a man,woman & a boy can do a work in 20 days,30 days & 60 days respectively.how many boys must assist 2 men and 8 women to do the work in 2 days?

• it is clear
  that job of 1 man = job of 3 boys
  job of 1 woman = job of 2 boys
  
  so 2 men = 6 boys
  8 women =16 boys
  
  
  1 boy can do work in 60 days
  so 30 boys can do work in 2 days.
  2men +8 women = 22 boys
  
  Additional boys reqd = 30-22=8 boys
