. In a telecom assembly factory,there are 250men and 150 women.The average productivity of all works is 12 units per day.The average productivity of men is 15 units per day..what is the average productivity of women per day?
a)6 b)9 c)7 d)8

• Simple case of averaging:
  
  250M + 150W = 400
  Thus, 400*12 = 4800
  
  Now, 250*15 = 3750
  
  Now, 4800-3750 = 1050
  
  Thus, for 150W avg prod is : 1050/150 = 7

• total work= (250+150)x12=4800,
  men total work=(250x15)=3750,
  women total work =4800-3750=1050
  average work of women=1050/150=7 (ans)
