Correct Answer: 700
Explanation:
Let number of boys in the school = x
Let number of girls in the school = y
Number of students participated in the sports = 300
Out of which boys = 100
but given number of boys participated in sports = x/3
=> x/3 = 100
=> x = 300
Remaining girls = 300 - 100 = 200
=> y/2 = 200
=> y = 400
Therefore, total number of students in the school = x + y = 300 + 400 = 700
Correct Answer: 0.0625
Explanation:

Correct Answer: 100 & 4
Explanation:
Let the first number be x and the second number be y.
Given
5% of x = (25% of y) + y
=> 5x/100 = 5y/4
=> x = 25y ......(1)
and also given that, x - y = 96
=> x = 96 + y .....(2)
From (1)&(2)
25y = 96 + y
=> 24y = 96
=> y = 4
From (1)
x = 96 + 4 = 100
Hence, the numbers are 100 & 4.
