Let’s review what GMAC says about Problem Solving questions.The Quantitative section tests three broad content areas: All of the rules and concepts from these areas that are tested are generally covered in high school mathematics classes.When working on the quantitative section of the GMAT, keep in mind the following: There are 200 marbles in a box. If there are 40 more red marbles than blue, how many red marbles are there in the box?
Problem-solving questions cover three subject areas: arithmetic, elementary algebra, and geometry. There are 200 marbles in the box, so you have x x 40 = 200, which is equivalent to 2x 40 = 200, or x = 80. Three times a number is the same as the number added to 60.
The number of questions for each of these three subjects is in the neighborhood of When working on a problem-solving question, make sure that you read the question carefully, know exactly what you have to find, solve the problem, and select the best of the answer choices given.
It’s just that doing so may take more time than you really have.
However, there’s often a simpler—and faster—approach that involves little more than some basic math.
Some GMAT questions entice you to use math that is actually more sophisticated than you really need for the GMAT.
It’s not that you can’t solve the questions using sophisticated math.
Questions are selected from a wide array of topics that typically appear in the GMAT test.
Questions in problem solving, data sufficiency and verbal reasoning are posted at regular intervals.
Remember: All numbers in the quantitative section are real numbers, and all figures shown are drawn as accurately as possible, unless stated otherwise.
Straight lines may sometimes appear jagged on the computer screen.
