Numerical reasoning tests measure how accurately you can use information presented in tables, charts and short business scenarios. The arithmetic is usually familiar; the challenge is deciding which figures matter, choosing the right operation and completing it under time pressure.
The fastest improvement normally comes from practising the full process rather than memorising formulas in isolation. You need to read the question first, extract only the required data, estimate the likely answer and then calculate carefully.
Key points
- Read the question before studying every number in the chart.
- Practise percentages, ratios, averages and rates until the setup feels automatic.
- Use estimation to reject implausible options before doing precise arithmetic.
- Review the method behind each mistake, not only the correct answer.
01
What numerical reasoning questions test
A typical question gives you more information than you need. Strong candidates separate the decision from the calculation: first define exactly what must be found, then identify the baseline, comparison period and unit. This prevents common errors such as dividing by the new value instead of the original value.
Expect percentages, percentage change, ratios, proportions, averages, totals, currency conversion and speed or productivity rates. A graph may look different from a table, but the underlying calculation is often one of these familiar patterns.
02
A reliable four-step method
Use the same sequence on every question: identify the output, select the inputs, choose the operation and check the result. Writing a short calculation structure before entering numbers reduces rework and helps you spot missing units.
- Output: What exactly must the answer represent?
- Inputs: Which row, column, period or category supplies the figures?
- Operation: Is this a difference, percentage, ratio, average or rate?
- Check: Does the size, sign and unit of the answer make sense?

How to improve your score
Begin in learn mode so you can concentrate on method. Once your working is consistent, use timed sets and decide in advance how long you will spend before moving on. A difficult question should not consume the time available for several easier ones.
Keep a short error log with categories such as wrong data, wrong operation, arithmetic slip and time pressure. This turns practice results into a focused revision plan and makes your next session more valuable.
A support team completed 1,200 requests in April and 1,380 in May.
What was the percentage increase from April to May?
- A12%
- B15%
- C18%
- D20%
The increase is 1,380 − 1,200 = 180. Divide 180 by the April baseline of 1,200, then multiply by 100: 180 ÷ 1,200 × 100 = 15%.

Frequently asked questions
Can I use a calculator in a numerical reasoning test?
It depends on the test instructions. Practise both with and without one, and always check the rules shown before your assessment begins.
What maths should I revise?
Prioritise percentages, ratios, fractions, averages, rates, interpreting charts and choosing the correct baseline.
How can I work faster?
Improve setup speed first. Reading the question before the data and estimating the answer usually saves more time than rushing the arithmetic.
