(d)20

Explaina: Total people, X = 100
Works in office, Y = 63
Works in factor, Z = 57
Both = (Y+Z)-X
= (63+57)-100
= 120 - 100
= 20

no of people working in office p(o)=63
no of people working in factory p(f)=57
total no of people working in an organization p(o union f)=100
no of people who work in both p(o intersection f)=?
therefore, p(o union f)=p(o)+p(f)-p(o intersection f)
p(o intersection f)=p(o)+p(f)-p(o union f)
p(o intersection f)=63+57-100
p(o intersection f)=20
