Prepare for SHL Numerical Reasoning with Worked Examples, Test Versions, Formula Strategy and Timed Practice

The SHL Numerical Reasoning Test is a psychometric assessment and one of the most common numerical aptitude tests used in recruitment and graduate assessment processes around the world. It measures how well you can understand numerical data, read tables and charts, perform calculations, compare figures and make accurate decisions under time pressure.

The test is not about advanced mathematics. Most questions use practical maths: percentages, ratios, averages, differences, currency conversion, profit, cost, growth and data interpretation.

The difficult part is that the information is usually presented in tables, graphs or business scenarios, and the answer options are often close. Many candidates do not fail because they cannot calculate. They fail because they use the wrong row, the wrong base value, the wrong unit or the wrong interpretation of the question.

At ReasoningCampus.com, we prepare candidates for SHL-style numerical reasoning with structured practice, full worked explanations, formula guidance, question-type classification, timed exercises and a clear solving method.

SHL Direct describes numerical reasoning questions as questions answered using facts and figures presented in statistical tables.

Best for: SHL Numerical Reasoning, SHL Verify G+, graduate assessments, internship tests, finance tests, consulting assessments, engineering tests, business analyst assessments and international pre-employment aptitude tests.

Preparation Method

ReasoningCampus Method

Start Practising SHL Numerical Reasoning Test Practice

To prepare properly for SHL numerical reasoning, you need more than random maths questions.

You need to practise:

  • table interpretation,
  • chart interpretation,
  • percentage change,
  • ratios and proportions,
  • averages and weighted averages,
  • currency conversions,
  • profit, cost and revenue questions,
  • growth rates,
  • multi-step calculations,
  • data sufficiency,
  • calculator discipline,
  • time management,
  • answer elimination.

ReasoningCampus focuses on the way candidates actually need to think in the test.

You learn:

  • what the question is really asking,
  • which data matters,
  • which calculation is needed,
  • which answer options are traps,
  • why the correct answer is correct,
  • why the wrong answers are tempting.

What Is the SHL Numerical Reasoning Test?

The SHL Numerical Reasoning Test evaluates your ability to interpret numerical data and answer questions based on that data.

You may be shown:

  • sales tables,
  • revenue charts,
  • cost reports,
  • line graphs,
  • pie charts,
  • exchange-rate tables,
  • employee data,
  • productivity data,
  • financial summaries,
  • market-share data.

You then choose the correct answer from several options.

Typical questions ask you to calculate:

  • a percentage increase,
  • a percentage decrease,
  • a total,
  • a difference,
  • a ratio,
  • an average,
  • a weighted average,
  • a currency conversion,
  • a profit margin,
  • a trend,
  • the most accurate conclusion.

The test is designed to measure practical numerical judgment, not classroom maths.

Who Takes SHL Numerical Reasoning Tests?

SHL-style numerical reasoning tests are commonly used in recruitment for roles where candidates must interpret data quickly and accurately.

They are often used for:

  • graduate schemes,
  • internships,
  • finance roles,
  • consulting roles,
  • analyst roles,
  • engineering roles,
  • operations roles,
  • management trainee programmes,
  • sales and commercial roles,
  • public sector recruitment,
  • international corporate hiring.

Candidates in the UK, USA, Canada, Australia, India, Singapore, UAE, Europe and other international markets may encounter SHL-style numerical reasoning as part of an online assessment.

The exact test you receive depends on the employer, the role and the assessment platform.

Is the SHL Numerical Reasoning Test Hard?

Yes, it can be hard.

Not because the maths is impossible, but because the test combines several pressures at once:

  • strict timing,
  • dense tables,
  • close answer options,
  • irrelevant data,
  • hidden units,
  • confusing chart scales,
  • multi-step calculations,
  • percentage traps,
  • calculator errors,
  • no time to overthink.

A strong candidate is not only someone who can calculate. A strong candidate can identify the correct calculation quickly and avoid the trap answer.

