8 men can complete a work in 5 days. 12 women can complete
in 10 days and 10 children in 24 days. 1 man, 1 woman and 1 child
started the work. In how many days will the work get completed if
the man did twice the work as woman and also twice the work as
child?

• 1men can complete 1/40 in 1 day,1w can complete 1/120 in 1 day,
  1c can complete 1/240 in 1 day.
  let x be work
  man do 2x, women do 1x, child 1x
  ratio of their works is 2:1:1
  so...half work is done by man and rest was done by child and women
  1/2(1/40)+1/2(1/120+1/240)
  1/80+1/240+1/480
  9/480
  53.3 days
