Answer: The Total number of Students who like Milk is 12 and the total number of Students who like Tea is 9.

Explanation:

Let us start off by subtracting the number of students who like both milk and tea from the total number of students:

33-12 = 21

Rest of the 21 Students like either Milk or Tea. Now with the help of the ratio, we find the total number of students who like Milk alone:

21 x 4/7 = 12

(4 Being the ratio of students who like Milk and 7 being the total ratio of 4+3 )

12 Students like Milk while:

21-12= 9 (or) 21 x 3/7= 9

9 Students like Tea.