SHL Numerical Test Versions

Your SHL numerical test may appear in different formats. Always check the instructions in your own assessment invitation.

The main SHL-style numerical formats are:

Test FormatWhat It Usually Looks LikeMain Challenge
SHL Numerical InteractiveActivity-based numerical tasks with interactive elementsUnderstanding the interface and the calculation
SHL Numerical Multiple-ChoiceTables, graphs and answer optionsFast data reading and accurate calculation
SHL Verify G+ NumericalNumerical reasoning as part of a general ability testSwitching between numerical, deductive and inductive reasoning
Legacy-style SHL NumericalOlder table-and-chart numerical formatClassic data interpretation under time pressure

SHL’s Verify G+ factsheet describes the assessment as measuring Numerical, Deductive and Inductive ability, with 30 questions in total and 10 questions for each ability area.

SHL Numerical Reasoning Interactive Test

The interactive numerical test can feel more difficult than a standard multiple-choice test because you must understand the task format before solving the calculation.

You may need to:

  • interact with a chart,
  • select or adjust data,
  • move values,
  • complete an on-screen numerical task,
  • interpret a changing graph,
  • follow activity-based instructions.

The extra difficulty is not only numerical. It is also procedural.

You must ask two questions:

  1. What does the screen want me to do?
  2. What numerical relationship must I calculate?

This is why practising only standard maths questions is not enough.

SHL Numerical Reasoning Multiple-Choice Test

The multiple-choice version usually gives you a table, graph or chart and asks you to choose the correct answer.

This format may look simple, but it often includes distractors.

A distractor is a wrong answer that looks correct because it is based on a common mistake.

For example, a distractor may come from:

  • using the wrong year,
  • using the wrong row,
  • calculating the absolute difference instead of the percentage change,
  • dividing by the new value instead of the original value,
  • ignoring a refund or discount,
  • confusing revenue with profit,
  • rounding too early.

This is why full explanations matter. You need to understand not only the correct calculation but also the logic behind the wrong options.

SHL Verify G+ Numerical Reasoning

In SHL Verify G+, numerical reasoning may appear together with deductive and inductive reasoning.

This makes the assessment harder because each question type requires a different thinking mode.

Numerical reasoning requires calculation and data interpretation.
Deductive reasoning requires applying rules.
Inductive reasoning requires identifying patterns.

If your invitation mentions Verify G+, General Ability, interactive assessment or activity-based test, read the instructions carefully before beginning.

How Do I Know Which SHL Numerical Test I Have?

Your invitation may not always clearly tell you which version you will take.

Before the test begins, look carefully at the instruction screen.

Check:

  • the test name,
  • number of questions,
  • total time,
  • calculator instructions,
  • whether the test is interactive,
  • whether it says “click on the answer”,
  • whether it mentions dragging or adjusting elements,
  • whether the test is part of a wider general ability assessment.

Do not rush through the instructions. They can tell you how the test behaves.

Can You Use a Calculator?

In SHL numerical or calculation tests, SHL support says candidates may use a calculator unless instructed otherwise. It also notes that candidates may find it useful to have paper and pencil available.

Always follow your own test instructions.

A calculator is useful only if you know what to calculate. Many wrong answers come from correct calculator use applied to the wrong data.

Before your test, practise:

  • percentage calculations,
  • decimal conversions,
  • currency conversions,
  • quick checking,
  • writing intermediate results clearly.

Can You Skip Questions or Go Back?

In some SHL assessment contexts, you may not be able to return to previous questions after submitting an answer because later question difficulty can depend on earlier answers. SHL support explains that the difficulty level of each question may be determined by answers to previous questions.

This changes your strategy.

You must balance accuracy with timing. Spending too long on one difficult question may damage your performance on the rest of the test.

How Is the SHL Numerical Reasoning Test Scored?

SHL numerical scores are usually interpreted in relation to a comparison group. This means your performance may be compared with other candidates in a relevant group, such as graduates, professionals or candidates for similar roles.

