In the Awadh school Gomti Nagar, there are 500 students.

Ques - In the Awadh school Gomti Nagar, there are 500 students. 60% of the students are boys, 40% of whom play hockey and the girls don't play hockey, 75% of girls play badminton. There are only two games to be played. The number of students who don't play any game is :

A. 10%

B. 36%

C. 46%

D. can't be determined

Solution -

Total number of students = 500

Number of boys = 60% of 500

= (60/100) * 500

= 300

Number of girls = 500 - 300 = 200

40% of boys play hockey = 40% of 300

= (40/100) * 300

= 120

Girls Don't play hockey

75% of girls play Batminton = 75% of 200

= (75/100) * 200

= 150

But,

Here we don't know about how many boys are play batminton.

Since,

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.

Hence,

The correct answer is option (d) can't determined.
