Quantitative Section – GMAT Data Sufficiency Problems

GMAT Data Sufficiency Questions

The GMAT Data Sufficiency questions interspersed throughout the Quantitative section are a unique type of question in the GMAT. The questions contain mathematical equations that might involve algebra or geometry much like the more straightforward Problem Solving questions in this section.

What is unique about Data Sufficiency questions is that the test taker does not have to solve the actual equations. Instead, each equation will be followed by two statements containing data pertaining to the equation. The question will then ask, in order to solve the equation, is the first statement alone sufficient? Is the second statement alone sufficient? Are the two statements both required for solving the equation, but neither sufficient on its own? Is either statement sufficient on its own? Is neither sufficient on its own?

In other words, test takers need only discern what information is required to solve the equation. Often, that can be done without actually solving the equation. In fact, if test takers can determine what data is required for solving the equation without actually solving it, valuable time can be saved. Every Data Sufficiency problem follows the same format, with the five multiple choices listed above.
