Solution and Answers :


Solution :

Total = 250
Boys and Girls ratio = 2:3

Boys :-

Total boys = 100

Only Badminton = (19*100)/100=19
Only Table Tennis = (11*150)/100=11
Only Badminton = (16*100)/100=16
Badminton and Tennis = (15*100)/100=15
Badminton and Football = (17*100)/100=17
Table Tennis and Football = (15*100)/100=15
All 3 played boys = 100-93=7

Girls :- 

Only Badminton = (16*150)/100=24
Only Table Tennis = (18*150)/100=27
Only Football = (12*150)/100=18
Badminton and Tennis = (18*150)/100=27
Badminton and Football = (14*150)/100=21
Table Tennis and Football = (16*150)/100=24