There is no single universal pass mark for every SHL numerical test.

The score required can vary depending on:

  • employer,
  • role,
  • candidate pool,
  • test version,
  • assessment stage,
  • comparison group.

Your preparation goal should be to become accurate, fast and consistent across unfamiliar numerical questions.

Can You Find the Real SHL Numerical Test Answers Online?

No reliable preparation provider can give you the real live answers to your actual SHL numerical test.

Be careful with websites or files claiming to contain “real SHL answers”.

The ethical and effective way to prepare is to learn the underlying numerical reasoning skills, so you can solve new questions independently.

ReasoningCampus provides independent SHL-style practice. It does not provide official live SHL questions and is not affiliated with SHL.

Complete SHL Numerical Question Taxonomy

SHL-style numerical reasoning questions can be organised into clear categories. Learning these categories helps you recognise the question type faster.

Financial StatementsRevenue, cost, marginMixing gross and net figures
EstimationApproximate answer selectionOvercalculating under time pressure

How SHL-Style Numerical Questions Are Designed

A well-designed numerical reasoning question does not test only arithmetic. It tests whether you can choose the correct interpretation.

The question designer usually controls four things:

  1. The data source
    A table, chart, graph or mixed display.
  2. The target calculation
    Percentage, ratio, average, comparison, conversion or conclusion.
  3. The distractors
    Wrong answers based on common candidate errors.
  4. The time pressure
    The question must be solvable, but not comfortable.

Why the Answer Options Are So Close

Answer options are often close because the test is trying to separate careful reasoning from rushed calculation.

A wrong answer may be produced by:

  • using the wrong denominator,
  • using the wrong year,
  • calculating difference instead of percentage difference,
  • ignoring a second step,
  • rounding too early,
  • using the wrong exchange rate,
  • choosing the highest number instead of the highest growth.

If your answer matches an option, that does not automatically mean it is correct. You must check whether your calculation matches the exact wording of the question.

The ReasoningCampus Numerical Method

At ReasoningCampus, we teach a six-step method for SHL-style numerical questions.

Read → Locate → Calculate → Check → Eliminate → Answer

Step 1: Read

Read the question before studying all the data.

Ask:

  • What exactly is being asked?
  • Is it asking for a number, percentage, ratio or conclusion?
  • Is it asking for the highest, lowest, closest or greatest change?
  • Is it asking what can or cannot be concluded?

Step 2: Locate

Find only the data you need.

Check:

  • row,
  • column,
  • year,
  • month,
  • unit,
  • currency,
  • axis,
  • legend,
  • footnote.

Step 3: Calculate

Use the shortest reliable calculation.

Sometimes exact calculation is necessary. Sometimes estimation is enough.

Step 4: Check

Before selecting an answer, check:

  • Did I use the right base value?
  • Did I use the correct year?
  • Did I compare like with like?
  • Did I round too early?
  • Did I answer the actual question?
  • Did I confuse percentage with percentage points?

Step 5: Eliminate

Remove answers that cannot be right.

Elimination is especially useful when time is tight.

Step 6: Answer

Choose the answer that matches the data, the calculation and the wording of the question.

Numerical Reasoning Decision Tree

Use this decision tree when you do not know where to start.

Question asks for change

Is it absolute or percentage?

If percentage, identify the original value

Calculate change ÷ original × 100

Check answer options

Question asks for share

Find part

Find total

Calculate part ÷ total × 100

Check whether the period or category is combined

Question asks for highest performance

Do not choose the highest raw number immediately

Check whether performance means margin, rate, growth or efficiency

Calculate the correct measure

Compare all options

Question asks for conclusion

Do not calculate randomly

Identify which answer is supported by the data

Reject answers that add assumptions

Mathematical Foundations for SHL Numerical Reasoning

Percentages

A percentage expresses a value out of 100.

