Understanding the question types in any exam will help you to crack the test in a better manner. In this section let us know the question types of Quantitative Reasoning in GRE. The Quantitative reasoning sections have four types of questions:
Let us know more about each of the question types in detail.
Quantitative Comparison Questions
In this question type, you are asked to compare two quantities A and B and select one of the four answer choices.
Answer choices are fixed and are always in the same order as given below:
a) Quantity A is greater
b) Quantity B is greater
c) The quantities are equal
d) The relationship cannot be determined from the information givenLet us solve a couple of examples to know more.
Let us solve a couple of examples to know more.
In this question, we are asked to compare the values of ‘f’ and ‘h’. Since the Quantities have variables it is better to assign a value and compare.
Suppose we say h=6 and g=2 then f = 3.
Now that the Quantity B is greater, can it be considered that B is the answer? No!
We should actually eliminate answer choices A and C.
Let us assign another set of values to the variables to confirm our answer. Say h=3 and g=1, then f=3. Since both the Quantities have now become equal, answer choice B gets eliminated. Hence D is the correct answer as the relationship cannot be determined.
This question is asking to compare the two expressions which involve one variable. Though assigning values to the variable is a good idea, let’s try expanding the expression and understand it better.
Quantity A can be rewritten as
Now we can actually compare and say Quantity A is always greater than Quantity B.
Multiple Choice Questions- Select One Answer Choice
In this question type, you are asked to solve the problem and pick one answer among the five answer choices.Here are few examples.
What is the area of the square base of a cube that has a volume of 64?
If the cost of 1 hat and 2 scarves is $23 and the cost of 2 hats and 1 scarf is $19, then what is the cost of one hat and one scarf?
Let the cost of one hat be $H and the cost of one scarf be $S.
Let us write the given information in the form of equations.
H + 2S = 23 ——- (1)
2H + S = 19 ——- (2)
We need to solve for H + S and not the individual costs.
Adding both the equations we get
3H + 3S = 42
Dividing both the sides of the above equation by 3 we get
H + S = 14.
Hence C is the correct answer.
