1. p = q we know nothing about r so insufficient
2. we know nothing about p so insufficient

together yes..the answer would be no if one can be a negative but the question states they are all positive

q^2 = r^2 q and r are positive so the numbers are the same..and p = q so they are all the same

C, very easy unless somebody says there's a trick in this question.

Statement 1:
P=Q

We have no idea what the value of R is.

INSUFFICIENT

Statement 2:
Q^2 = R^2

We have no idea what the value of P is

INSUFFICIENT

Statement 1 and 2:

Because the problem states that the P, Q, and R are positive integers, we know that Q and R are positive integers.

Because we know the value of Q we must also know the value of P.

SUFFICIENT

(Note that Q^2 = R^2 would have made this INSUFFICIENT if the problem had not specifically mentioned that we were dealing with positive integers)
