GMAT Quantitative Reasoning Skills - Problem-solving

The quantitative section of the GMAT consists of two primary types of questions, which includes problem-solving questions and data-sufficiency questions. The problem-solving questions on the exam are designed to evaluate an individual's ability to solve mathematical problems related to basic arithmetic, algebra, and geometry. Most of the problem-solving questions found on the exam specifically examine the individual's knowledge of addition, subtraction, multiplication, division, how to find the area of a geometric figure, averages, how to find the circumference of a circle, estimations, exponents, fractions, mathematical comparisons, rounding, solving for missing variables in an algebraic equation, solving word problems, square roots, and a variety of other similar topics. Each of these questions will present the individual with either a word problem or equation that the individual must solve and the individual must choose the correct solution to the problem or equation from the options available. For example, these questions may present the individual with simple equations such as "140 + 60 + 250" that the individual must determine the sum of the three numbers, simple word problems such as "if it takes 1 gallon of gas to go 25 miles, how many will it take to go 150 miles?", a geometric figure that the individual must find the area for, and other similar types of problems. The exam-taker will usually be presented with approximately 22 to 24 of these multiple-choice problem-solving questions on the exam.
