so, according to our problem p(a union b )=40 p(a)=30; p(b)=20;
so, we have to find p(a intersect b), so=30+20-40 =10prititripathi

In the given question. n(e^t)=n(e)+n(t)-n(e or t)
n(e and t)=n - neither who speak English nor Telugu=150-30=>120.
n(e and t)=n(e)+n(t)-n(e or t)
120=55+85-n(e or t)
n(e or t)=20.
n(only Telugu)=n(t)-n(e or t)=85-20 = 65.
