average salary of all employees = 5000
Let the no. of workers be x
then workers total salary = 2500 into x
managers total salary = 5 into 6000 = 30000
total salary of all = 30000 + 2500x eq. 1
total employees = x + 5
so, total salary of all employees = (x+5) into 5000 eq.2
equating 1 and 2
30000 + 2500x = 5000x + 25000
2500x = 5000
x = 5000/2500 = 2
so there are 2 workers
