Question

A frog has fallen into a pit which is 30m long every day it is climbing 3m but at night again fallen down 2m in how many days frog can escape from that pit​

Answer 1

In about 30 days, As it Gains 3m of height then falls to 2m Therfore Distance covered in 1 day = 1m. So, Dpr climbing the pit he needs to Keep on following this patrern for 30 days

Answer 2

28 days. In 26 days it will be 26 feet up the well. On the 27th day it will jump to 29 feet and slide down to 27 feet. On the 28th day it will jump 3 feet and be at the top. Of course it will probably stay there and slide down another 2 feet. Also what happens if it rests for a day or more through the exertion. Then it takes longer. What if it loses its grip and has to start again. What if it dies through starvation long before it gets to the top. Finally why doesn’t it climb the ladder - much easier and quicker.

hope it helps
