Question

A monkey jumps 5m every second on 60m vertical pole and falls down 2m over the next second . How many seconds will the monkey will take to climb on the pole

Answer 1

1st second: +5 mts
2nd second: -2 mts
So in two seconds the monkey climbs 3 mts.

Hence, in 38 seconds it climbs 57 mts.
In the next second, he will reach the top.
So, total time = 38+1 = 39 seconds .
