In the diagram above, triangle PQR has a right angle at Q. What is the ratio of the area of triangle PQS to the area of triangle RQS?
(1) Line segment QS is perpendicular to PR and has a length of 12.
(2) PQR has a perimeter of 60.

(1) Line segment QS is perpendicular to PR and has a length of 12.
We need a length of both PQ and QR to determine the ratio. (Insufficient)
(2) PQR has a perimeter of 60.
We don't know the lengths of both PQ and QR to determine PR and the ratio of two triangles. (Insufficient)
Combining both,
The lengths of PQ and QR is still unknown.
Answer is E

Area PQS: Area SQR = PS : SR
1. Triangle PQS & SQR is similar. So, PS* SR = QS^2 = (12)^2 = 144
But we need PS : SR.. Insufficient.
2. Perimeter = 60.. Cannot derive any value from this.. Insufficient.
Together, PQ+QR+PS+SR = 60
PQ+QR+PS+(144/PS) = 60.. But, no info of PQ, QR..Insufficient
