Question 1
1 / -0

Which of the following statements is CORRECT?

(A) All integers are whole numbers and all natural numbers are integers.
(B) All whole numbers are integers and all integers are natural numbers.
(C) All natural numbers are whole numbers and all whole numbers are integers.
(D) All integers are whole numbers and all integers are natural numbers.

A
A

B
B

C
C

D
D

Solution

All natural numbers such as 1,2,3,4 etc are whole numbers and all whole numbers such as 0,1,2,3,4 are integers (which include negative numbers also).
Question 2
1 / -0

The value of X in - 20 × (4 + (-2)) = -20 × 4 + (-20) × X, is

A
2

B
-19

C
6

D
-2

Solution

We have,
(-20) × (4 + (-2)) = -20 × 4 + (-20) × X
(-20) × (4 - 2) = -20 × 4 + (-20) × X
(-20) × (2) = - 20 × 4 + (-20) × X
-40 = -80 - 20X
40 = -20X
X = -2
Question 3
1 / -0

What will be the sign of the product if we together multiply 198 negative integers and 9 positive integers?

A
Negative

B
Positive

C
Cannot say

D
Insufficient data

Solution

Product of odd numbers of negative integers is always negative and product of even numbers of negative integers is always positive.

(Product of 198 negative integers) × (Product of 9 positive integers)

= Positive × Positive

= Positive
Question 4
1 / -0

Which pair of numbers does not have a product equal to 72?

A
(-8,-9)

B
(-6,-12)

C
(8, -9)

D
(6,12)

Solution

1. (-8) × (-9) = 72
2. (-6) × (-12) = 72
3. (8) × (-9) = -72
4. (6) × (12) = 72
Question 5
1 / -0

Which of the following lists of integers is in descending order?

A
6, 1, -6, 12, 4

B
6, 12, -6, 4, 1

C
12, 6, 1, -4, -6

D
-6, -4, 1, 6, 12

Solution

12 is the largest and -6 is the smallest integer.
Question 6
1 / -0

Find the value of the given expression.

(-62) - (21) + 36 - 25 - (-102) + 31+ (-21)

A
-40

B
35

C
40

D
42

Solution

(-62) - (21) + 36 - 25 - (-102) + 31 + (-21)
= -62 - 21 + 36 - 25 + 102 + 31 - 21
= -129 + 169 = 40
Question 7
1 / -0

The absolute value of -25 + 16 + 31 - 53 is

A
-125

B
-31

C
31

D
125

Solution

Absolute value means the non-negative value of a number.
I-25 + 16 + 31 - 53I
= I-78 + 47I
= I- 31I
= 31
Question 8
1 / -0

If m and n are integers such that m ≠ n, then which of the following is CORRECT?

A
2(m - n) = 2(n - m).

B
m + n + 7 = m + n + 6.

C
5(m + n) = 5(n + m).

D
6(m - n) = 6(n - m).

Solution

Since m + n = n + m;
5(m + n) = 5(n + m).
