A monkey climbs a 52 – m smooth pole. It climbs 6 m up in one
minute and slips
2 m down in every alternate minute. How long will it take to
reach the top of the pole?
Answer Posted / bhavya
IN 1st min it climbs-6m, and in 2nd min it slips-2ms
i.e = 1 min- 6m =6m
2 min- (6m-2m)=4m
.'. in every 2min it can climb= 10m (6m+4m)
3 min- 6m (10m+6m) =16m
4 min- 4m (16m+4m) =20m
5 min- 6m (20m+6m) =26m
6 min- 4m (26m+4m) =30m
7 min- 6m (30m+6m) =36m
8 min- 4m (36m+4m) =40m
9 min- 6m (40m+6m) =46m
10 min- 6m (46m+6m) =52m
and in last min there is no chance to slip
So the ans is = 10min
