A water tank has steps inside it. A monkey is sitting on the top most step (i.e., the first step). The water level is at the ninth step .
(1) He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will he reach the water level ?
(2) 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 ?
(3) If the no. Of steps moved down is represented by negative integers and the no. Of steps moved up by positive integers , represent his moves in part 1 and 2 by completing the following; (1) -3+2-..... = -8 (2) 4-2+....... =8. In 1 the sum (-8) represent going down by eight steps. So, what will the sum 8 in 2 represent ?

(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. In (a) the sum (− 8) represents going down by eight steps. So, what will the sum 8 in (b) represent?

An escalator is moving up at a speed of 1 step per 2 seconds. A person is also moving up on that escalator. He started to walk at the rate of 2 steps per second. He reached the top of the escalator in 10 seconds. How many steps are there in that escalator?
