28 steps
After every 5 steps he is going one down(3-2)
When he reaches 6step he will have done 30 jumps
He will only go 3 more steps so total 33

Answer:
13 jumps
Step-by-step explanation:
∵ The frog jumps 3 steps down and then jumps 2 steps up.
So, in two jumps the total steps it goes down = 3 - 2 = 1,
Also, the water level is At 9th step,
Since, at the last 3 step down it will not come up,
So, the steps it will cover with the speed of 1 step per two jump = 9 - 3 = 6,
1 step = 2 jump
6 steps = 12 jump
Hence, the total jumps will reach it to the water level = 12 jump + Last jump of 3 step
= 12 + 1
= 13
