Answer 2

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
