the nater level?​

Answer 1

ANSWER

(a) Monkey Jumps 3 steps down and 2 steps up so, in total he jumped 1 step down.Therefore , Now he is at second step and water level is at the ninth step.

Now, he will reach water level in 9−2=7 jumps.

(b) He jumps 4 steps up and 2 steps down ,so totally he climbs 2 steps up in 6 Jumps,Similarly we can divide 9 steps as follows

⇒9=2+2+2+3

After reaching the third Step, As he jumps up 3 more Steps He will reach the top step and till then there will be no more steps to climb.(Means after 3 more Jumps he will reach the top step)

Now, the number of jumps he made to reach the top =2×6+2×6+2×6+3=12+12+12+3=39 ...
