A to B 10 students are sent.
B to A 20 students are sent.
There is double students of A from B.
Means 10 doubles to 20
It's simple there is 20 students in A.
And 10 students in B.
When we equally divided them then each class has 15 students.

Answer:
100 students in Class A
80 Students in Class B
Step-by-step explanation:
Let say students in classrooms A = A
Let say students in classrooms B = B
A - 10 = B + 10
=> A = B + 20 - eq 1
A + 20 = 2(B-20)
=> A + 20 = 2B - 40
=> A = 2B - 60 - eq 2
Equating Both
2B - 60 = B + 20
=> B = 80
A = 100
100 students in Class A
80 Students in Class B
