The skill
What is a numerical reasoning test?
A numerical reasoning test presents figures in a workplace context — a table of regional sales, a chart of monthly costs, a short financial extract, or a dashboard spread across several tabs — and asks you to decide what those figures support. You are given the data. Your job is to locate the part that matters, choose one calculation, and answer before the clock moves you on.
It is not a mathematics exam. The operations are the ones you met at school: percentages, ratios, rates, averages and simple currency conversion. What makes the test difficult is performing them accurately, from unfamiliar data, at a pace someone else set.
The response format is not fixed either. Some assessments want a number. Aon's numerical assessment instead gives you statements to mark true, false or cannot say, and Pearson's NDIT includes free-response items rather than only multiple choice.
If your assessment is a run of sums with no chart, table or business context, it is a calculation test rather than a numerical reasoning test. SHL, Aon and Pearson all publish both kinds separately, and they reward different preparation. The calculation guide is linked at the end of this page.

Six original questions covering the formats above, hardest habits first. Commit to an answer before opening the solution — the solution shows the method and names why every wrong option is on the list.
A support team reports its first-contact resolution rate for two quarters, alongside the number of tickets handled.
Q1: 4,200 tickets, resolution rate 62% · Q2: 5,100 tickets, resolution rate 68%
By what percentage did the resolution rate increase from Q1 to Q2?
Show the worked solution
Answer: C — 9.7%.
- The question asks for a percentage increase in the rate, not the change measured in percentage points.
- The rate moved 68 − 62 = 6 percentage points.
- Percentage increase is the change over the original: 6 ÷ 62 = 0.0967, which is 9.7%.
- The ticket counts are not needed. They are included as distractors and are not used in the calculation.
Why the other options are there. Option A is the percentage-point change read as a percentage, which is the value you land on if you subtract the two percentages and stop. Option B divides by the new figure instead of the original. Option D is the growth in ticket volume, which answers a question nobody asked.
A retailer reports Q3 results for three markets. Revenue and costs are stated in local currency, with the sterling rate given for each market.
Germany: revenue €1,860,000, costs €1,320,000, £1 = €1.20 · Sweden: revenue kr17,400,000, costs kr12,500,000, £1 = kr13.00 · Poland: revenue zł7,300,000, costs zł4,900,000, £1 = zł5.00
Which market produced the highest profit in sterling?
Show the worked solution
Answer: C — Poland.
- Take profit in local currency first: Germany €540,000, Sweden kr4,900,000, Poland zł2,400,000.
- Convert each one separately, because the rates differ: €540,000 ÷ 1.20 = £450,000.
- kr4,900,000 ÷ 13 = about £377,000, and zł2,400,000 ÷ 5 = £480,000.
- Poland is highest at £480,000, ahead of Germany at £450,000.
Why the other options are there. Sweden shows by far the largest local-currency figure and converts to the smallest sterling profit. Comparing numbers that sit in different units loses the mark before any arithmetic starts, and it is why the exchange row exists.
A laptop is sold in a promotion at 15% below its original list price.
Promotional price: £646
What was the original list price?
Show the worked solution
Answer: C — £760.00.
- The £646 is what remains AFTER the reduction, so it is 85% of the original, not 100%.
- Original price = discounted price ÷ (1 − 0.15) = 646 ÷ 0.85.
- 646 ÷ 0.85 = £760.
- Check by running the discount forward: 760 × 0.85 = 646, which matches the promotional price.
Why the other options are there. Option B adds 15% of the sale price back on, which answers a different question — a discount is taken from the original price, not from the sale price. Option A applies the 15% reduction a second time. Option D is a plausible round figure, and 780 × 0.85 gives £663, not £646.
A department's £45,000 budget is divided between marketing, product and operations.
Split ratio — marketing : product : operations = 4 : 3 : 2
How much more does marketing receive than operations?
Show the worked solution
Answer: B — £10,000.
- Total the ratio parts first: 4 + 3 + 2 = 9 parts.
- One part is £45,000 ÷ 9 = £5,000.
- Marketing holds 4 parts (£20,000) and operations holds 2 parts (£10,000).
- The difference is 2 parts: £20,000 − £10,000 = £10,000.
Why the other options are there. Option D is marketing's whole share, which answers 'how much does marketing receive'. Option C is product's share, a number you compute on the way. Option A is one ratio part — the difference asked for is two parts, because marketing and operations sit two parts apart.
A plant runs two production lines simultaneously through a shift.
Line A: 1,200 units in 8 hours · Line B: 900 units in 5 hours
While both lines are running, what is their combined output per hour?
Show the worked solution
Answer: C — 330 units.
- Convert each line to a rate before combining anything: Line A is 1,200 ÷ 8 = 150 units per hour.
- Line B is 900 ÷ 5 = 180 units per hour.
- Rates for lines running at the same time add: 150 + 180 = 330 units per hour.
