A monkey climbs a 60 m high pole.
In the first minute, he climbs 6 m and slips down 3 m in the next minute.
Calculation:
According to the question
For 1st min, he climbs 6 m and comes down 3 m in 2nd min
Effectively in 2 min, he climbs 3 m.
In 1 min, he climbs (3/2) m
So, in 36 mins he climbs = (3/2 × 36) = 54 m
So, in 37th min, he climbs the next 6 m.
∴ The required value is 37 minutes.
