Total number of students = 500
Number of boys = 60% of 500
= (60/100) * 500
Number of girls = 500 - 300 = 200
40% of boys play hockey = 40% of 300
= (40/100) * 300
Girls Don't play hockey
75% of girls play Batminton = 75% of 200
= (75/100) * 200
Here we don't know about how many boys are play batminton.
we don't have information that wether the rest of boys playing batminton or not. So we can't determine the total no. of students who are not playing any of the two games.
The correct answer is option (d) can't determined.Thank you
