Answer:
325
Step-by-step explanation:
Given total number of students = n(U) = 600
Number of students taking Tea = n(T)= 150
Number of students taking Coffee = n(C)= 225
Number of students taking both tea and coffee = n(T∩C) = 100`
Number of students either taking tea or coffee
n(T∪C) = n(T) + n(C) - n(T∩C)
= 150 + 225 - 100
= 375 - 100
= 275
Now Number of students neither taking tea nor coffee
= 600-275
= 325
