B. 25

C. 35

D. 45

Answer :

Given:


Total number of students are 60


Students who play cricket and tennis are 25 and 20 respectively


Students who play both the games are 10


To find: number of students who play neither


Let S be the total number of students, C and T be the number of students who play cricket and tennis respectively


n(S) = 60, n(C) = 25, n(T) = 20, n(C T) = 10


Number of students who play either of them = n(C T)


= n(C) + n(T) – n(C T)


= 25 + 20 – 10


= 35


Number of student who play neither


= Total – n(C T)


= 60 – 35


= 25


Hence, there are 25 students who play neither cricket nor tennis.
