IMO C.

What is the OA?

Statements 1 and 2 together give us all the angles for the scalene triangle. To find the angle in question, substract 180 from its supplement.

In my opinion correct answer is D - Each alone sufficient.

Let angle PRS = x, angle PQR = y question x-y = ?

Statement 1: angle QPR = 30

angle PRQ = 180-x

in Triangle PQR 30+y+180-x = 180 => x-y = 30 Suff

Statement 2: y+180-x = 150 => x-y = 30 Suff

Hence answer D

Experts, please comment.
