 3. A water tank has stepped inside it. A monkey is sitting on the topmost step (i.e., the first step). The water level is at the ninth step. QA. He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will he reach the water level? 🔘 7 jumps 🔘 8 jumps 🔘 9 jumps 🔘 10 jumps 🔘 11 jumps
 3/ QB..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? 🔘  4 jumps 🔘  5 jumps 🔘 6 jumps 🔘  7 jumps 🔘  8 jumps
 5. In a class test containing 15 questions, 4 marks are given for every correct answer and (–2) marks are given for every incorrect answer. Daniel attempts all questions but only 9 of her answers are correct. What is her total score? 🔘 24 🔘 56 🔘 -24 🔘  -12 🔘 36
So, marks given for 9 correct answers = 4 × 9 = 36
Marks given for one incorrect answer = – 2
So, marks given for 6 = (15 – 9) incorrect answers = (–2) × 6 = –12
Therefore, Gurpreet’s total score = 36 + ( –12) = 24
 6. Suppose we represent the distance above the ground by a positive integer and that below the ground by a negative integer, then answer the following: 6 (i) An elevator descends into a mine shaft at the rate of 5 meters per minute. What will be its position after one hour? 🔘  50 🔘 150 🔘  200 🔘  250 🔘  300
Answer: E 300 Change in position of the elevator in one minute = – 5 m Position of the elevator after 60 minutes = (–5) × 60 = – 300 m, i.e., 300 m below down from the starting position of the elevator.
 6 (ii) If it beings to descend from 15 m above the ground, what will be its position after 45 minutes? 🔘 60 m 🔘  110 m 🔘 180 m 🔘 210 m 🔘 330 m
Answer:D 210 m Change in position of the elevator in 45 minutes = (–5) × 45 = –225 m, i.e., 225 m
below ground level. So, the final position of the elevator = –225 + 15 = –210 m, i.e., 210 m below ground level.
 8. For any integer a, what is (–1) × a equal to? 🔘 a 🔘 1 🔘 0 🔘 -1 🔘 -a
