Free GMAT Quant Questions: Practice for Consulting Tests

Last Updated on July 10, 2026

By Florian Smeritschnig, former McKinsey Senior Consultant · Updated July 2026

Consulting firms screen most candidates out with a timed numbers test before a human ever reads their case structure, and free, high-quality practice for that screen is hard to find. Free GMAT quant questions fill the gap. The GMAT Focus Edition trains the exact speed and accuracy with numbers and data that the BCG Online Case, Bain’s tests, and the Kearney and L.E.K. screens reward.

Key Takeaways

• Free GMAT quant questions are some of the best free practice for consulting aptitude tests. The skills overlap almost completely: fast mental math, ratios and percentages, and reading data under a timer.
• The GMAT changed. Since 2024 the only version is the GMAT Focus Edition. Quantitative Reasoning is now 21 questions in 45 minutes, geometry is gone, and Data Sufficiency moved to a new Data Insights section.
• Data Insights is the most consulting-like section on the GMAT. Table analysis, graphics interpretation, and data sufficiency mirror the BCG Online Case and the exhibit work in a live case interview.
• Use GMAT questions to build the skill, not to rehearse the format. Consulting screens are case-embedded, chatbot-run, or game-based, so drill the numeracy here and prepare the specific test with a firm guide.
• This page gives you eight practice questions with full worked solutions and the current free sources for more.

What the GMAT quant section actually tests in 2026

The GMAT Quantitative Reasoning section measures how quickly and accurately you solve arithmetic and algebra problems without a calculator. It is one of three sections on the GMAT Focus Edition, alongside Verbal Reasoning and Data Insights, and each section is scored equally.

If you studied an older guide, throw out the format you remember. The classic GMAT retired at the start of 2024, and the GMAT Focus Edition is now the only version. Two changes matter for quant: geometry was removed, and Data Sufficiency moved out of the quant section into the new Data Insights section. Today’s quant section is pure Problem Solving.

That “no calculator, two minutes a question” pressure is the part that matters for consulting. It forces the same mental arithmetic a consulting screen demands.

Why GMAT quant is free practice for consulting aptitude tests

Most consulting firms now run an online test before live interviews, and the numerical ones test the same core skill the GMAT does: clean, fast math under time pressure. That overlap is why GMAT quant questions work as practice fuel, and why there is so much more free GMAT material than free consulting-test material.

When I was at McKinsey, the candidates who struggled with the numbers rarely lacked intelligence. They lacked reps. They had not done enough timed arithmetic to make percentages, ratios, and growth rates automatic, so under pressure they slowed down, second-guessed, and ran out of clock. GMAT quant is a large, free, well-explained bank of exactly those reps.

Here is how the sections map to the screens you are likely to face.

One honest caveat before you start drilling: GMAT questions build the skill, but they do not rehearse the format. A consulting screen might run inside a chatbot, sit inside a business case, or play out as an interactive simulation. Treat GMAT quant as the gym for your numeracy, then learn your specific test with a dedicated guide. StrategyCase covers each format in the consulting assessment tests guide.

Free GMAT quant practice questions with solutions

Work these under a timer, roughly two minutes each, and no calculator. Try each one before you read the solution. I have given several a business flavor on purpose, because that framing is closer to what a consulting screen throws at you.

Question 1: Margins and unit cost

A product sells for $80 at a 25% gross margin. Material costs rise, and at the same $80 price the margin falls to 15%. By approximately what percentage did the unit cost increase?

A. 8% B. 10% C. 13% D. 15% E. 27%

Solution: C. At a 25% margin, cost is 80 × (1 − 0.25) = $60. At a 15% margin, cost is 80 × (1 − 0.15) = $68. The increase is (68 − 60) ÷ 60 = 8 ÷ 60 ≈ 13.3%. Margin-to-cost conversions like this are the single most common calculation in a profitability case.

Question 2: Constant growth rate

A company’s revenue grows from $50 million to $72 million over two years at a constant annual growth rate. Which is closest to that annual rate?

A. 15% B. 18% C. 20% D. 22% E. 44%

Solution: C. 72 ÷ 50 = 1.44, and 1.44 = (1 + r)². The square root of 1.44 is 1.2, so r = 20% per year. Recognizing that 1.44 is 1.2 squared saves you the messy algebra, and spotting clean squares fast is a real time-saver on both the GMAT and a growth case.

Question 3: Weighted average price

A market has two segments: 400 units sold at $30 and 600 units sold at $55. What is the average revenue per unit across the whole market?

A. $42.50 B. $44.00 C. $45.00 D. $47.50 E. $50.00

Solution: C. Total revenue is (400 × 30) + (600 × 55) = 12,000 + 33,000 = $45,000 across 1,000 units, so $45 per unit. Note it is not the simple average of $30 and $55 ($42.50), because the larger segment pulls the average toward $55. Weighted averages trip up more candidates than any other “easy” topic.

Question 4: Inverse proportion

A team of 4 analysts finishes a piece of work in 15 days. Working at the same rate, how many days would 6 analysts take?

