Question

In a party of 50 people, 44% like to drink coffee, 46% like to drink tea and rest prefer soft drink. Find the no. of person who like soft drink.​

Answer 1

Answer:

here,n(U)=50

number of people like to drink coffee n(C)=44%=22

number of people like to drink tea n(T)=46%=23

number of people like to drink soft drinks n(S)=?

now, n(U)=n(C)+n(T)+n(S)

=50=22+23+n(S)

=50=45+n(S)

n(S)=50-45

=5
