A comprehensive introduction to the quantitative reasoning skills tested on the GMAT, covering arithmetic, algebra, geometry, and data analysis.
Word Problems and Translating Scenarios
Making Math out of Words
Word problems test your ability to convert everyday scenarios into mathematical models. The GMAT loves to present information in stories, so practicing translation is crucial.
Key Steps
- Read the problem carefully and identify what's being asked.
- Assign variables to unknowns.
- Write equations that represent the relationships.
- Solve and interpret your answer in context.
Common Traps
- Missing hidden relationships or extra information
- Mixing up units
Pro-Tip
Draw a quick table or diagram to organize information, especially with rates and mixtures.
Real-World Power
Translating word problems helps with budgeting, planning travel, or comparing deals.
Examples
A train travels 60 miles in 1.5 hours. What is its average speed? Speed = Distance ÷ Time = 60 ÷ 1.5 = 40 mph.
If you buy 3 apples and 2 oranges for $5, and each apple costs $1, how much does each orange cost? 3×1 + 2×O = 5 ⇒ 2O = 2 ⇒ O = $1.
In a Nutshell
Transforming wordy scenarios into solvable math problems is a key GMAT skill.
