If p and q are positive integers, what is the value of p/(q^2)?

(1) p is a multiple of q^2 --> $$\frac{p}{q^2}=integer$$. If $$p=q=1$$, then $$\frac{p}{q^2}=1$$ but if $$p=2$$ and $$q=1$$, then $$\frac{p}{q^2}=2$$. Not sufficient.

(2) q is a multiple of p --> $$\frac{q}{p}=integer$$. If $$p=q=1$$, then $$\frac{p}{q^2}=1$$ but if $$q=2$$ and $$p=1$$, then $$\frac{p}{q^2}=\frac{1}{4}$$. Not sufficient.

(1)+(2) From (1) we have that $$\frac{p}{q^2}=integer_1$$ and $$\frac{q}{p}=integer_2$$. Multiply these two: $$\frac{p}{q^2}*\frac{q}{p}=integer_1*integer_2=integer$$ --> $$\frac{1}{q}=integer$$. Since we know that q is a positive integer, then $$q=1$$. Now, if $$q=1$$, then from $$\frac{q}{p}=integer$$ --> $$\frac{1}{p}=integer$$ --> $$p=1$$. Therefore $$\frac{p}{q^2}=1$$. Sufficient.

Hope it's clear.