- Estimate check: two lines each producing 150 to 180 an hour must land above 300, which eliminates half the options at a glance.
Why the other options are there. Option B pools the units and divides by the longer shift, 2,100 ÷ 8, treating both lines as if they ran 8 hours. Option A is the average of the two rates, which answers 'per line', not 'combined'. Totals can never be divided by a time that only one of the lines actually worked.
This is the response format Aon's scales numerical uses: a claim about the data, not a number. A report on last year states only the following.
“Online sales rose 22% in 2025, while store sales fell 8%.”
Consider the statement: “Total revenue rose in 2025.” True, false, or cannot say?
Show the worked solution
Answer: C — Cannot say.
- A statement is only TRUE if the data forces it in every scenario consistent with what is given, and only FALSE if the data rules it out in every scenario.
- Percentage changes cannot be combined without the sizes they apply to, and the report gives no revenue figures.
- Construct one consistent case each way. If online was £10m and stores £0.1m, total rises. If online was £0.1m and stores £10m, the 8% store fall outweighs the online gain and total falls.
- Both outcomes fit the data, so the data cannot decide the statement: cannot say.
Why the other options are there. True feels supported because the rise, 22%, is bigger than the fall, 8% — but a percentage is not an amount, and a small channel growing fast can be outweighed by a large channel shrinking slowly. Choosing false makes the same mistake in reverse. Cannot say is a measurement of the data's limits, not a guess.

What employers are looking at
What do numerical reasoning tests measure?
Employers use numerical reasoning to predict how well someone will work with the figures a role actually produces: budget variance, conversion rates, headcount ratios, pricing and forecast accuracy. Pearson describes its own numerical test as assessing the interpretation and manipulation of the numerical data routinely encountered in the workplace.
Three abilities are being separated. Data selection: can you find the one row that matters in a dense table. Method choice: can you turn a question into a single calculation instead of three. Judgement: can you tell that an answer of 940% is wrong before you commit to it.
Reading your result
How numerical reasoning tests are scored
Your raw score is rarely what the employer sees. Providers convert it into a comparison against other people, which changes what a good result means and what is worth optimising for.
- Results are percentiles, not marks out of ten. Criteria sends employers a raw score alongside a percentile, and Korn Ferry compares your result with a reference group of similar candidates. A 70th-percentile result means you beat 70% of the comparison group, whatever the raw count was.
- No provider publishes a pass mark. Korn Ferry states directly that it does not set one; any benchmark belongs to the hiring organisation. If a recruiter has disclosed a target, that is the only target worth working to.
- The norm group shapes the number. The same raw performance scores differently against graduate applicants than against the general population. This is why comparing scores across different assessments, or across friends' tests, says very little.
- Unanswered questions are part of the design. Aon tells candidates they are not expected to answer every task, and Criteria reports that fewer than 1% of candidates complete all 50 CCAT questions. Accuracy at a sustainable pace usually beats rushed completion.
- On an adaptive test, difficulty is not feedback. SHL's Verify Interactive and Korn Ferry's Elements select the next question from your last answer, so a harder question often follows a correct one. You cannot read your score from how hard the test feels.
Question formats
What do the questions look like?
The material and the response format both vary by provider. Learn the mechanics first and add the interface last.
- Table and chart interpretation. A data set followed by a question needing one or two values from it. The work is finding the right two numbers before any arithmetic starts.
- Percentages and percentage change. Increase, decrease, reverse percentages, and the difference between a percentage change and a percentage-point change.
- Ratios, proportions and shares. Splitting a total, comparing two shares, or scaling a known ratio up to a new total.
- Rates, averages and per-unit figures. Cost per unit, output per hour, weighted averages, and the mean of a subset rather than the whole table.
- Currency and simple financial arithmetic. Converting before comparing, applying a margin, or working with a figure that is already net of something.
- Statement evaluation. Rather than a number, you judge whether a statement about the data is true, false or cannot be determined. Aon's scales numerical uses exactly this response set.
- Sufficiency questions. You decide whether the information supplied is enough to answer at all. Pearson's RANRA includes a dedicated sufficiency section.
A table shows four regions with quarterly revenue in local currency, a cost column, and an exchange-rate row underneath. The question asks which region improved its profit margin the most between Q1 and Q2. Nothing in it is hard on its own. Getting it right means noticing that the rates differ by region, that margin is not the same as profit, and that only two of the four rows are worth calculating.
Launch coverage
Which providers use numerical reasoning tests?
The underlying maths is portable. The interface, the response format and the clock are not. Match the name in your invitation to the route below.
- Verify Interactive Numerical Reasoning. SHL's product fact sheet lists 18 minutes and a maximum of 10 questions in an interactive, activity-based, adaptive format. SHL Direct describes the classic task as answering from figures presented in statistical tables.
