250 men and 150 women working in a factory,having an average productivity of 12 units per day.average productivity of men is 15 units per day,what is the average productivity of women per day?

• sum of 400 people(250m+150w)= 400*12=4800
  sum of 250 men is 250*15=3750
  sum of 150 women=4800-3750=1050
  therefore 1050/150=7 units per day..
  hence ans is 7 units per day

• [(250*15)+(150*x)]/(250+150)=12
  so, x=7

• (15+x)/2=12
  x=9units answer

• Total Productivity = (12*400) units per day
  Total Productivity of men = (15*250) units per day
  Total Productivity of Women = (12*400) - (15*250) units per day
  Average productivity of women = Total Productivity of Women / 150
  = 7 units per day

• 250+150=400*12
  4800-250*15=1050
  1050/150=7

• Let avg. productivity of women be x.
  Therefore,
  (150x+250*15)/(250+150) =12
  solving we get x=7.

• 250*15 + 150*x = 400*12
  
  then x=7

• dear frns pls explain,, it is given avg prod of MEN . this means it is for all men then why multiply it with 250?

• 15 units are the average product of men hence total productivity of mens are 250*15
• 9 years agoHelpfull: Yes(0) No(0)
• short cut:
  150 corresponds to (15-12)=3
  250 corresponds to (250*3)/150=5
  therefore 12-x=5
  x=7 units per day
