Explanation:

Let in office A x employee and in B y employees
If 10 employees are sent from A then employees are equal
X-10 =y+10
x-y=20 ....equation 1
If 20 employees are sent from B to A
2x=y-20
2x-y=-20 ..... equation 2
Solving 1 and 2
-x=40
X=40 taking magnitude
Putting value of x
Y=20
total=60