- scales numerical. Multiple data sheets and a series of statements, each marked TRUE, FALSE or CANNOT SAY. Aon lists the module at 12 minutes and 37 tasks, and tells candidates to have a pen, paper and calculator to hand.
- Talent Q Elements Numerical. Adaptive delivery with a 16-minute limit. Korn Ferry tells candidates to have a calculator, paper and pen, and recommends a desktop or laptop because the drop-down answer controls behave poorly on tablets.
- Numerical Data Interpretation Test. 21 items in 30 timed minutes. Pearson permits a calculator and includes free-response items alongside multiple choice.
- Numerical Analysis. Usually met inside a Swift battery. Saville lists Swift Analysis Aptitude at 18 to 24 minutes across verbal, numerical, diagrammatic and abstract reasoning, and Swift Executive Aptitude at 18 minutes.
- Logiks Numerical (Advanced). Talogy publishes the Logiks range at 12 to 25 minutes and 20 to 50 items depending on version, either as a combined general test or as one focused ability.
- CCAT. Numerical items sit inside one mixed test: 50 questions in 15 minutes, no calculator permitted, with verbal and spatial questions interleaved.

What varies, and what does not
Timing and calculator rules
There is no single numerical reasoning test, so there is no single time limit, calculator rule or pass mark. These are the figures the providers themselves publish.
- Time limits and question volumes vary widely. Pearson's NDIT runs 30 minutes for 21 items. Criteria's CCAT gives 15 minutes for 50 mixed questions. Aon lists scales numerical at 12 minutes for 37 tasks.
- Calculator policy is per assessment, never universal. Aon and Korn Ferry both tell candidates to have a calculator ready, and Pearson permits one on the NDIT. Criteria states plainly that no calculators are allowed on the CCAT. Your own instructions are the authority.
- Finishing is not always expected. Aon tells candidates they are not expected to answer every question. Criteria reports that fewer than 1% of candidates complete all 50 CCAT questions. Unanswered items are designed into some of these tests.
- Adaptive delivery changes what a hard question means. SHL's Verify Interactive numerical assessment and Korn Ferry's Elements tests both select the next item from your last answer. An adaptive test may follow a correct answer with a harder item, but you cannot read your score from how hard the questions feel, so treat difficulty as normal behaviour rather than as feedback.
A repeatable approach
A method that survives the clock
The same five moves work whether the data is a table, a chart or a dashboard. Practise them until they are automatic, then add the clock.
- 1
Read the question before the data. Know what you are looking for and you will scan the table once instead of three times. Read the data first and you will read all of it.
- 2
Name the calculation before you start it. Say what you are about to compute — change over original — before touching a number. Most wrong answers are the right arithmetic on the wrong expression.
- 3
Check units, period and label. Thousands or millions, quarter or year, gross or net, this region or the total. A misread label produces correct arithmetic on the wrong quantity, so the answer survives a sanity check on the working.
- 4
Estimate, then compute. A rough answer tells you which options are impossible and catches a decimal-place slip immediately. On a no-calculator test it is often the whole method.
- 5
Decide your abandon point before you start. Set a fixed ceiling per question. When you reach it, choose the best remaining option and move. One rescued question is never worth three lost ones.
What slows progress
Common mistakes, and the fix for each
- Calculating before checking the label. Fix: read the axis title, the units row and the period column before the first keystroke. A calculation run against the wrong units or the wrong period is wrong however accurate the arithmetic, and nothing later in the question reveals it.
- Confusing percentage change with percentage points. Fix: whenever a figure is already a percentage, decide which of the two the question wants, and write the base you are dividing by next to your working.
- Reading the whole table. Fix: locate only the cells the question names. Dense tables are padded deliberately, and most of the data in a question is not needed for that question.
- Rescuing one hard question. Fix: set an abandon point before you start and honour it. On a test where fewer than 1% of candidates finish, protecting pace matters more than any single item.
- Practising with the wrong calculator rule. Fix: find out whether your assessment permits one before you build a habit. Mental estimation and calculator-first working are genuinely different skills.

How do you solve percentage questions under time pressure?
Write the base before the arithmetic. Every percentage question turns on one decision — what is this a percentage OF — and most wrong options on real tests are the right arithmetic on the wrong base. Change over original for percentage change; the reduced figure over one-minus-the-rate for reverse percentages; never add a discount back onto a sale price.
Keep percentage points and percent apart. When the data is already in percentages, a rise from 62% to 68% is 6 percentage points but a 9.7% increase — sample question 1 above turns entirely on that distinction, and so do real items in SHL-style and Aon-style sets.
Then make the fraction equivalents automatic: 12.5% is an eighth, 33⅓% a third, 16⅔% a sixth. On calculator-free tests like the CCAT they replace the calculator; on the rest they are the estimate that catches a slipped decimal.
