In a telecom assembly factory. there are 250men and 150women..the average productivity of all works is 12 per day..the average productivity of men is 15 units per day and what is the average of women per day ??

1) 9
2) 6
3) 7
4) 8

• 15-12=3
  250*3=750
  750/150=5
  12-5=7

• Let M be Men and W be women.
  250+150=400(total)
  400*12(avg of all workers)=4800
  M/250=15==>M=3750
  for women=total-Men
  =4800-3750
  =1050
  and so divide by no of women to get average 1050/150=7(the right answer)
