Question

A water tank has steps inside it. A monkey is sitting on the topmost
step (ie, the first step). The water level is at the ninth step.
a) He jumps 3steps down and then jumps back 2 steps up. In how many
jumps will he reach the water level?
b) After drinking water, he wants to go back. For this, he jumps 4steps up
and then jumps back 2steps down in every move. In how many jumps will
he reach back the top step?
c) if the number of steps moved down is represented by negative integers
and the number of steps moved up by positive integers, represent his
moves in part(i) and (ii) by completing the following;(a)-3+2.......=-8 (6)
4-2+.....=8. In (a) the sum (-8) represent going down by eight steps. So,
what will the sum 8 in (b) represent?

Answer 2

Answer:

a) He jumps 3 steps down and jumps back 2 steps up. Following number ray shows the jumps of monkey:

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

nth jump = 5 + 3 = 8 steps Tenth jump = 8 – 2 = 6 steps

Eleventh jump = 6 + 3 = 9 steps

He will reach ninth steps in 11 jumps.

b)He jumps four steps and them jumps down 2 steps. Following number ray shows the jumps of monkey:

Thus monkey reach back on the first step in fifth jump.  (iii) (a) 3  2  3  2  3  2  3  2  3  2  3  2  3  2  3  2  8

(b) 4  2  4  2  4  2  4  2  8

Thus, sum 8 in (b) represents going up by eight steps.