In practice
How do you read a data table quickly without missing the trap?
Read the question first, and let it name the cells you need. A dense table is padded deliberately — sample question 1 carries ticket volumes that no correct calculation touches — and candidates who read data before question read most of it twice.
Then spend three seconds on the frame before any value: units row, period columns, and whether figures are gross or net, thousands or millions. A misread label produces clean arithmetic on the wrong quantity, which is the one error a checking pass will not catch, because the working looks right.
Finally, compute only what the comparison needs. Asked which region improved most, a glance at direction often eliminates half the rows before any division, and on a 15-minute test those seconds are the score.
In practice
How do you avoid unit and currency conversion errors?
Convert before you compare, never after. Figures in different currencies, or different magnitudes, cannot be ranked as they stand — sample question 2's largest local-currency number converts to the smallest sterling profit, and the exchange-rate row exists precisely to punish skipping it.
Anchor the direction of every rate before dividing. Write it as a sentence — one pound buys 13 kronor, so kronor become pounds by dividing by 13 — and the upside-down conversion, which multiplies instead, becomes impossible to commit silently.
Sanity-check magnitude at the end: a Swedish quarterly profit of £63 million from a kr4.9 million base fails the glance test. Order-of-magnitude checks catch conversion errors faster than redoing the arithmetic.
A clear route
How to prepare in the days you have
Most candidates get a few days of notice, not a study term. This order gets the most out of a short run-up.
- 1
First, fix the arithmetic rather than the data. Drill percentages, reverse percentages, ratios and averages untimed until the method is automatic. If this is where you lose marks, no amount of chart practice will help.
- 2
Next, one calculation per question. Work untimed on tables and charts, writing the expression before computing it. Review each miss by cause: data selection, method, arithmetic or pace.
- 3
Then add the provider's format. Switch to the response format named in your invitation — numeric entry, drop-downs, or true, false and cannot say — and to the calculator rule that comes with it.
- 4
Time it. Short timed sets first, then a full-length rehearsal at the real pace with the real interaction.
- 5
On the last day, repair rather than cram. Re-solve only the questions you got wrong, and stop. New material the night before adds noise, not skill.
Cognivy uses your assessment date to choose the route rather than asking you to predict a study schedule. When you sit down to practise, you choose the session length that fits that day.
Pace
Getting faster without losing accuracy
Speed on a numerical test comes from removing work, not from working faster. Four things remove the most.
- Estimate first, always. An approximation is enough to reject options that are an order of magnitude out, and it tells you whether a full calculation is needed at all.
- Learn the fraction equivalents. 12.5% is an eighth, 33⅓% is a third, 16⅔% is a sixth. Recognising them turns a calculator step into a mental one, which matters most where no calculator is allowed.
- Keep one working layout. Write the same way every time: expression, numbers, answer, units. A consistent layout is what lets you catch your own slip without redoing the question.
- Rehearse the interaction, not only the maths. Drop-downs, tabbed data sheets and free-response boxes each cost seconds until they are familiar. Korn Ferry specifically warns that Elements Numerical drop-downs render badly on tablets.

Numerical reasoning test FAQs
It depends entirely on the assessment. SHL's fact sheet gives Verify Interactive Numerical Reasoning 18 minutes for up to 10 questions. Pearson's NDIT is 21 items in 30 minutes. Aon lists scales numerical at 12 minutes for 37 tasks. Criteria's CCAT gives 15 minutes for 50 mixed questions. Use the time stated in your own invitation.
Sometimes, and it is never safe to assume. Aon and Korn Ferry both tell candidates to have a calculator to hand for their numerical assessments, and Pearson permits one on the NDIT. Criteria states that no calculators are allowed on the CCAT. The instructions attached to your assessment decide it.
There is no universal figure. Results are normally reported as a percentile against a comparison group, and the benchmark belongs to the employer. Korn Ferry says explicitly that it does not set pass marks. Ask the recruiter whether a target has been disclosed.
Percentages, ratios, averages, rates, simple currency conversion, and reading a chart or table accurately. No algebra beyond rearranging a simple expression. The difficulty is pace and data selection, not mathematical level.
A numerical reasoning test gives you context — a chart, a table, a report extract — and asks what follows from it. A calculation test gives you the operation directly and measures how quickly and accurately you execute it. SHL, Aon and Pearson all publish both kinds under separate product names.
Not always. Aon tells candidates they are not expected to complete every task, and Criteria reports that fewer than 1% of candidates answer all 50 CCAT questions. Work for accuracy at a sustainable pace rather than for completion.
Some are. SHL's Verify Interactive numerical assessment uses computer-adaptive delivery, and Korn Ferry states that all of its cognitive ability tests are adaptive. An adaptive test may follow a correct answer with a harder item, but you cannot read your score from how hard the questions feel, so treat rising difficulty as normal behaviour rather than as feedback.
