Everyday frog jump 5 meters but falls 4 meters down,
means net upward = 1 meter in 1 day
It will take 15 days to jump up to 15 meters
after that, final jump = 5 meters, frog is out of the well, then no slipping .
So, total number of days = 15 +1 = 16 days

Frog jumps 5 meters but fall 4 meters means 1 meter each day
last jump will be made at once and it will be out of well
20-5=15
15 meters 15 days last jump one day
16 days
