PSQ form a right triangle with S as the Right angle, P as the bottom angle and Q as the top angle.

PSR form a right triangle inside PSQ. The measure of angle PRS is how many degrees greater than the measure of angle PQR.

No other information is given.

1)The measure of angle QPR is 30

2)The sum of PQR and PRQ is 150.

Answer: D (each statement alone is efficient)

D can be worked out in one of the interpretation of the question. In another interpretation it could be tricky. See attached illustration for explanation. Thanks.
