If three people can do a piece of work in 36 days. And first and second can do twice as the third. First and third can do thrice the second. Then find hopw many days will c take to do the work.

• a+b+c=1/36
  a+b=2c
  2c+c=1/36
  3c=1/36
  c=1/108
  c takes 108 days

• Since A,B,C ca n do the work in 36 days.And the efficiency of (A+B) is twice to that of C .Hence we can take it as the efficiency of all the three will be equal.(See this can not be taken as true case but can be taken as a favourable case )
  So C alone can do it in 36*3=108 days

• it taks 72 days
  2a = 2b=c
  put in a+b+c=1/36
