Answer:
Option c => 6160
Step-by-step explanation:
Mean salary of 40 female workers = 5200
Total salary of 40 female workers = 5200 x 40
= 208000
Mean salary of 60 male workers = 6800
Total salary of 60 male workers = 6800 x 60
= 408000
Total salary of 40 female and 60 male workers
= 208000 + 408000
=616000
Combined mean Salary
= 616000 / 100
= 6160
