in a group of 100 people's, 60 people's like to play cricket, 20 people's like to play both cricket and tennis. how many people like to play tennis but not cricket?

Answer 1

I think it's 40. 20 people like to play cricket and tennis and 60 people like to play cricket. 60-20=40, 40 people who only likes to play cricket. 40(t)+20(c&t)=60, 100-60=40. Hence, 40 people like to play tennis only.
