AonAptitude

Aon Applied Numeracy practice test

Practical arithmetic against a clock: convert the unit, scale the quantity, take the percentage, find the area. No calculator dexterity required — just no slips.

Free to start. Every item is generated fresh, marked with a full worked solution, and ranked on a 1–9 stanine band that recalibrates as more candidates practise.

A real item

Two questions from the exercise itself

Not a mock-up. The items below were produced by the same generator that runs inside the app, with the solution derived from the same model that built the question — which is why the answer key cannot drift from the item.

A vehicle uses 11 litres of fuel per 100 km. How many litres does it use over 300 km?

  1. A14 l
  2. B3,300 l
  3. C2,727 l
  4. D33 lAnswer

How it is solved

  • 1.First find the value for one unit, then scale it.
  • 2.Calculation: 11 ÷ 100 × 300 = 33 l

A price of 625 € rises by 8%. What is the new price?

  1. A633 €
  2. B675 €Answer
  3. C575 €
  4. D50 €

How it is solved

  • 1.Calculation: 625 × 1.08 = 675 €

What it measures

What Applied Numeracy is actually testing

Applied numeracy measures reliable everyday arithmetic at speed: whether you can convert between units, scale a quantity proportionally, take or reverse a percentage, and compute a simple area without dropping a factor of ten. It is the module that filters on carelessness rather than ability.

The format

How the real assessment runs

Format
Short sections grouped by topic — units, rule of three, percentages, areas — with several quick items in each.
Timing
Tight. Individual items take fifteen to thirty seconds; the pressure comes from volume.
Numbers
Deliberately clean. If your arithmetic is getting ugly you have almost certainly set the problem up wrong.
Marking
Number correct within the time. Unfinished items score nothing, so pace matters as much as accuracy.

Where marks are lost

The trap that costs the most marks

Reversing a percentage by subtracting it. A price that rose 20% does not come back with a 20% cut, and a figure that is 80% of another is not 120% the other way. The second most common slip is a factor of ten in unit conversion — cm² to m² is ten thousand, not a hundred.

Why practise here

What this practice gives you

01

Four topic sections that mirror the way cut-e groups the module

02

Every item shows the setup line, not just the result — the setup is where marks are lost

03

Reverse-percentage and compound-change items included, since those are the ones that separate candidates

04

Clean numbers throughout, so you practise the method rather than long division

05

A stanine band per run, recalibrated as the candidate pool grows

Everything you need to walk in ready

One subscription covers the whole assessment library, not just this exercise — because almost nobody is invited to sit only one module.

The full aptitude library

SHL Verify, Aon cut-e, Hogan and Saville formats — numerical, verbal, inductive, deductive, mechanical, checking and the interactive modules.

A rank, not just a score

Every run is placed on a 1–9 stanine band that recalibrates as the candidate pool grows, so you know your position.

A course per exercise

What it measures, the trap that costs marks, and worked items from every format — then the exercise itself.

Unlimited fresh items

Everything is generated, so you never run out and never memorise a bank.

Written + voice AI coach

Reads your results across exercises and tells you which two to fix first.

Applied Numeracyfrequently asked questions

What is applied numeracy in the Aon cut-e battery?

Applied numeracy tests practical everyday arithmetic at speed: unit conversion, proportional scaling (rule of three), percentages, and simple areas. It is grouped into short topic sections and filters on carelessness rather than mathematical ability.

How do you reverse a percentage correctly?

Divide, do not subtract. A price that rose 20% returns to its original by dividing by 1.2, which is a cut of about 16.7%, not 20%. Reverse-percentage items are among the most reliably failed on this module, so this practice includes them deliberately.

Is a calculator allowed on Aon applied numeracy?

Administrations vary and many provide an on-screen calculator. The numbers are chosen to be clean either way — if your arithmetic is turning ugly, the setup is usually wrong rather than the sum being hard.
