Brain Teasers Questions for Interview

A snail wants to creep on to the top of the tree 5m high. During the day it can creep up 3m but during the night it creeps down 2m. How many days does it need to reach the top?

3 Days.
First Day: 3-2=1m,
Second Day: 3-2=1m.

So, it creeped 2m at the end of the second day.
In the third day, 3 more meters it creeps to reach the peak.
