Answer 2

as per condition
the monkey is sitted at the topmost step
∴also we can say that he is sitting in the 1st step .
now water level is at the 9th step .
∴thus to reach water the monkey has to reach 9th step
let the monkey takes y moves to reach the 9th step
now
∵ in every move he goes 3 steps down and then takes 2 steps up
∴thus we can stay that he is moving 1 step ahead in each move
as per condition
1+(y×1)=9
⇒y=8
∴the monkey reaches the 9th step in 8 moves
