Question

In a quadrilateral pqrs among q is twice the angle p. angle r is thrice the angle p. the value of angle r is 150 .what is the sum of angle q and angle s

Answer 1

r=150 r=3p p=r/3 =50 q=2p
p+q+r+s=360
50+q+150+s=360
q+s=360-200
=160 Ans

Answer 2

r=3p= 150
p=150/3=50
q=2p=2*50=100
r+p+q+s=360
150+50+100+s=360
300+s=360
s=360-300=60
q+s=100+60=160
