GMAT Exam: A Simple Guide To Solving Word Problems - The Problem-Solving Process

Here is a general process for problem solving on the GMAT.
 

1. Understand the problem. Ask yourself: What content area (arithmetic, algebra, or geometry) is the question’s primary focus? Is the problem a familiar type (for example, a mixture problem)? Determine what you need to find. Look for words like find, determine, what is, how many, how far, how much, and the like. Decide how many unknowns are in the problem.
 

2. Make a plan. Decide how you should go about determining a solution. Identify the information in the problem. Is there a formula that you need? If measurement units are given, determine what units the answer should have. Decide whether making a chart or sketching a diagram would be helpful. Try to relate the current problem to practice problems you have worked out. Make sure your plan will result in a solution that answers the question.
 

3. Carry out the plan. Using the plan you decided upon, work out the solution on the erasable noteboard provided at the testing center. Make sure you copy all information accurately. Write neatly so that you can check over your work. If the answer should have units, check whether your calculations will result in the proper units for the answer.

Tip: If you are using an equation to find the solution, you might find it convenient to omit the units while solving the equation, given that you have already checked that the answer will have the proper units.

4. Look back. Verbalize your answer. Did you answer the question that was asked? Check your solution in the context of the problem. Does it make sense? Is it reasonable? Are units needed?
