Answer 1

Answer:

English= 57

french =28

both = 15

Step-by-step explanation:

we can solve it using sets and functions formula.

let x be the no of people who can speak both.

let A and B be the people who can speak english and french respectively.

AUB = A+B -(Aintersection B)

100=72+43-x

100-115=-x

x=15

A only =72-15=57

B only = 43-15=28
