Answer 2

Answer:

: 9 people like both cold drink and hot drink.

Step-by-step explanation:

Let A = Set of people who like cold drink

And, B = Set of people who like hot drink

Given,

n(A∪B)=60

n(A)=27 and n(B)=42

n(A∩B)=n(A)+n(B)−n(A∪B)

n(A∩B)=27+42−60=9

Therefore, 9 people like both cold drink and hot drink.
