Question

Out of a class of 150 ,one-third opted for cricketer, two-fifth for tennis and rest for badminton. Find how many opted for badminton

Answer 1

Let the no. of students opted for badminton be x.
then,
No. of students opted for cricket=150×1/3
=50
No. of students opted for tenis=150×2/5
=60
So,
60+50+x=150
=>x=150-110
=>x=40
