Hard GRE Table Questions Practice Questions

Concept Explanation

Hard GRE Table Questions are advanced data interpretation tasks that require candidates to synthesize, compare, and calculate specific values from complex datasets presented in a tabular format. Unlike simpler data interpretation questions, hard-level table problems often involve multi-step calculations, such as finding the percent change between two derived values or identifying trends across multiple categories simultaneously. These questions test your quantitative reasoning and your ability to filter out irrelevant information under time pressure. Success on these items requires a firm grasp of GRE practice questions with explanations that focus on arithmetic, percentages, and ratios. You must be able to quickly sort data mentally or use the on-screen calculator's memory functions to handle large numbers. According to the ETS Quantitative Reasoning overview, data interpretation accounts for a significant portion of the math section, making table proficiency essential for a high score.

Solved Examples

Review these worked examples to understand the logic required for high-difficulty table analysis.

1. Example 1: Percent of a Percent
   Suppose a table shows that Company X has 500 employees. 40% are in the Sales department, and of those in Sales, 25% have an MBA. How many Sales employees do not have an MBA?
   1. Find the total number of Sales employees: $500 \times 0.40 = 200$.
   2. Find the percentage of Sales employees without an MBA: $100\% - 25\% = 75\%$.
   3. Calculate the final number: $200 \times 0.75 = 150$.
   4. The answer is 150.
2. Example 2: Weighted Averages
   A table lists three classes: Class A (20 students, average score 80), Class B (30 students, average score 90), and Class C (50 students, average score 70). What is the average score for all students combined?
   1. Calculate the total points for each class: $20 \times 80 = 1,600$; $30 \times 90 = 2,700$; $50 \times 70 = 3,500$.
   2. Sum the total points: $1,600 + 2,700 + 3,500 = 7,800$.
   3. Sum the total number of students: $20 + 30 + 50 = 100$.
   4. Divide total points by total students: $\frac{7,800}{100} = 78$.
   5. The answer is 78.
3. Example 3: Comparative Growth Rates
   In 2010, Country A's GDP was $200 billion and Country B's was $300 billion. In 2020, Country A's GDP grew by 50% and Country B's grew by 20%. What is the difference in their GDPs in 2020?
   1. Calculate Country A in 2020: $200 \times 1.50 = 300$ billion.
   2. Calculate Country B in 2020: $300 \times 1.20 = 360$ billion.
   3. Find the difference: $360 - 300 = 60$ billion.
   4. The answer is $60 billion.

Practice Questions

Use the following table for questions 1–4:

Region	Total Revenue ($ Millions)	Operating Costs ($ Millions)	Market Share (%)
North America	450	310	35%
Europe	320	240	25%
Asia-Pacific	580	400	30%
Other	150	120	10%

1. Which region has the highest profit margin (Profit divided by Revenue)?
2. If the total market size is $5 billion, how much revenue did the "Other" region generate relative to its market share?
3. What is the ratio of the profit in the Asia-Pacific region to the profit in the Europe region?

4. If Operating Costs in Europe increase by 15% next year while Revenue stays the same, what will be the new profit for that region?
5. (New Data) A library has 12,000 books. 60% are fiction. Of the non-fiction books, 20% are biographies. How many books are neither fiction nor biographies?
6. A car dealership sold 150 cars in June. 40% were SUVs, and 20% of SUVs were hybrid. How many non-hybrid SUVs were sold?
7. If a company's revenue increased from $2.4 million to $3.6 million over 5 years, what was the total percentage increase?
8. In a survey of 800 people, 45% preferred Brand A. If 25% of those who preferred Brand A were over 60 years old, how many people who preferred Brand A were 60 or younger?

Answers & Explanations

1. North America. Profit = Revenue - Costs. North America: $450 - 310 = 140$; Margin: $\frac{140}{450} \approx 0.311$. Europe: $320 - 240 = 80$; Margin: $\frac{80}{320} = 0.25$. Asia-Pacific: $580 - 400 = 180$; Margin: $\frac{180}{580} \approx 0.310$. Other: $150 - 120 = 30$; Margin: $\frac{30}{150} = 0.20$. North America is the highest.
2. $150 Million. The question asks for the revenue the "Other" region actually generated according to the table, which is explicitly listed as $150 million. Note: $5 billion is the total market, and 10% of that is $500 million, but the table shows the company's specific revenue.
3. 9:4. Profit Asia-Pacific = $580 - 400 = 180$. Profit Europe = $320 - 240 = 80$. Ratio = $\frac{180}{80} = \frac{18}{8} = \frac{9}{4}$.
4. $44 Million. Current Costs = $240M. Increase = $240 \times 0.15 = 36$. New Costs = $240 + 36 = 276$. New Profit = $320 - 276 = 44$.
5. 3,840. Non-fiction = $12,000 \times 0.40 = 4,800$. Non-biography non-fiction = $4,800 \times 0.80 = 3,840$.
6. 48. SUVs = $150 \times 0.40 = 60$. Non-hybrid SUVs = $60 \times 0.80 = 48$.
7. 50%. Increase = $3.6 - 2.4 = 1.2$. Percentage = $\frac{1.2}{2.4} \times 100 = 50\%$. For more practice on these types of calculations, check out our Adaptive GRE Practice Test.
8. 270. Brand A total = $800 \times 0.45 = 360$. 60 or younger = $360 \times 0.75 = 270$.

1. If a table shows a value increased from 50 to 80, what is the percentage increase?

• A30%
• B37.5%
• C60%
• D160%

Frequently Asked Questions

How do I handle tables with missing data on the GRE?

You must use the provided relationships, such as totals or percentages of other columns, to calculate the missing values. Often, the question itself provides the necessary context to derive the missing piece through subtraction or algebraic manipulation.

Can I use the calculator for Hard GRE Table Questions?

Yes, the on-screen calculator is available and highly recommended for multi-step arithmetic involving large numbers or decimals. However, you should still look for opportunities to simplify fractions or estimate before typing to save time.

What is the most common trap in table questions?

The most common trap is misreading the units, such as confusing "thousands" with "millions." Always double-check the table headers and footnotes for scale indicators to ensure your final decimal placement is correct.

How much time should I spend on a single table set?

Typically, a set of 3-4 questions based on one table should take about 5-7 minutes. If a single question requires more than two minutes of calculation, it may be better to flag it and return later after completing easier items.

Are these questions more about math or logic?

Hard GRE table questions are a hybrid of both. While the math is usually basic arithmetic or percentages, the logic required to identify which specific data points to use from a dense table is what makes the questions difficult.
