    1. total work is lcm of 20,30,60 means 60 units.
      A's work = 3u/d
      B's work = 2u/d
      C's work = 1u/d

      1st day A and B will work = 3+2 = 5 units
      2nd day A works with C = 3 +1= 4 units
      total two days work is 9 units..
      2 9
      2*7=14days 9*7=56units
      how many units remaining 4 units .
      then 4 unit will done by A & B in 4/5days...

      so total work done in 14+ 4/5 days
