Answer:
Let
No of student play cricket( C) = 30
No of student play tennis (T) = 20
Total no student ( C u T ) = 35
We know formula
n(A u B) = n(A) + n(B) - n ( A n B)
35 = 30 + 20 - n( C n T )
35 - 50 = - n( C n T)
-15 = - n( C n T)
C n T = 15
No of student play both game ( Cricket & Tennis ) = 15
Hence options C is correct
