180 Multiple-Choice Questions with Answers and Rationales
SECTION 1: BASIC NUMERACY & NUMBER SYSTEMS (Questions 1-25)
1. Which number system includes zero, negative numbers, and positive numbers?
A) Whole numbers
B) Natural numbers
C) Integers
D) Rational numbers
Correct Answer: C
Rationale: Integers include all positive and negative whole numbers, including
zero. Natural numbers are positive only (1, 2, 3...), and whole numbers are non-
negative (0, 1, 2, 3...). Integers are a subset of rational numbers .
2. A rational number can be defined as:
,A) Any number that can be placed on a number line
B) A number that can be expressed as a ratio of two integers (fraction)
C) Any non-negative number
D) A number that cannot be expressed as a fraction
Correct Answer: B
Rationale: Rational numbers can be written as a/b where a and b are integers and
b ≠ 0. This includes terminating and repeating decimals. All integers are rational
numbers .
3. Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square
roots of the whole number?
A) ± 2.3
B) ± 3.3
C) ± 4
D) ± 5
,Correct Answer: D
Rationale: The whole number in the set is 25. The square roots of 25 are ±5
because 5 × 5 = 25 and (-5) × (-5) = 25 .
4. A whole number is defined as:
A) Any number including negatives
B) A number whose value is 0 or greater and can be represented without a
fractional or decimal component
C) Any number that can be expressed as a fraction
D) Any number that can be placed on a number line
Correct Answer: B
Rationale: Whole numbers are non-negative integers: 0, 1, 2, 3, etc. They do not
include fractions, decimals, or negative numbers .
5. Which property states that adding 0 to any number does not change its value?
, A) Commutative property
B) Associative property
C) Identity property of addition
D) Distributive property
Correct Answer: C
Rationale: The identity property of addition states that a + 0 = a for any real
number a. The identity property of multiplication states a × 1 = a .
6. Which of the following is NOT a real number?
A) 0
B) ½
C) √2
D) √(-1)
Correct Answer: D
