4. A water tank has steps inside it. A monkey is sitting on the topmost step (i.e., the
first step). The water level is at the ninth step.
i) He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will
he reach the water level?
ii) After drinking water, he wants to go back. For this, he jumps 4 steps up and then
jumps back 2 steps down in every move. In how many jumps will he reach back the
top step?
iii) 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 (b) 4 – 2 + … = 8.
