What Is Word problems on the GMAT?
Word problems on the GMAT are quant questions wrapped in real-world scenarios, testing your ability to translate prose into math. They appear throughout the Quantitative section, so mastering them is key to a competitive score.
Definition
Word problems are GMAT Quant questions that present mathematical concepts through a narrative or real-life situation. Instead of giving you an equation to solve directly, they describe a scenario—like a train traveling, a store discount, or a mixture of liquids—and ask you to find an unknown value. Your first task is to convert the words into algebraic expressions, equations, or inequalities.
Why it matters on the GMAT
Word problems are not a separate question type; they are the format for many Problem Solving and Data Sufficiency questions. They test your reading comprehension, logical reasoning, and ability to model situations mathematically. Because they require an extra step of translation, they often take more time and are a common source of errors. Mastering them directly impacts your Quant score and your time management.
A concrete example
Scenario: “A store sells a shirt for $30 after a 25% discount. What was the original price?”
Translation: Let p be the original price. The discount means you pay 75% of p, so 0.75p = 30. Solving gives p = 40.
This simple example shows the core skill: identifying the unknown, setting up an equation, and solving.
Common mistakes
- Misreading the scenario: Overlooking keywords like “after,” “before,” “increase,” or “decrease” leads to wrong equations.
- Forgetting to define variables: Jumping into calculations without clearly labeling what each variable represents causes confusion.
- Ignoring units: Mixing units (e.g., minutes vs. hours) is a frequent error in rate and work problems.
- Rushing the translation: Trying to do it all in your head often leads to arithmetic slips. Write down the equation.
How to practice it
Practice by reading a word problem and, before solving, write down the variables and the equation. Use official GMAT questions to get used to the phrasing. Categorize problems (e.g., work/rate, mixtures, percentages) and practice each type. Time yourself to improve speed, but focus on accuracy in translation first. Review every mistake to see where your translation broke down.
