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.
