C

1. Nothing about R

2. Nothing about P

1&2 Because P,R,Q are positive integers Q^2=R^2 ==> Q=R ==> Q=R=P sufficient

I differ with walker's explanation

Here is my answer.

Statement 1:
Tell us nothing about R, so insufficient.

Statement 2:
Tell us nothing about P, so insufficient.

Combining Both the statements:
Statement 2 tells us Q^2 = R^2 But that does not mean Q = R.
This means Q can be equal to + R or -R.

So If Q = R then P = Q = R
However if Q = -R, then equation does not hold true.

So Question cannot be answered, Answer E.

The favorite GMAT traps: integer, non-zero, prime numbers, positive, negative, consecutive, even, odd, even consecutive - all properties that crucially restrict the set of possible numbers. :wink:

Almost said E. C b/c the stem says they are + integers.

1. P = Q
2. Q^2 = R^2




1 Insuff. R unkown
2. Q = + or - R, P unkown ->Insuff
together

P=Q= + or - R Insuff

Man! Great question. What I would call a "reverse trap".

I went with E, obviously it's a C.