Common percentage calculations:

Question TypeFormula
Find percentage of a numberNumber × Percentage
Find percentage sharePart ÷ Total × 100
Find percentage increaseIncrease ÷ Original × 100
Find percentage decreaseDecrease ÷ Original × 100

Example:

Sales rise from 80 to 100.

Increase = 20
Percentage increase = 20 ÷ 80 × 100 = 25%

Sales fall from 100 to 80.

Decrease = 20
Percentage decrease = 20 ÷ 100 × 100 = 20%

The absolute change is the same, but the percentage change is different because the base is different.

Reverse Percentages

Reverse percentage questions ask you to find the original value.

Example:

A value after a 20% increase is 120.

Original × 1.20 = 120
Original = 120 ÷ 1.20 = 100

Common trap:

Candidates multiply by 0.80 or subtract 20% from 120. That does not reverse the original calculation correctly.

Ratios

A ratio compares quantities.

Example:

The ratio of male to female applicants is 3:2.
Total applicants = 250.

Total parts = 3 + 2 = 5
One part = 250 ÷ 5 = 50
Male applicants = 3 × 50 = 150
Female applicants = 2 × 50 = 100

Common trap:

Reversing the ratio or treating the numbers as percentages.

Proportions

A proportion compares part to whole.

Example:

If 45 out of 180 candidates pass:

45 ÷ 180 × 100 = 25%

Common trap:

Using the wrong total.

Averages

Average = Total ÷ Number of items

Example:

Monthly sales are 40, 50 and 60.

Average = 150 ÷ 3 = 50

Weighted Averages

A weighted average is used when groups have different sizes.

Example:

Group A: 100 candidates, average score 70
Group B: 50 candidates, average score 80

Weighted average:

(100 × 70 + 50 × 80) ÷ 150
= (7,000 + 4,000) ÷ 150
= 11,000 ÷ 150
= 73.3

Common trap:

Averaging 70 and 80 directly gives 75, which is wrong because the groups are not the same size.

Profit, Cost and Revenue

Profit = Revenue − Cost

Profit margin = Profit ÷ Revenue × 100

Example:

Revenue = 200
Cost = 150
Profit = 50
Profit margin = 50 ÷ 200 × 100 = 25%

Common trap:

Dividing profit by cost instead of revenue.

Currency Conversion

Always check how the exchange rate is written.

If 1 USD = 0.80 GBP, then:

USD to GBP: multiply by 0.80
GBP to USD: divide by 0.80

Common trap:

Using the rate in the wrong direction.

CAGR and Compound Growth

CAGR means compound annual growth rate.

It is used when growth happens over multiple periods.

Basic formula:

CAGR = (Final ÷ Initial)^(1 ÷ number of years) − 1

Example:

Revenue grows from 100 to 121 over 2 years.

CAGR = (121 ÷ 100)^(1/2) − 1
= 1.21^0.5 − 1
= 1.10 − 1
= 10%

Common trap:

Taking total growth of 21% and dividing by 2 to get 10.5%. That is simple average growth, not compound annual growth.

Mean, Median and Mode

Mean = arithmetic average.
Median = middle value when data is ordered.
Mode = most frequent value.

Example:

Scores: 40, 50, 50, 70, 90

Mean = 300 ÷ 5 = 60
Median = 50
Mode = 50

Common trap:

Using the mean when the question asks for the median.

Probability

Probability = Favourable outcomes ÷ Total possible outcomes

Example:

If 12 out of 60 applicants are selected:

12 ÷ 60 = 0.20 = 20%

Probability questions are less common than percentages and tables, but the logic can appear in business or selection scenarios.

Estimation

Estimation helps when answer options are far apart.

Example:

If you need 19.8% of 502, estimate:

20% of 500 = 100

If answer options are 50, 100, 150 and 200, estimation is enough.

If answer options are 98, 100, 102 and 104, exact calculation is needed.

Worked Examples: Easy Level

Example 1: Simple Percentage Increase

A company’s monthly sales increased from £80,000 to £92,000.

