(1) P = Q
(2) Q^2 = R^2

assuming the above conditions:

Statement 1: No info about R ---> INSUFF

Statement 2: No info about P ---> INSUFF

Together, either Q or R could be -ive or the square root of a perfect square. INSUFF

Also got E.

Both statements leave the possibility of P, Q and R being either -ve or +ve.

E seems correct !

ST 1 P=Q says nothing about R
INSUFF

ST 2 Q^2 = R^2 implies Q = R or Q = -R
INSUFF

Combined is also INSUFF

I thought E too.. This question is from the sample pdf at this site and the OE was

C. Statement (1) tells us that P and Q are equal, but nothing about R; not enough. Statement (2) tells us that Q and R are equal (they are both positive) not enough again.

I got C. Question says all are +ve. So they must be equal if both statements are true.

(C). Since all of them are positive, the values in (2) have to have to same sign.
