24 minutes and 40 seconds.
A monkey will climb a distance of 4m in every 2 minutes
(lets call it 1 cycle of climbing 6m and slipping 2m)
so it will take a total of 12 such cycles for it reach 48m
i.e. 24 minutes.
now it has to cover another 4 meters to reach the top.
So
it covers 6m in 1 minute i.e 6m in 60 sec.
so it covers 1 m in 60/6 sec i.e 10 sec.
so it covers 4 m in 10*4=40 sec.
So in total it takes 24 minutes and 40 seconds.
