One monkey climbs 6 mts and fall 3 mts in alternate minutes then time taken to climb a tree 60 meters high?

• Ans : 90 minutes
  6mt (climb) - 1min
  3mt(drop) - 1min
  So relatively he climbs 3mt in 2mins
  So in a min 1.5 for 60 mt it will be 90min

• Sorry for the wrong answer, the correct ans will be 37 min
  
  So for 54 mts it will take 54*2/3 = 36 min at 37 min he will reach top.

• 39 minutes
  
  Effective climb =3 m. in 2 minutes.
  Check nearest multiple of 3 before 60 which is 57, so in next 1 minute it can climb total 60 m.
  For climbing 57 m, time required= 57*2/3=38
  Hence in next 1 minute covering 3 m., i.e. in 39th minute, it can climb 60 m.
