Solution

The correct option is B 360
In the quadrilateral PQRS,
P+Q+R+S=360
120+80+60+S=360
S=100

P+extP=180 [Linear Pair]
120+a=180
a=60
Similarly,

Q+extQ=180 [Linear Pair]
80+b=180
a=100

And,
R+extR=180 [Linear Pair]
60+c=180
a=120

S+extS=180 [Linear Pair]
100+d=180
d=80

a+b+c+d=60+100+120+80

a+b+c+d=360
