Is the measure of angle PQR in triangle PQR more than 100 %

a) PQ = QR
b) QR=PQ+PR-0.03

Was able to understand why A is sufficient but not sure about B (guessed on B and was wrong)

Could someone assist on how to determine if B is sufficient / not sufficient

option B is just giving the relation of a triangle ie length of any side of triangle is less than sum of other two sides
thus we cannot conclude about the type of triangle PQR is...

Rohit --

Assuming triangle is RQP ...the question is asking if side RP is the greatest ?

Going to the equation -- QR=PQ+PR-0.03

QR + 0.03 = PQ + PR

so this is not sufficient because PQ or PR could be the biggest side ?

On a separate note, can we assume QR is NOT the biggest side ?

Can someone explain how A is sufficient. It gives PQ=QR . Hence triangle is isosceles for which still angle Q can be greater than 100 or less

Am I reading the question correctly? "Is the measure of angle PQR in triangle PQR more than 100 %" How can an angle be measured in percentage? Can someone please explain the question? I honestly did not understand it.
