Sample GRE Practice Math Questions and Answers
To give you a taste of what to expect, here are some sample GRE math questions along with their answers.
Question 1: Arithmetic
If \( x = 15 \) and \( y = 3 \), what is the value of \( \frac{x^2 - y^2}{x + y} \)?
- A) 3
- B) 5
- C) 6
- D) 9
Answer:
Using the difference of squares, \( x^2 - y^2 = (x - y)(x + y) \). Therefore,
\[
\frac{x^2 - y^2}{x + y} = \frac{(x - y)(x + y)}{x + y} = x - y = 15 - 3 = 12.
\]
None of the given options is correct. Always double-check your calculations!
Question 2: Algebra
What is the solution to the equation \( 2x + 3 = 11 \)?
- A) 2
- B) 4
- C) 5
- D) 8
Answer:
Subtract 3 from both sides:
\[
2x = 11 - 3 \implies 2x = 8.
\]
Now, divide by 2:
\[
x = \frac{8}{2} = 4.
\]
The correct answer is B) 4.
Question 3: Geometry
A rectangle has a length of 10 units and a width of 6 units. What is its area?
- A) 30
- B) 60
- C) 70
- D) 80
Answer:
Area \( A \) of a rectangle is given by the formula \( A = \text{length} \times \text{width} \):
\[
A = 10 \times 6 = 60.
\]
The correct answer is B) 60.
Question 4: Data Analysis
A survey of 100 students shows that 40% prefer online classes over traditional classes. How many students prefer online classes?
- A) 30
- B) 40
- C) 50
- D) 60
Answer:
To find the number of students who prefer online classes, calculate 40% of 100:
\[
0.40 \times 100 = 40.
\]
The correct answer is B) 40.
Conclusion
Preparing for the GRE quantitative reasoning section requires a well-rounded approach that includes understanding the types of questions, practicing regularly, and analyzing your performance. Utilize practice math questions and answers to build your skills and confidence. With commitment and the right strategies, you can achieve the score you desire on the GRE. Happy studying!
