At the start of the sixteenth day,this makes it clear that the frog has only climbed for 15 days.
15days×3m=45 m
The total distance if he didn't slip down for some nights.
45m-29m=16m
Since 29m is the total distance the frog climbed including the distance he fell back.
16m÷4m=4days
Divide by the distance he fell,each night he fell asleep.
The answer is 4 days.
