There are 100 students in a particular class. 60% students play cricket, 30% student play football and 10% student play both the games. What is the number of students who play neither cricket nor football?
- 25
- 20
- 18
- 15
Answer
Let Set A be the students playing cricket and Set B the students playing football.
Out of 100 students, 60% play cricket and 30% play football.
Set A (Cricket) = 60
Set B (Football) = 30
10% students play both cricket and football.
A ∩ B = 10
A ∪ B = A + B - (A ∩ B)
A ∪ B = 60 + 30 - 10 = 80
(A ∪ B)' = 100 - 80 = 20
The correct option is B.
