Question

The monkey climbing up of a pole ascends 10 metres and slep down 2 metres in alternate minutes. If the pole is 57 metres high, how long will take him to reach the top of pole?

Answer 1

HEY MATE,
Here is your answer
______________________________

The monkey climbs up 10m in 1 minute and slept 2m in another.

So,in 12 minutes he climbs, 6(10) - 6(2) = 60-12 = 48m.

And, in 13 minute he climbs 10m again and reaches height of 58m and accomplishes his target.
______________________________

We are just asked when he'll reach the height so we don't need to observe 14 minute in which he'll slip 2m again.

Hope this helps!!!
