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**

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 .

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**

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