Question:
What was the percentage increase?

A. 12%
B. 13%
C. 15%
D. 18%

Solution

Increase = 92,000 − 80,000 = 12,000

Percentage increase = 12,000 ÷ 80,000 × 100

= 15%

Correct answer: C. 15%

Why This Is Tricky

The answer 12% is tempting because the increase is £12,000. But the question asks for percentage increase, not the absolute increase.

Example 2: Simple Ratio

A department has 180 employees. The ratio of permanent to temporary employees is 7:2.

Question:
How many employees are temporary?

A. 20
B. 40
C. 60
D. 70

Solution

Total ratio parts = 7 + 2 = 9

One part = 180 ÷ 9 = 20

Temporary employees = 2 parts

2 × 20 = 40

Correct answer: B. 40

Why This Is Tricky

Some candidates divide by 7 instead of 9. The total must be divided by the total number of ratio parts.

Worked Examples: Medium Level

Example 3: Percentage Change with Close Answers

A company reports quarterly revenue.

ProductQ1 RevenueQ2 Revenue
Alpha£48.0m£55.2m
Beta£36.0m£42.3m
Gamma£52.0m£58.5m
Delta£44.0m£50.6m

Question:
Which product had the greatest percentage increase from Q1 to Q2?

A. Alpha
B. Beta
C. Gamma
D. Delta

Solution

Percentage increase = Increase ÷ Original × 100

Alpha:
55.2 − 48.0 = 7.2
7.2 ÷ 48.0 × 100 = 15.0%

Beta:
42.3 − 36.0 = 6.3
6.3 ÷ 36.0 × 100 = 17.5%

Gamma:
58.5 − 52.0 = 6.5
6.5 ÷ 52.0 × 100 = 12.5%

Delta:
50.6 − 44.0 = 6.6
6.6 ÷ 44.0 × 100 = 15.0%

Correct answer: B. Beta

Why This Is Tricky

Delta has the largest absolute increase, but Beta has the largest percentage increase.

This is one of the most common numerical reasoning traps.

Example 4: Net Sales After Refunds

A company reports gross sales and refund rates.

RegionGross SalesRefund Rate
North$94.0m6%
South$89.0m4%
East$78.0m7%
West$99.0m3%

Question:
Which region had the highest net sales after refunds?

A. North
B. South
C. East
D. West

Solution

Net sales = Gross sales × (1 − refund rate)

North:
94.0 × 0.94 = 88.36

South:
89.0 × 0.96 = 85.44

East:
78.0 × 0.93 = 72.54

West:
99.0 × 0.97 = 96.03

Correct answer: D. West

Why This Is Tricky

The question does not ask for gross sales. It asks for net sales after refunds.

A candidate who ignores the refund rate may still choose West here, but for the wrong reason. In harder questions, that shortcut will fail.

Worked Examples: Difficult Level

Example 5: Multi-Step Recruitment Data

A recruitment platform tracks applicants, interview rates and offer rates.

DepartmentApplicantsInterviewedOffer Rate from Interviewed
Finance1,20030%18%
Technology1,50024%20%
Operations90036%15%
Sales1,10028%22%

Question:
Which department made the highest number of offers?

A. Finance
B. Technology
C. Operations
D. Sales

Solution

First calculate interviewed candidates.

Finance:
1,200 × 30% = 360

Technology:
1,500 × 24% = 360

Operations:
900 × 36% = 324

Sales:
1,100 × 28% = 308

Now calculate offers.

Finance:
360 × 18% = 64.8

Technology:
360 × 20% = 72

Operations:
324 × 15% = 48.6

Sales:
308 × 22% = 67.76

Correct answer: B. Technology

Why This Is Tricky

Sales has the highest offer rate, but Technology has the highest number of offers.

The offer rate applies to interviewed candidates, not total applicants.

Example 6: Weighted Average

A training provider receives candidate ratings from three groups.

