A + B - AB = 200
A is the number who play soccer.
B is the number who play cricket.
AB is the number who play both.
A = 120
B = 100
120 + 100 - AB = 200
220 - AB = 200
AB = 220 - 200 = 20
20 play both.
this means that:
100 play soccer only.
80 play cricket only.
20 play both.
100 + 80 + 20 = 200
solution is:
80 play cricket but not soccer.
