The last calculation is wrong because the ones revised “ only once” and “twice” are two completely separate categories-there is no overlap. In this example, the key is to carefully note that the question says, “40 were revised only once.” The “sucker” incorrect answer on this question is calculated as follows:ġ0 x $3 = $30 (incorrectly assuming that you have accounted for the first charge of $3 in the first revision category) When you are performing well on this exam, there is something hard about every question, so always try to identify where that difficulty is coming from. It is amazing how many smart, high-scoring students miss it! There is no hard math present and you just need to follow specific instructions, but people are far too casual on these types of “reading comprehension” math questions.

This problem has been circulating in the official practice tests for over a decade. Take a look at the following questions, and check out our problem solving video below. However, it is just as important to read carefully, leverage every hint, and choose the right strategy (backsolving, number picking, conceptual thinking, etc.) People think of multiple-choice problem solving questions as just plain math questions, but this GMAT sample question shows that they are much more than that. To succeed on these questions, you obviously need the requisite knowledge related to the content area being tested-math skills related to arithmetic, algebra, etc. The multiple choice “problem solving” questions, one of the two types of GMAT math questions, are the most familiar, yet students generally do not approach them properly. In the explanations below, I will use some of the core tenets of the Menlo Coaching GMAT curriculum to breakdown two official GMAT problem solving questions and provide important principles for correctly attacking this question type in the future. But even if you come up with the correct answer to an official problem, you still might not understand the underlying principles used to create that particular question, leaving yourself open to traps and pitfalls set by the test writers. We’ve already covered why studying with official practice questions is the best way to prepare for the GMAT. GMAT Prep Course Memorial Day Flash Sale - Enroll Before May 30 and save $320!
