The quantitative reasoning measure has four types of questions:
- Quantitative Comparison questions
- Multiple-choice questions-Select One Answer Choice
- Multiple-choice questions-Select One or More Answer Choices
- Numeric Entry questions
Each question appears either independently as a discrete question or as part of a set of questions called a Data Interpretation set. All of the questions in a Data Interpretation set are based on the same data presented in tables, graphs, or other displays of data.
In the computer-delivered test, you are allowed to use a basic calculator-provided on-screen-on the Quantitative Reasoning measure. Information about using the calculator appears later in this chapter.
Quantitative Comparison Questions
Questions of this type ask you to compare two quantities-Quantity A and Quantity B- and then determine which of the following statements describes the comparison.
- Quantity A is greater.
- Quantity B is greater.
- The two quantities are equal.
- The relationship cannot be determined from the information given.
Quantity A Quantity B
The least prime number greater than 24 2) The greatest prime number less than 28.
a) Quantity A is greater
b) Quantity B is greater
c) The two quantities are equal
d) The relationship cannot be determined from the information given.
Ans) For the integers greater than 24, note that 25, 26, 27 and 28 are not prime numbers, but 29 is a prime number, as are 31 and many other great integers. Thus, 29 is the least prime number greater than 24, and Quantity A is 29.
For the integers, less than 28, note that 27, 26, 25 and 24 are not prime numbers, but 23 is a prime number, as are 19 and several other lesser integers. Thus 23 is the greatest prime number less than 28, and Quantity B is 23.
Therefore, Quantity A is greater. (a) is correct.
Multiple-Choice Questions –Select One Answer Choice
These questions are multiple-choice questions that ask you to select only one answer choice from a list of five choices.
Select a single answer choice.
Q 1) If 5x + 32 = 4 – 2x, what is the value of x?
Ans) Solving the equation for x, you get 7x = -28, and so x = -4.
The correct answer is Choice A, -4
Multiple-Choice Questions –Select One or More Answer Choice
These questions are multiple-choice questions that ask you to select one or more answer choices. A question may or may not specify the number of choices to select. These questions are marked with square boxes beside the answer choices, not circles or ovals.
Select one or more answer choice.
Q 1) Which of the following integers are multiple of both 2 and 3?
Ans) We can easily identify multiple of 2 and multiple of 3. Here, multiple of 2 are 8, 12, 18 and 36. Multiple of 3 are 9, 12, 18, 21 and 36. Therefore, 12, 18 and 36 are multiples of both 2 and 3.
Alternatively, if you realize that every number that is a multiple of 2 and 3 is also a multiple of 6. You can identify the choices that are multiple of 6.
The correct answer consists of Choices C (12), D (18) and F (36).
Numeric Entry Questions
Questions of this type ask you either to enter your answer as an integer or decimal in a single answer box or to enter it as a fraction in two separate boxes- one for the numerator and one for the denominator. In the computer-delivered test, use the computer mouse and keyboard to enter your answer.
Q1) One pen costs $0.25 and one marker costs $0.35. At those prices, what is the total cost of 18 pens and 100 markers?
Ans) Cost of one pen = $0.25
Cost of one marker = $0.35
Cost of 18 pens = 0.25 x 18 = $4.5
Cost of 100 markers = 0.35 x 100 = $35
Total cost of 18 pens and 100 markers = $39.5
