Answer:
(i) students playing cricket= 45
to find= no. of students playing hockey
90/360 x total students = 45
total students= 45 x 360/90=45x 4 =180
to find no. of students playing hockey we have to find no of students playing tennis
360 - 240 = x + (x- 20 )
120 = 2x -20
2x = 120 +20
2x = 140
x = 140/2 = 70
no. of students playing tennis = 70/360 x 180 = 35
no. of students playing hockey= x - 20= 70 - 20= 50
50/360 x 180 = 25
(ii)students who play badminton= 20/360 x 180=10
students who play basketball=70/360 x 180 = 35
sum = 35 + 10 = 45
students who play football = 60/360 x 180= 30
students who play tennis = 35
sum = 30 + 35 = 65
difference in their sum = 65 - 45 = 20