GroupNumber of CandidatesAverage Rating
Graduates1208.4
Interns808.9
Experienced Hires507.8

Question:
What is the overall average rating?

A. 8.30
B. 8.38
C. 8.43
D. 8.50

Solution

This is a weighted average.

Graduates:
120 × 8.4 = 1,008

Interns:
80 × 8.9 = 712

Experienced Hires:
50 × 7.8 = 390

Total weighted score:

1,008 + 712 + 390 = 2,110

Total candidates:

120 + 80 + 50 = 250

Overall average:

2,110 ÷ 250 = 8.44

Closest answer: 8.43

Correct answer: C. 8.43

Why This Is Tricky

You cannot simply average 8.4, 8.9 and 7.8 because the groups have different sizes.

Worked Examples: Expert Level

Example 7: Mixed Revenue, Cost and Margin

A company sells three subscription plans.

PlanCustomersMonthly PriceMonthly Cost per Customer
Basic8,000$12$5
Plus5,500$20$8
Premium2,400$35$14

Question:
Which plan generates the highest total monthly profit margin?

A. Basic
B. Plus
C. Premium
D. Basic and Premium are equal

Answer

Total monthly profit:

Basic:
8,000 × 7 = 56,000

Plus:
5,500 × 12 = 66,000

Premium:
2,400 × 21 = 50,400

Correct answer: B. Plus

Why This Is Tricky

Highest margin and highest total profit are not the same.

Premium has a high profit per customer, but Plus has more customers and therefore higher total profit.

Example 8: Compound Growth and Forecasting

A company’s revenue increased from $80m to $105.8m over three years.

Question:
What was the approximate compound annual growth rate?

A. 8%
B. 10%
C. 12%
D. 14%

Solution

CAGR = (Final ÷ Initial)^(1 ÷ years) − 1

Final ÷ Initial = 105.8 ÷ 80 = 1.3225

Now find the cube root because the period is three years.

1.10 × 1.10 × 1.10 = 1.331

So CAGR is approximately 10%.

Correct answer: B. 10%

Why This Is Tricky

A candidate may calculate total growth:

105.8 − 80 = 25.8

25.8 ÷ 80 × 100 = 32.25%

Then divide by 3:

32.25 ÷ 3 = 10.75%

That is close, but it is not compound annual growth. The correct compound rate is approximately 10%.

The 15 Most Common Reasons Candidates Fail SHL Numerical Tests

1. They read the table before reading the question

This wastes time and increases confusion.

2. They use the wrong base value

This is the most common percentage error.

3. They confuse percentage points with percentage change

A rise from 20% to 25% is 5 percentage points, not 5% growth.

4. They choose the largest number without checking the question

The largest revenue is not always the highest growth or margin.

5. They round too early

Rounding early can change the final answer.

6. They ignore units

Thousands, millions, dollars and euros can change the result.

7. They calculate too much

Sometimes estimation is faster and safer.

8. They do not check the chart scale

A bar chart may use intervals of 5, 10, 20 or 50.

9. They confuse revenue, cost and profit

These are different quantities.

10. They apply a percentage to the wrong group

For example, applying offer rate to applicants instead of interviewed candidates.

11. They miss footnotes

A footnote can change the meaning of the data.

12. They use the wrong exchange-rate direction

Currency questions often test multiplication vs division.

13. They panic under time pressure

Stress increases careless errors.

14. They do not review mistakes properly

Repeating questions without reviewing errors creates false confidence.

15. They practise generic maths instead of test-style data interpretation

SHL numerical reasoning is not just maths. It is timed data interpretation.

Time Management Strategy

The best timing strategy is not to rush every calculation.

Use three levels.

SituationStrategy
Answer options are far apartEstimate first
Answer options are closeCalculate carefully
Question is too denseLocate only the required data
You are stuckEliminate impossible answers
You have no timeMake the best-supported choice

Do not spend the same amount of time on every question. Some questions are designed to be solved quickly. Others require two or three steps.

