The GMAT Data Insights section tests your analytical and reasoning skills with a variety of question types, and one of the most challenging of these is the Two-Part Analysis question. This question type challenges you to think about relationships between variables and solve problems with interconnected parts. The key to mastering it lies in understanding the system that ties both parts together, which is often more complex than it first appears.
Let’s break down what Two-Part Analysis questions are, how to approach them, and some expert strategies that will help you excel.
What Are Two-Part Analysis Questions in GMAT?
In Two-Part Analysis, you’re presented with a problem that requires two related answers, each drawn from the same pool of options. The answer choices are placed in a chart with two columns, and you’re required to select one response from each column. For example, you might be asked to determine how many apples John and Mary each have. The answers for John and Mary come from the same list of options, and the two correct answers must work together to satisfy the conditions of the problem.
The most critical point here is that the two parts are not isolated — the answers interact with each other. So, solving these questions is less about calculating two separate solutions and more about understanding the system or set of relationships connecting them. You’re essentially figuring out how to balance both parts of the question.
For example, if John and Mary together have a total of 20 apples, and you know John has fewer apples than Mary, then only one combination of the two answer choices will work. The challenge lies in quickly
Types of Two-Part Analysis Questions
Two-Part Analysis questions on the GMAT fall into three general categories: quantitative-based, logic-based, and verbal-based. Each type brings its own challenge, but the core principle — solving for two interrelated parts — remains the same.
Quant-Based Questions
Quantitative problems are the most straightforward of the three subtypes, where you’ll need to use mathematical reasoning to find the correct pair of answers. Often, these questions will involve systems of equations, competing rates, or percentage growth problems. The trick here is to understand the relationships between the numerical variables and how solving one part helps you solve the other.

Logic-Based Questions
These questions focus on logical reasoning, asking you to work with a set of conditions or rules to arrive at the correct pair of answers. Think of it like a logic puzzle: if one condition is true, what must also be true for the other condition to hold? Often, this requires a process of elimination and understanding how different scenarios interact.
An example might involve determining who wins gold and silver medals in two different races, given specific conditions about who competed in each race and their respective rankings. These might sound familiar from childhood. “Albert, Betsy, Charlie, and Danielle are in a race. Danielle finishes sometime after Charlie. Albert and Betsy never finish next to one another.”, etc etc You’ll need to piece together the rules and use deductive reasoning to answer both columns correct
Verbal-Based Questions
Verbal-based Two-Part Analysis questions are similar to critical reasoning questions, where you’re asked to evaluate arguments or relationships between statements. These questions test your ability to extract meaning from complex language and apply it to both parts of the problem. Often, you’ll need to analyze the logic behind the argument to figure out how the two parts interact, and answer accordingly.
Quant Topics That Appear in Two-Part Analysis Questions
When it comes to quant-based Two-Part Analysis questions, several math topics commonly appear:
- Systems of Equations: You’ll often encounter problems where two variables are related, and solving one equation helps you solve the other.
- Rate Problems: These problems typically involve calculating how two entities working together (or at different rates) contribute to a total outcome.
- Percentage Growth: Another common topic, where you’re asked to calculate how two percentages or rates of change impact a final result
.
Understanding these core quant concepts is essential for handling the more number-heavy Two-Part Analysis questions.
The Best Strategy for Tackling Two-Part Analysis Questions
When tackling Two-Part Analysis questions, the goal is to think systematically rather than linearly. Here’s a simple strategy to help you approach these problems efficiently:
1. Understand the Problem as a System
The first step is to recognize that you’re dealing with a system where both parts of the question are interconnected. Break down the relationships and understand how one part affects the other. For example, if you know John and Mary need to share a specific number of apples, work out how their individual totals must add up to that fixed value.
2. Dissect the Variables
Isolate the key variables. Ask yourself, what are the conditions that both answers must satisfy? This step helps you filter out irrelevant data and focus on the important pieces of information.
3. Link the Two Parts
Identify how the two parts of the question are linked. Is it through a shared equation, logical relationship, or some other condition? This is the crucial step, where you shift from thinking about each part individually to understanding how they work together.
4. Solve Systematically
Once you’ve mapped out the relationships, solve for one part of the question, and use that solution to help solve for the other part. If necessary, use a process of elimination to rule out options that don’t meet the conditions of the problem.
