Question

A monkey starts climbing up patri 20 feet tall each are it hops 3 feet and slips back to feed how much time would it take the monkey to reach the top

Answer 1

Answer:

17 jumps.

Reasoning:

3 feet up and 2 feet down with each jump (and each negative slip). So in 17 jumps he goes nett 17 feet up but in the eighteenth jump it is 17+3 feet before he slips down so he has crossed the 20' mark in 17th jump.
