Answer:
The required ratio is 4:3
Explanation:
From the above question,
They have given :
The average marks of the students in four sections A, B, C, and D together is 60%.
The average marks of the students of A, B, C and D individually are 45%, 50%, 72% and 80% respectively.
If the average marks of the students of sections A and B together is 48% and that of the students of B and C together is 60%.
Here we need to find the ratio of number of students in sections A and D
Since the average marks of sections B and C together are equal to the average marks of all the four sections (i.e., A,B,C and D).
Therefore the average marks of the remaining two sections A and D together will also be equal i.e., 60%
Hence, the required ratio is 4:3.
