### The GRE Math section is divided into 3 types:

• GRE Math - Quantitative Comparisons
• GRE Math - Problem Solving
• GRE Math - Data Interpretation

### GRE Math - Quantitative Comparisons, for example:

Question: Runner A and runner B start running from the same spot. The first runs south at a rate of 3 kilometers per hour and the second runs west at a rate of 4 kilometers per hour.

 Column A: Distance from runner A to Runner B after 9 hours of running at a constant rate Column B: 45 kilometers
• a. The quantity in Column A is greater
• b. The quantity in Column B is greater
• c. The two quantities are equal
• d. The relationship cannot be determined from the informatioin given

### GRE Math - Problem Solving, for example:

Question: A certain machine drills 30 holes in 8 minutes. At that constant rate, how many holes will 4 such machines drill in 1 1/3 hours?

• a. 300
• b. 900
• c. 960
• d. 1,200
• e. 2,560

### GRE Math - Data Interpretation, for example: The top and bottom of each bar indicate, respectively, the highest and lowest daily number of shirts sold during the month. The heavy line across each bar indicates the average (arithmetic mean) number of shirts sold per day during the month.

Questions: What was the range in the daily number of shirts sold during March?

• a. 20
• b. 45
• c. 50
• d. 60
