      Numerical awareness questions take a closer look at your ability to add, subtract, multiply and divide. Numerical estimation appraises your potential for estimating both quickly and accurately, which may be a key requirement for the job. Numerical checking evaluates your aptitude for spotting errors in handwritten and printed data. Here are various example questions and answers.

       Example: Adding and Subtracting

      Do the following calculation, without using a calculator.

      Question: 295 − 97 + 123 − 33 + 17 =

      Answer: 305

       Example: Multiplying and Dividing

      Answer the following question without the aid of a calculator.

      Question: 18 x 9 ÷ 3 =

      Answer: 54

       Example: Fractions and Percentages

      Calculate the following.

      Question: 6% of 75 =

      Answer: 4.5

       Example: Continuing a Series of Numbers

      Complete this sequence of numbers.

      Question: 7 12 16 19 21 ____

      Answer: 22 (Numbers increase at a decreasing rate: +5, +4, +3, +2, +1.)

       Example: Numerical Awareness

      Circle any mistakes in these calculations, and put in the correct figures next to them.

      Question:

      Answer:

       Example: Numerical Estimation

      Calculate the following, placing a cross (X) in the box representing the figure that is nearest to your answer.

      Question: A man walks 3.5 miles per hour for five hours each day. How long would it take him to complete a 127-mile journey?

      

5 days
6 days
7 days
8 days
9 days
10 days

      Answer: 7 days

(3.5 miles per hour x 5 hours per day = 17.5 miles per day. 127 miles ÷ 17.5 miles per day = 7.26 days)

       Example: Numerical Checking

      Circle any differences in these lists.

      

      Question:

1. 378963/43	1. 378963/47
2. 949494/46	2. 944949/46
3. 327272/77	3. 327272/77
4. 411114/31	4. 411144/31
5. 696692/26	5. 696992/26

      Answer:

      Spatial Ability Questions

      Your spatial ability – or lack of it – may be estimated by the way in which you answer questions involving shapes. Typically, you will have to fit shapes together, imagine how a flattened shape would appear when folded to create a solid object and visualize how a solid object would look when unfolded. Sometimes, spatial ability questions can be quite diverse in nature, as may be seen by these example questions and answers.

       Example: Fitting Shapes Together

      Identify the shapes which fit together by underlining the appropriate letter.

      Question:

      Answer:

       Example: Creating Solid Objects

      Question: Identify the solid object created by folding together the flat pattern, by circling the relevant letter.

      Answer:

       Example: Unfolding Solid Objects

      Question: Indicate how the solid object will look unfolded, by underlining the appropriate letter.
