Abbot can do some work in 10 days, Bill can do it in 20 days and Clinton can do it in 40 days. They start working in turns with Abbot starting to work on the first day followed by Bill on the 2nd day and by Clinton on the 3rd day and again by Abbot on the fourth day and so ontill the work is completed fully.find the time to complete the work fully.

• abbot one day work=1/10
  bill one day work=1/20
  clinton one day work=1/40
  then 1/10+1/20+1/40=3 day work
  (8+4+2)*5/80=3*5 day
  then
  left work=1-7/8=1/8
  then 1/8-1/10 then=then work left=1/40
  then day=15+1
  then next daaaay 1/40-1/20 then this is neg
  (1/40)/(1/20)=1/2then total day 161/2