Calculator Strategy

A calculator is not a substitute for reasoning.

Use it for:

  • multiplication,
  • division,
  • percentage calculation,
  • currency conversion,
  • weighted averages.

Do not use it blindly.

Before entering numbers, know:

  • what formula you are using,
  • which value is the base,
  • what unit the answer should have,
  • whether the answer should be bigger or smaller than the original value.

Estimation Strategy

Estimation is useful when answer options are not close.

Example:

19.8% of 502 is approximately 20% of 500 = 100.

If answer options are:

A. 52
B. 98
C. 151
D. 204

You can choose B without exact calculation.

If answer options are:

A. 97.8
B. 99.4
C. 100.1
D. 101.6

You need exact calculation.

ReasoningCampus Numerical Difficulty Index

What Is Included in ReasoningCampus SHL Numerical Practice?

ReasoningCampus numerical practice is designed for candidates who want structured preparation instead of random maths drills.

It includes:

  • SHL-style numerical questions,
  • table interpretation practice,
  • graph interpretation practice,
  • percentage-change drills,
  • ratio and proportion questions,
  • currency conversion questions,
  • profit and margin questions,
  • timed practice,
  • worked explanations,
  • wrong-answer analysis,
  • formula review,
  • difficulty levels,
  • mixed mock practice.

Each explanation shows:

  • what the question asks,
  • which data matters,
  • which formula to use,
  • how to calculate,
  • why the correct answer is correct,
  • why the wrong answers are tempting.

Why ReasoningCampus Practice Is Different

Many candidates practise numerical reasoning by answering questions and checking only the final answer.

That is not enough.

ReasoningCampus focuses on:

  1. Method
    You learn a repeatable way to approach numerical questions.
  2. Accuracy
    You learn to avoid wrong rows, wrong bases, wrong units and wrong calculations.
  3. Timing
    You learn when to calculate exactly, when to estimate and when to eliminate.
  4. Error Review
    You learn why you made the mistake so you can stop repeating it.
  5. Transfer
    You learn how to solve unfamiliar questions, not just the examples you have already seen.

Should You Use SHL Direct Practice?

Yes. SHL Direct is useful because it helps you understand official candidate-facing examples and practice-test formats. SHL Direct provides numerical reasoning example questions and practice-test information for candidates.

However, official familiarisation alone may not be enough for many candidates.

You may also need:

  • more question variety,
  • full worked explanations,
  • topic-by-topic practice,
  • timed practice,
  • mistake review,
  • formula revision,
  • interactive-style training.

Use official practice to understand the environment. Use structured practice to improve the skill.

Scientific Background: What Numerical Reasoning Measures

Numerical reasoning is connected to broader cognitive ability testing because it requires working with information, choosing relevant data and making correct decisions under constraints.

In psychometric testing, modern ability assessment may use statistical models to estimate ability from item responses. Item Response Theory is widely used in educational and psychological measurement to model how people respond to test items and how item difficulty relates to ability.

Computerized adaptive testing can use previous responses to select later items that better estimate a test-taker’s level. This is why adaptive tests can feel harder after correct answers and why timing and composure matter.

For candidates, this means preparation should focus on transferable skills:

  • accuracy,
  • speed,
  • data interpretation,
  • error control,
  • calculation discipline,
  • calm decision-making under time pressure.

Prepare by Employer, Industry and Role

Some candidates search for SHL numerical practice by employer or role.

Common searches include:

  • Amazon SHL Numerical Test,
  • PwC Numerical Reasoning Test,
  • EY Numerical Test,
  • KPMG Numerical Reasoning,
  • Deloitte Numerical Test,
  • HSBC Numerical Reasoning,
  • Shell Numerical Test,
  • Unilever Numerical Assessment,
  • Nestlé Numerical Reasoning,
  • Accenture Numerical Test,
  • investment banking numerical test,
  • consulting numerical reasoning test,
  • engineering numerical aptitude test,
  • graduate numerical reasoning test,
  • internship numerical assessment.

