Answer 1

Answer:

Then, if 10 students are transferred from a to b, the number of students are equal. Similarly, if 20 students are sent from hall B to hall A, then the number of students in Hall A would be twice that of the students in Hall B. or a = 100. Therefore there are 100 students in Hall A and 80 students in Hall B.
