GMAT Graphics Interpretation : (GI) Questions

A certain developer offers both paid and free versions of a certain mobile tablet application on four different tablet models. For each of Models A–D, the graph shows the percent of tablets that have the paid version and the percent of devices that have the free version.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.

Table 1: Text Analysis
Text Component | Literal Content | Simple Interpretation |
---|---|---|
Subject | A certain developer offers both paid and free versions of a certain mobile tablet application | A single developer provides one app in both paid and free forms |
Tablet Models | On four different tablet models | The app is released on exactly four tablet types (A, B, C, D) |
Data Representation | The graph shows the percent of tablets that have the paid version and ... the free version | For each tablet model, we have separate percentages for paid and for free installs |
Table 2: Chart Analysis
Chart Component | What's Shown | What This Tells Us |
---|---|---|
Chart Type | Grouped vertical bar chart | Paid and free version rates are compared side by side for models |
X-axis | Models A, B, C, D | Each tablet model is individually represented |
Y-axis | 0% to 70% scale | Percentages of device installations for each version |
Bar Coding | Solid blue = paid; diagonal stripes = free | Bars are visually distinct and easy to compare within a model |
Key Patterns | Model D: bars nearly equal (11% paid, 9% free) | Nearly identical rates of paid and free versions for Model D |
Model C: 5% paid vs 51% free | Strong user preference for free over paid version on Model C |
Key Insights
Model D has the smallest difference between paid (11%) and free (9%) app usage (only 2 percentage points). In contrast, Model C shows the largest difference, with only 5% on paid but 51% on free (a 46 point difference). The bar chart makes these contrasts visually obvious. Paid adoption dominates on Model B, while Model C's users overwhelmingly choose the free version. These trends are clear both numerically and visually, making it easy to see which models have similar versus sharply different rates for each app version.
Step-by-Step Solution
Question 1: Finding the Model with the Least Difference between Paid and Free Versions
Complete Statement:
Among Models A–D, the model with the least difference between the percent of tablets that have the paid version of the application and the percent of tablets that have the free version was Model ______.
Breaking Down the Statement
- Statement Breakdown 1:
- Key Phrase: least difference
- Meaning: We are looking for the smallest gap between two numbers.
- Relation to Chart: We must compare the paid vs. free percentages for each model and find the pair with the closest values.
- Important Implications: It's not about the absolute values, but about how close the two values are to each other for each model.
- Statement Breakdown 2:
- Key Phrase: percent of tablets that have the paid version... and the percent of tablets that have the free version
- Meaning: These are the two bars we need to compare for each model.
- Relation to Chart: For each model (A-D), compare the heights of the 'paid' and 'free' bars.
- Important Implications: We compare only within each model, not across different models.
- What is needed: Which model (A, B, C, or D) has paid and free percentages that are closest together.
Solution:
- Condensed Solution Implementation:
Look at each model's bars and visually judge which pair is closest together. - Necessary Data points:
Model A: paid 25%, free 8%; Model B: paid 61%, free 39%; Model C: paid 5%, free 51%; Model D: paid 11%, free 9%. - Calculations Estimations:
Calculate or estimate the differences: A: 17%, B: 22%, C: 46%, D: 2%. - Comparison to Answer Choices:
Model D has the smallest difference (2%). All others have larger differences.
FINAL ANSWER Blank 1: D
Question 2: Finding the Model with the Greatest Difference between Paid and Free Versions
Complete Statement:
Among Models A–D, the model with the greatest difference between the percent of tablets that have the paid version of the application and the percent of tablets that have the free version was Model ______.
Breaking Down the Statement
- Statement Breakdown 1:
- Key Phrase: greatest difference
- Meaning: We are looking for the biggest gap between two numbers.
- Relation to Chart: We must compare the paid vs. free percentages for each model and find the pair with the largest difference.
- Statement Breakdown 2:
- Key Phrase: percent of tablets that have the paid version... and the percent of tablets that have the free version
- Meaning: Again, these are the two bars for each model we are comparing.
- Relation to Chart: For each model (A-D), find out where the bars are the furthest apart.
- What is needed: Which model (A, B, C, or D) has the largest difference between its paid and free percentages.
Solution:
- Condensed Solution Implementation:
Check each model's bars and see which pair has the most noticeable gap. - Necessary Data points:
Model A: difference 17%, Model B: difference 22%, Model C: difference 46%, Model D: difference 2%. - Calculations Estimations:
Calculate the size of the gap for each: C's gap (46%) is clearly the largest. - Comparison to Answer Choices:
Model C has the largest difference by far, compared to the other models.
FINAL ANSWER Blank 2: C
Summary
By visually comparing the paid and free values on the chart for each model, Model D has the smallest difference and Model C has the largest. No complex calculations are needed; estimation by inspection is sufficient.
Question Independence Analysis
Each question asks about a different extreme (least and greatest difference), and can be answered separately. The answers are independent of each other.
