Question

He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will he reach the water level?​

Answer 1

the step he is on after each jump . for example: first jump = 1+3=4, second jump = 4-2 =2 steps and so on.when you reach the top then stop and count the number of jumps made.

Monkey jumps 3 steps down and then back 2 steps up . The jumps of monkey can be represented as :

First jump = 1 + 3 = 4 steps

Second jump = 4 - 2 = 2 steps

Third jump = 2 + 3 = 5 steps

Fourth jump = 5 - 2 = 3 steps

Fifth jump = 3 + 3 = 6 steps

Sixth jump = 6 - 2 = 4 steps

Seventh jump = 4 + 3 = 7 steps

Eighth jump = 7 - 2 = 5 steps

Ninth jump = 5 + 3 = 8 steps

Tenth jump = 8 - 2 = 6 steps

Eleventh jump = 6 + 3 = 9 steps

Monkey will reach ninth step in 11 jumps .

Answer 2

Answer:

Monkey will reach the water level in 11 jumps.

Step-by-step explanation:

Monkey is sitting on the first (topmost) step .It is given that monkey jumps 3 steps down and then jumps back 2 steps up. It is given in the question that the water level is at the ninth step.

To calculate when he reaches the ninth step:

• 1st jump= 1+3=4
• 2nd jump=4-2=2
• 3rd jump=2+3=5
• 4th jump=5-2=3
• 5th jump=3+3=6
• 6th jump=6-2=4
• 7th jump=4+3=7
• 8th jump=7-2=5
• 9th jump=5+3=8
• 10th jump=8-2=6
• 11th jump=6+3=9

Therefore, Monkey reaches the water level in 11 jumps.
