Answer:
Given: The population of town (ξ)=10000
No of people who reads newspaper A =n(A)=5400
No of persons who reads newspaper B =n(B)=4700
No of people who reads both newpapers =n(A∩B)=1500
n(A∪B)=n(A)+n(B)−n(A∩B)
=5400+4700−1500=8600
and
n(A∪B)
′
=n(ξ)−n(A∪B)
=10000−8600=1400
∴ No of persons who do read either of the papers are 1400.
A farmer bought a buffalo for ₹ 44000 and a cow for ₹ 18000. he sold
