Q. One monkey climbs a poll at the rate of 6mts/min and fell down 3mts in the alternately. Length of the poll is 60 mts , how much time it will take to reach the top?
Option
a. 31
b.33
c.37
d.40

• c. 37
  
  In 1st(odd minute) minute monkey climbs = 6m
  In 2nd minute monkey falls = 3m
  
  So, In every 2minutes it only climbs = 6m-3m = 3meters.
  
  S0, 2min = 3meters.
  2*18 = 3*18
  36min= 54meters
  In 37th(odd minute) minute, it climb 6m = 54 +6 = 60meters.
  
  So, in 37th minute it climbs 60 meters to reach top.
