GMAT Two Part Analysis

Two-Part Analysis questions present a brief written scenario or problem and ask you to make two choices related to that information. These choices are connected to each other in some way; for example, they might be two steps involved in solving a problem or two components required to successfully complete a task.

In Two-Part Analysis questions you may be asked to, for example,

  • Calculate the proportions of two different components in a mixture
  • Determine something that would be lost and something that would be gained in a trade-off
  • Find the maximum number of two different products that could be purchased within a certain budget
  • Identify a first action and a second action that together would bring a company into compliance with a new rule

The possible answers and your choices will be given in a table format. The possible answers are listed in the third column, on the right side of the table. Your choices for the first part and second part of the question will be recorded in the first and second columns of the table, respectively. Remember that you need to make a choice for each of the first two vertical columns of the table, not one for each horizontal row.


A set of expressions consists of a total of four expressions: these three expressions {2n+8, n+4, 6n–2} and one additional expression. From the following expressions, select the one that could be the fourth expression in the set and the one that could be the resulting arithmetic mean of the four expressions in the set. Make only one selection per column.

Approach this question by trying out the possible answer choices as potential fourth expressions to see which, when it’s included with other expressions in the set, results in an arithmetic mean that’s another of the possible answer choices.

First, evaluate the three provided expressions. All contain one-digit values that are multiplied by n and then have a one-digit value added or subtracted from that term. So evaluate similar expressions, such as Choices (B), (C), and (F) before you consider less similar expressions, such as Choices (A), (D), and (E).
