Numerical computation questions involve the basic principles of arithmetic like addition, subtraction, multiplication and division. They also use mathematical terms and methods such as percentages, ratios, fractions and decimals. To score well on numerical computation questions you will need to make quick and accurate calculations.
This type of test can be categorized as a speed test and is used to determine your basic numeracy. Obviously you will not be allowed to use a calculator.

Answer to these sample Numerical Computation questions.
If you are very rusty with arithmetic, try relearning the
times tables up to 12 and practice multiplication, division and
percentage calculations. Practice can improve your test scores
for all types of aptitude tests, so try as many examples as you
can.
These questions are directly applicable to many administrative
and clerical jobs but can also appear as a component of graduate
and managerial tests. The speed at which you can answer these
questions is the critical measure, as most people could achieve
a very high score given unlimited time in which to answer. You
can therefore expect 2535 questions in 2030 minutes.
These papers contain 30 questions and have a suggested time
limit of 10 minutes each. The questions are presented in
Letter/A4 format for easy printing and selfmarking.

Numerical ability tests can be divided into tests of simple
numeracy, where you are told which arithmetic operations to apply,
and numerical reasoning tests where you are presented with some
data and questions but the methods required to answer the
questions are not specified. In all cases you need to prepare by
practicing your mental arithmetic until you are both quick and
confident. Your score in the simple speed tests will be very much
influenced by your ability to add, subtract, multiply and divide
quickly and accurately.
Preparation plays a large part in determining your level of
success, and these sample questions should help you to face a test
with increased confidence.