A. 8 B. 10 C. 12 D. 18 E. 22.5

Solution: B. The work is 4 × 15 = 60 analyst-days. Divide by 6 analysts to get 10 days. More people means less time, so the relationship is inverse, and setting it up as total work first keeps you from guessing.

Question 5: Break-even volume

Fixed costs are $120,000 per month. A unit sells for $50 and costs $30 to make. How many units must the company sell each month to break even?

A. 2,400 B. 4,000 C. 6,000 D. 8,000 E. 12,000

Solution: C. Contribution per unit is 50 − 30 = $20. Break-even is fixed costs divided by contribution: 120,000 ÷ 20 = 6,000 units. Break-even math shows up in pricing, market entry, and profitability cases, so make this reflexive.

Question 6: Consecutive integers

The sum of five consecutive integers is 285. What is the largest of the five?

A. 55 B. 57 C. 58 D. 59 E. 61

Solution: D. For consecutive integers, the middle value is the average: 285 ÷ 5 = 57. So the five integers are 55, 56, 57, 58, 59, and the largest is 59. Using the average as the middle term is far faster than writing out algebra with x.

Data Insights: the most consulting-like section on the GMAT

Data Insights is the newest GMAT Focus section, and for a consulting applicant it is the most valuable one to practice. It blends five formats, including the Data Sufficiency questions that used to live in the quant section, plus table analysis, graphics interpretation, multi-source reasoning, and two-part analysis.

Why it matters: reading a table, spotting the one number that resolves a question, and synthesizing two data sources is precisely what the BCG Online Case and the exhibit portion of a live case interview demand. If you want to sharpen the exact muscle a case exhibit tests, our data and exhibit interpretation drills go deeper on the consulting side.

Data Sufficiency is worth a special mention because it trains a habit consultants live by: figuring out the minimum information you need before you start calculating. You are not asked to find the answer. You are asked whether the given statements are enough to find it. The five answer choices are always the same:

• A. Statement (1) alone is sufficient, but statement (2) alone is not.
• B. Statement (2) alone is sufficient, but statement (1) alone is not.
• C. Both statements together are sufficient, but neither alone is.
• D. Each statement alone is sufficient.
• E. The two statements together are still not sufficient.

Question 7: Data Sufficiency, profitability

Was Company X profitable last quarter?

(1) Its revenue was $10 million.
(2) Its total costs were $9.2 million.

Solution: C. Statement (1) alone tells you nothing about costs, so it is insufficient. Statement (2) alone tells you nothing about revenue, so it is insufficient. Together, profit is 10 − 9.2 = $0.8 million, which is positive, so the company was profitable. Both statements together are sufficient, but neither alone.

Question 8: Data Sufficiency, units versus price

A retailer’s revenue rose 20% year over year. Did its unit sales increase?

(1) The average price per unit was unchanged.
(2) The retailer sold five different products.

Solution: A. Revenue equals price times units. If the average price per unit did not change, then a 20% revenue rise had to come from a 20% rise in units, so statement (1) is sufficient on its own. Statement (2) tells you nothing about price or volume, so it is useless. Statement (1) alone is sufficient. This “revenue equals price times volume” decomposition is the backbone of nearly every revenue case.

Where to get more free GMAT quant practice

The current article you may have landed on last year listed several prep vendors that have since changed or shut down, so here is a cleaner, current set. Prioritize the official source first.

• GMAT Official Starter Kit (free): from GMAC, the maker of the exam. It includes 70 real practice questions across all three sections and two full-length adaptive practice exams that use the actual scoring algorithm. This is the highest-quality free practice available anywhere.
• mba.com exam content: the official breakdown of every section and question type, so you always work from the current format rather than a retired one.
• GMAT Club: an enormous free forum bank of Problem Solving questions with community explanations, sortable by topic and difficulty. Excellent for high-volume drilling.

A note on the old resource list: Veritas Prep, which the earlier version of this article linked to, discontinued its GMAT service in 2022, so that link is gone. Stick with the official kit and GMAT Club for reliable, free material.

How to practice GMAT quant for a consulting screen

Doing questions is not the same as getting faster. Here is the approach I give coaching clients who are using GMAT material to prepare for a consulting test.

1. Drill without a calculator, always. Every consulting screen and case interview bans one, so build the habit now. If you reach for a calculator on GMAT practice, you are training the wrong reflex.
2. Time every set. Two minutes per Problem Solving question. Speed under pressure is the skill being tested, not whether you can eventually get the right answer.
3. Review your misses ruthlessly. For every wrong answer, write down whether it was a concept gap, a careless slip, or a pacing failure. The pattern tells you what to fix.
4. Convert the skill to the format. Once your arithmetic is fast, move to the actual test. Our case interview math guide and the firm-specific guides in the consulting assessment tests hub rehearse the real formats. Pair this quant work with our free GMAT critical reasoning questions to train the logic side too.

If you would rather follow one structured plan, StrategyCase’s Case Interview Math Mastery turns this raw numeracy into case-ready speed with hundreds of drills, and 1-on-1 coaching with Florian pinpoints exactly where your math is costing you time.