Always check your own assessment invitation. The employer name alone does not guarantee a specific test version.

Other Numerical Test Providers

SHL is not the only provider of numerical reasoning assessments.

Candidates may also encounter numerical or cognitive assessments from:

  • Aon,
  • Korn Ferry,
  • Saville,
  • Cappfinity,
  • TalentQ,
  • Pearson,
  • Mercer,
  • Thomas International,
  • Cubiks,
  • Revelian.

The core skills often overlap: data interpretation, percentages, ratios, comparisons and timed reasoning. The interface, scoring and question style may differ.

Other SHL Tests You May Need

Many candidates who take SHL numerical reasoning also need to prepare for other SHL-style assessments.

Related tests include:

  • SHL Inductive Reasoning,
  • SHL Deductive Reasoning,
  • SHL Verbal Reasoning,
  • SHL General Ability / Verify G+,
  • SHL Calculation Test,
  • SHL Checking Test,
  • SHL Situational Judgement Test,
  • SHL Personality Questionnaire.

If your assessment is a broader ability test, practise more than numerical reasoning.

What to Do If You Run Out of Time

If time is running out:

  1. Read the question carefully.
  2. Identify the exact data needed.
  3. Estimate if answer options are far apart.
  4. Eliminate impossible answers.
  5. Choose the best-supported option.

Do not panic and do not start calculating randomly.

A calm estimate is often better than a rushed exact calculation using the wrong data.

What to Do the Day Before the Test

The day before your assessment, do not try to learn everything from zero.

Focus on:

  • percentage change,
  • ratios,
  • averages,
  • weighted averages,
  • table reading,
  • chart scales,
  • calculator accuracy,
  • your most common mistakes.

Complete one timed mixed practice set, then review your errors slowly.

The goal is to enter the test calm, accurate and familiar with the question types.

Frequently Asked Questions

What does the SHL Numerical Reasoning Test measure?

It measures your ability to interpret numerical data, analyse tables and charts, perform calculations and make accurate decisions under time pressure.

Is SHL numerical reasoning the same as maths?

No. It uses basic maths, but the main skill is data interpretation. You must read the right figures, choose the right calculation and avoid traps.

What maths do I need?

You should know percentages, percentage change, ratios, averages, weighted averages, profit, margin, currency conversion, growth rates and basic data interpretation.

Can I use a calculator?

SHL support says candidates completing a numerical or calculation test may use a calculator unless instructed otherwise. Always follow your own assessment instructions.

Can I go back to previous questions?

In some adaptive SHL assessment contexts, you cannot return to previous questions after submitting an answer because later question difficulty may depend on previous answers.

How hard is the SHL Numerical Reasoning Test?

It can be difficult because of time pressure, dense data, close answer options and multi-step calculations. The maths is usually manageable, but the test requires accuracy and speed.

What is the best way to prepare?

The best way is to learn the core formulas, practise by question type, review mistakes carefully and then complete timed mixed practice.

Are SHL numerical questions the same for every candidate?

No. Candidates may receive different formats, question sets or assessment versions depending on the employer and platform.

Does ReasoningCampus provide official SHL questions?

No. ReasoningCampus provides independent SHL-style practice and learning resources. It is not affiliated with SHL and does not provide official live SHL test questions.

Final advice for the exams

SHL numerical reasoning is not about being a mathematician.

It is about staying accurate when the data is dense, the time is limited and the answer options are close.

Use a clear method:

Read the question.
Locate the right data.
Choose the correct formula.
Calculate carefully.
Check the unit.
Eliminate wrong answers.
Answer with confidence.

Every practice question should teach you one of three things:

  • a formula you need to use correctly,
  • a data trap you need to avoid,
  • an error pattern you need to fix.

Once you understand how SHL-style numerical reasoning questions are built, the test becomes less intimidating. You stop calculating randomly and start solving strategically.
