Worked examples: how to reason through AON questions
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Example 1
Question: In the matrix Row 1=(2,4,8) and Row 2=(3,9,27), following the same rule, what is the missing third value in Row 3 starting with 4 and 16?
- 48
- 64
- 32
- 56
Answer: B. 64
Explanation:
The correct answer is 64. Each row uses consecutive powers of its first value: the first row is 2 raised to the first, second and third powers, and the second row follows the same pattern with its own first value. Row 3 starts with 4 and 16, so the third value is 4 to the third power, which is 64.
48 is wrong because it comes from multiplying 16 by 3, which is not the row rule. 32 is wrong because it doubles 16, which ignores the pattern. 56 is wrong because it only adds to 16 and fits no rule in the earlier rows.
Rule to remember: test one rule against every complete row before applying it to the incomplete one. Check both multiplication and powers.
Example 2
Question: You are given an urgent task but realize you lack the knowledge to complete it. What should you do?
- Guess at an answer to appear competent.
- Admit the gap to your manager and ask for guidance or resources.
- Delegate the task to a junior colleague without their preparation.
- Wait until someone notices you haven't started.
Answer: B. Admit the gap to your manager and ask for guidance or resources.
Explanation:
The correct answer is to admit the gap to your manager and ask for guidance or resources. This deals with the problem early and keeps the work on track.
Guessing to appear competent is wrong because a confident but incorrect result can cause more harm than a short delay. Delegating to a junior colleague without preparation is wrong because it passes your problem to someone who has not been set up to handle it. Waiting until someone notices is wrong because it hides the issue and wastes time on an urgent task.
Rule to remember: in situational judgment questions, the strongest answer is usually honest, timely and constructive. It involves the right people and does not shift responsibility or conceal a problem.
Example 3
Question: Two gears are connected. Gear A has 40 teeth and Gear B has 20 teeth. If Gear A rotates at 30 RPM, how fast does Gear B rotate?
- 15 RPM
- 30 RPM
- 60 RPM
- 120 RPM
Answer: C. 60 RPM
Explanation:
The correct answer is 60 RPM. Meshed gears have speeds inversely proportional to their tooth counts. Gear A has 40 teeth and Gear B has 20, so B is the smaller gear and turns faster. Multiply 30 by 40/20 to get 60 RPM.
15 RPM is wrong because it reverses the ratio, as if the smaller gear turned slower. 30 RPM is wrong because it assumes the gears share a speed, which is only true when the tooth counts match. 120 RPM is wrong because it doubles the correct result, for example by applying the ratio twice.
Rule to remember: the smaller gear spins faster, and the speed ratio equals the inverse of the tooth ratio.
How to use these practice tests
Start with Aon's official preparation page and your invitation. Note which tests you have been asked to take, the deadline, and which tests are timed. Then build your practice around those.
- Take one set untimed first, so you learn the question types. Good starting points are AON Numerical Reasoning and AON Verbal Reasoning.
- Repeat the set under a timer. Numerical and verbal tests reward finishing as many tasks as you can, so practise skipping a slow question and returning to it.
- If your role involves mechanical tasks, work through AON Mechanical and Spatial Reasoning. Write down the rule behind each missed question, such as the gear speed ratio.
- Try AON Abstract Reasoning, AON Inductive Reasoning and AON Deductive Reasoning for pattern and logic practice.
- Use AON Situational Judgment to practise choosing honest, practical responses at work.
For the personality questionnaire, there are no right answers to rehearse. Answer consistently and honestly. Because you may repeat a module at interview, work in a way you can reproduce. Spread your sessions across several days and do the real tests when you are rested and undisturbed.
- ✓Review the official AON exam content outline
- ✓Take a diagnostic practice test to identify weak areas
- ✓Create a study schedule (4-8 weeks recommended)
- ✓Focus on your weakest domains first
- ✓Complete at least 3 full-length practice exams
- ✓Review all incorrect answers with detailed explanations
- ✓Take a final practice test 1 week before exam day
AON Assessment Test
Whether you are applying for a job, re-entering the workforce or just want to make sure you are up to par with your peers, an AON assessment test is a great way to go. It helps you determine your strengths and weaknesses, and it is also a good way for employers to see whether you're a good fit for the company.
There are several types of AON tests, including numerical reasoning and spatial orientation tests. These tests measure a variety of skills, including numerical skills, spatial skills and deductive reasoning.
Aon's Spatial Orientation Test has the following features: It tests your ability to understand spatial relationships and your ability to determine the location of objects. It also measures your ability to use mathematical concepts and work with data.
Aon's Numerical Ability Test is quite challenging, and requires you to quickly tally up numbers to determine the right answer. It also tests your ability to recognize and use numeric data and graphs.
While Aon's Aon Assessment test is one of the more complicated tests, it is a great way to determine whether you have what it takes to succeed in your next job.

📋 What is the Aon assessment?
The Aon assessment is an online pre-employment test from Aon's Assessment Solutions (formerly cut-e). It usually combines several ability tests and questionnaires, completed online during recruitment, to show the hiring company how well you fit the job.
START AON PRACTICE TEST⏱️ How long does the Aon assessment take?
It depends on the employer and role. In most cases you complete no more than five tests, and each individual test usually lasts under 15 minutes. Your invitation email states how much time you will need.
START AON QUIZ🔢 What numerical tests are in the Aon assessment?
Aon's numerical tests include scales numerical (numerical reasoning), scales eql (basic numerical comprehension) and digitChallenge (numeracy). For some tests a calculator or pen and paper helps; the test introduction tells you if an aid is allowed.
START NUMERICAL PRACTICE TEST📖 What is the Aon verbal reasoning test?
scales verbal is Aon's verbal reasoning test. Related verbal tests are scales verbal instruct, which checks understanding of basic instructions, and scales lt, which measures language skills. Employers pick the tests that match the job.
START VERBAL PRACTICE TEST🔀 What is the Aon switchChallenge test?
switchChallenge is Aon's game-based deductive reasoning test, and gapChallenge measures deductive-logical thinking. Like other Aon ability tests it is timed, and it starts with untimed instructions and example tasks.
START DEDUCTIVE PRACTICE TEST🔍 What are Aon scales ix, clx and cls?
All three are Aon inductive reasoning tests. scales ix measures inductive reasoning, scales clx measures inductive logical reasoning and scales cls measures inductive-logical thinking. In each one you spot the rule behind a pattern of figures.
START INDUCTIVE PRACTICE TEST🧠 What is the Aon gridChallenge?
gridChallenge is Aon's working memory test, delivered in a game-like format. Aon also uses motionChallenge for complex planning, scales e3+ for concentration and scales mtu for mechanical reasoning.
START MECHANICAL PRACTICE TEST🧭 What is the ADEPT-15 personality test?
ADEPT-15 is Aon's work-behaviour personality questionnaire, built on 15 behavioural dimensions. There are no right or wrong answers, and personality questionnaires normally have no time limit, so answer honestly.
START SITUATIONAL JUDGMENT TEST✅ How is the Aon assessment scored?
On ability tests you usually gain points for each correct answer and lose points for each wrong one. Work quickly but carefully, and don't guess wildly. It is normal not to finish every question in the time allowed.
START AON PRACTICE TEST⏸️ Can you pause the Aon assessment?
No. Once a test starts you cannot pause it. You don't have to take every test in one sitting, though, and you usually have several days to finish before the deadline in your invitation. If a test gets blocked, ask the employer to unblock it.
