Question

(e) (-231)+79 + 511 (-399)+159+81
10. 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:
He jumps 3 steps down and then jumps back 2
steps up. In how many jumps will he reach the
water level?
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?
If the number of steps moved down is
represented by negative integers and the
number of steps move up by positive integers,
represent his moves in part (i) and (ii) by completing the following:
(a) -3+2-min=-8 (b) 4-24m=8
In (a) the sum (-8) represent going down by eight steps. So, what will the sum 8 in (b)
represent?

Answer 1

Step-by-step explanation:

1. The monkey jump down 3 steps and return go 2 steps so,3+(-2)+3+(-2)+3+(-2)+3+(-2)+3+(-2)+3
2. we know that+(-):---
3. 3-2+3-2+3-2+3-2+3-2+3-2+3
4. now 1+1+1+1+1+3
5. answer:8
