Question

2) A monkey is trying to reach the top of a pole of height 100m. In each minute it covers a distance of 30m but slips 20m downwards. In how many minutes will it reach the top?​

Answer 1

It will take the monkey 10 minutes

Explanation:

The monkey is going 30 m per minute, but then slips down 20, 30-20= 10, so the monkey is going up the pole at 10 m per minute

100m / 10m is 10 so it takes the monkey 10 minutes to get to the top.
