Math’s Summer Holiday Home Work
Question 1
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. In (a) the sum (− 8) represents going down by eight steps. So, what will the sum 8 in (b) represent?

A plane is flying at the height of 5000 m above the sea level. At a particular point, it is exactly above a submarine

(ii) − 53 + … = − 53
(iii) 17 + … = 0
(iv) [13 + (− 12)] + (…) = 13 + [(− 12) + (− 7)]
