1: 30+ANGLE Q + ANGLE PRQ = 180 ......................... 1
ANGLE PRS + ANGLE PRQ = 180 ............................... 2

From 1 and 2: Angle PRS - Angle PQR = 30

2: ANGLE PQR + ANGLE PRQ = 150 ......................... 3
ANGLE PRS + ANGLE PRQ = 180 ............................... 4

From 3 and 4: Angle PRS - Angle PQR = 30

So d.

pqr == q
prq = r
prq = 180-r
rps = 90-r
rpq = 180-(180-r)-q=r-q
(1)=>qpr=30=r-q=>hence sufficient.
(2)=>q+180-r=150=>hence sufficient.
