking what statements are necessary to answer the subject question. So, we have to determine whether statement 1 is sufficient by itself, or statement 2 is sufficient, etc.

Did that help?
