Answer 2

1. Answer: (a) move to the right

Explanation: When we add positive integers, we move to the right on the number line. For example, to add +2 and +4 we move 4 steps to the right of +2. Thus, +2 +4 = +6.

2. Answer: (b) move to the left

Explanation: Add a negative integer, we move to the left. subtract a positive integer, we move to the left. Subtracting a negative integer, we move to the right.

3. Answer: (a) move to the right

Explanation: Add a positive integer, we move to the right. add a negative integer, we move to the left. subtract a positive integer, we move to the left. Subtracting a negative integer, we move to the right.

4. Answer: (d) Both p and q are false

Explanation: When we add a positive integer and negative integer then it is not necessary that the result would be a negative integer. It can be a positive integer also. For eg- (+8)+(−6)=2. Hence the p statement is false. When we add two negative integers, we will always get a negative integer. For eg- (−7)+(−9)=−16. Hence q statement is also false.

5. Answer: (b) (- 8) + (- 4) < (- 8) – (- 4)

Explanation: (-8) + (-4) = -12

(-8) – (-4) = -4

Hence (- 8) + (- 4) < (- 8) – (- 4)

6. Answer: (b) 50 and 30

Explanation:Let the two numbers be x and y. 

It is given that three times one number is equal to five times the other that is: 

3x=5y

3x−5y=0..........(1) 

Also, the sum of the numbers is 80 that is: 

x+y=80..........(2).

Multiply the equation 2 by 3:

3x+3y=240..........(3)
  
Now subtract equation 1 from equation 3 to eliminate x, because the coefficients of x are the same. So, we get

(3x−3x)+(3y+5y)=240−0

i.e. 8y=240

i.e. y=30

Substituting this value of y in (1), we get

3x−150=0

i.e. 3x=150

i.e. x=50

Hence, the two numbers are 50 and 30.

7. Answer: (b) 16

Explanation: Given, 40% of [100−20% of 300]

\(=\frac{40}{100}\times[100-\frac{20}{100}\times300]\)

\(=\frac{40}{100}[100-60]\)

= 16.

8. Answer: (b) 1

Explanation:((2)⁰+(3)⁰+(5)⁰)⁰

= (1 +1 +1)⁰

= 3⁰

= 1

9. Answer: (а) 0

Explanation: (−10)×0×(−15) 

0 multiplied with anything gives 0.

Hence (−10)×0×(−15)=0

10. Answer: (b) 1

Explanation:−1

=−1×1.

11. Answer: (d) 5

Explanation:x/5 =1

Multiply both sides by 5 we get

\(\frac{x}{5}\times5=1\times5\)

x=5

∴x=5

12. Answer: (c) 0

Explanation: An identity element that in a given mathematical system leaves unchanged any element to which it is added.  We know that any number added to 0 is still the same number and hence the system doesn’t change for any integer we will have a+0=a=0+a ⟹0 is an additive identity. Thus, the additive identity for integers is 0.

13. Answer: (a) 1

Explanation: The multiplicative identity of any integer a  is a number b which when multiplied with a, leaves it unchanged, i.e. b is called as the multiplicative identity of any integer a if a× b = a. Now, when we multiply 1 with any of the integers we get a × 1 = a = 1 × a.So, 1 is the multiplicative identity for integers.

14. Answer: (c) Distributive property

Explanation: Distributive property says that multiplication and division can be distributed over parenthesis. a x (b+c) = a x b + a x c

15. Answer: (c) Rs 1000

Explanation: 2000 – 1000 

= Rs 1000

16. Answer: (a) – 32

Explanation: The product of 2 numbers of opposite signs is negative.

17. Answer: (c) -10

Explanation: If a is an integer then (- a) is its additive inverse.

18. Answer: (b) (a + b) + c

Explanation: addition of an integer is associative.

19. Answer: (a) -10

Explanation: Division of 2 numbers of opposite signs is negative.

20. Answer: (b) 0

Explanation: Zero divided by any non-zero integer, the result is zero.

21. Answer: (d) – 4

Explanation: The predecessor of an integer is just before it on the number line.

22. Answer: (d) 12

Explanation: The successor of an integer is right to it on a number line.

23. Answer: (c) 5 is greater than 3

Explanation: Greater number is on the right of smaller on a number line.

24. Answer: (b) –

Explanation: The product of 3 negative integers is a negative integer.

25. Answer: (b) <

Explanation:because (-9) + (-4) = -13

= and (-9) – (-4) = (-9) + 4 

= -5 – 13 < – 5
