15 Top GMAT questions and answers

15 sample GMAT questions and answers spanning Quantitative, Data Sufficiency, Verbal,
Critical Reasoning, and Integrated Reasoning. These examples reflect the types of challenges
you might encounter on test day.



1. Quantitative Problem Solving: Linear Equation

Question:
Solve for x:
3x – 5 = 16
Answer:
Add 5 to both sides: 3x = 21, so x = 7.



2. Quantitative Problem Solving: Quadratic Equation

Question:
If (x – 4)(x + 2) = 0, what is the sum of the possible values of x?
Answer:
The solutions are x = 4 and x = –2. Their sum is 4 + (–2) = 2.



3. Quantitative Problem Solving: Geometry

Question:
A rectangle’s length is twice its width. If the perimeter is 36, what is the area of the rectangle?
Answer:
Let width = w and length = 2w. The perimeter is 2(w + 2w) = 6w = 36, so w = 6 and length = 12.
Area = 6 × 12 = 72.



4. Quantitative Problem Solving: Percent Increase

Question:
A quantity increases from 50 to 65. What is the percent increase?
Answer:
Increase = 65 – 50 = 15.
Percent increase = (15/50) × 100 = 30%.



5. Quantitative Problem Solving: Ratio
