 Hello and welcome to the session, let us understand the following question which says, a water tank has steps inside it, a monkey is sipping on the topmost step that is the first step, the water level is at the 9th step, he jumps 3 steps down and then jumps back 2 steps up. In how many jumps will he reach the water level? Now let us first see the diagram. Now we have 9 steps and the current position of monkey is this, monkey is sitting at the first step and he has to read the 9th step. Now first he jumps 3 steps down, so from 1 when he jumps 3 steps down he will reach on the 4th step. Now again he jumps back 2 steps up, so from 4 when he jumps back 2 steps that is 4 minus 2, so he reaches on the 2nd step. Now from 2nd step when he jumps down the 5th, on the 5th step he reaches here, he jumps down the 3 steps. Now from 5th step he jumps back 2 steps up, so he reaches again on the 3rd step. From 3rd steps he jumps down 3 steps, so he reaches on the 6th step and from 6 steps he jumps back 2 steps that is 6 minus 4, so he reaches on the 4th step. Now from 4th step he jumps down 3 steps, so he reaches on the 7th step. Now he again jumps back 2 steps up, so from 7th step he reaches on the 5th step. Now from 5th step he jumps down 3 steps, so he reaches on the 8th step and from 8th step he jumps back 2 steps, so 8 minus 2 he reaches on the 6th step. And now from the 6th step he finally reaches when he jumps back 3 steps, so he reaches 9 steps. Now the monkey finally reaches the 9th step, but to find in how many jumps will he reach the water level and our water level is at the 9th step. So now counting the number of steps we see that 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, therefore required number of jumps are 11 jumps. So let us write the answer, required number of jumps is equal to 11 jumps. I hope you have understood this question, bye and have a nice day.
