A well has 30 steps a frog inside the well wants to get out of it for every 5 steps it jumps in a day, it falls down by 3 steps.
To find : the number of day to get out of the wall by frog.
solution : as every 5 steps frog jumps in a day, it falls down by 3 steps.
so each day, frog climbs up 2 steps.
in 13 days , frog climbs up 26 steps.
in 14th day frog jumps 5 steps first then it reaches (26 + 5) = 31 steps ( frog gets out of the wall) now it can't fall down by 2 steps.
Therefore frog gets out of the wall in 14 days.
