# Aptitude Tests : Additional Numerical Aptitude Tests Questions Samples

## Additional Numerical Aptitude Tests Questions Samples

The first type of numerical ability or aptitude test covers basic arithmetic (addition, subtraction multiplication and division), number sequences and simple mathematics (percentages, powers, fractions, etc). 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.

## Arithmetic Questions

1. 139 + 235 =

• A) 372

• B) 374

• C) 376

• D) 437

2. 139 - 235 =

• A) -69

• B) 96

• C) 98

• D) -96

3. 5 x 16 =

• A) 80

• B) 86

• C) 88

• D) 78

4. 45 / 9 =

• A) 4.5

• B) 4

• C) 5

• D) 6

5. 15% of 300 =

• A) 20

• B) 45

• C) 40

• D) 35

6. ½ + ¼ x 3/4 =

• A) 3/8

• B) 13/8

• C) 11/16

• D) 3/4

1. B
2. D
3. A
4. C
5. B
6. C

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 25-35 questions in 20-30 minutes.

## Number Sequences

These questions require you to find the missing number in a sequence of numbers. This missing number may be at the beginning or middle but is usually at the end.

7. Find the next number in the series

4, 8, 16, 32, —

• A) 48

• B) 64

• C) 40

• D) 46

8. Find the next number in the series

4, 8, 12, 20, —

• A) 32

• B) 34

• C) 36

• D) 38

9. Find the missing number in the series

54, 49, — 39, 34

• A) 47

• B) 44

• C) 45

• D) 46

10. Find the first number in the series

— 19, 23, 29, 31,

• A) 12

• B) 15

• C) 16

• D) 17

These number sequences can be quite simple like the examples above. However, you will often see more complex questions where it is the interval between the numbers that is the key to the sequence

11. Find the next number in the series

3, 6, 11, 18 —

• A) 30

• B) 22

• C) 27

• D) 29

12. Find the next number in the series

48, 46, 42, 38, —

• A) 32

• B) 30

• C) 33

• D) 34

These number sequences usually consist of four visible numbers plus one missing number. This is because the test designer needs to produce a sequence into which only one number will fit. The need to avoid any ambiguity means that if the number sequence relies on a more complex pattern then there will need to be more visible numbers. For example;

13. Find the missing number in the series.

4, 3, 5, 9, 12, 17, —

• A) 32

• B) 30

• C) 24

• D) 26

14. Find the missing numbers in the series

5, 6, 7, 8, 10, 11, 14, —, —

• A) 19

• B) 17

• C) 15

• D) 16

15. Find the missing numbers in the series

1, —, 4, 7, 7, 8, 10, 9, —

• A) 6

• B) 3

• C) 11

• D) 13

7. B – The numbers double each time
8. A – Each number is the sum of the previous two numbers
9. B – The numbers decrease by 5 each time
10. D – The numbers are primes (divisible only by 1 and themselves)
11. C – The interval, beginning with 3, increases by 2 each time
12. B – The interval, beginning with 2, increases by 2 and is subtracted each time
13. D – Each number is the sum of the previous and the number 3 places to the left
14. C A – There are 2 simple interleaved sequences 5,7,10,14,19 and 6,8,11,15
15. A D – There are 2 simple interleaved sequences 1,4,7,10,13 and 6,7,8,9

To solve these number sequence questions efficiently, you should first check the relationship between the numbers themselves looking for some simple arithmetic relationship. Then look at the intervals between the numbers and see if there is a relationship there. If not, and particularly if there are more than 4 numbers visible, then there may be two number sequences interleaved.

You will occasionally find multiplication, division, or powers used in these sequences, but test designers tend to avoid them as these operations soon lead to large numbers which are difficult to work out without a calculator.

## Letter of the Alphabet as Numbers

Another type of sequence question which appears in these tests involves the substitution of letters of the alphabet for numbers. For example A=1, B=2 etc. It may seem strange to consider these as numerical reasoning questions but they actually work in the same way once you have changed them back into numbers.

16. Find the next letter in the series

B, E, H, K, —

• i) L

• ii) M

• iii) N

• iv) O

17. Find the next letter in the series

A, Z, B, Y, —

• i) C

• ii) X

• iii) D

• iv) Y

18. Find the next letter in the series

T, V, X, Z, —

• i) Y

• ii) B

• iii) A

• iv) W

• 16. iii – There are two letters missing between each one, so N is next

• 17. i – There are 2 interleaved sequences A,B,C and Z,Y, so C is next

• 18. ii – Miss a letter each time and ‘loop’ back, so B is next

Because arithmetic operations cannot be performed on letters there is less room for ambiguity in these questions. This means that interleaved sequences can be used with fewer visible letters than in questions that use numbers. Question 17 for example can use 2 interleaved sequences even though only four letters are visible. This would be very difficult to achieve with numbers.

It is implicit in these ‘alphabetic sequence’ questions that the sequence ‘loops’ back around and starts again. See question 18. It is important to recognize this as it is not usually stated explicitly – you are just expected to know it.

If you see more than one of these questions in a test then it is almost certainly worth taking the time to write out the letters of the alphabet with their ordinal numbers underneath. You can then treat these questions in a similar way to number sequence questions. This can save a lot of time overall and avoid simple mistakes.

## Data Interpretation

Information is provided that requires you to interpret it and then apply the appropriate logic to answer the questions. Sometimes the questions are designed to approximate the type of reasoning required in the workplace. These data interpretation questions will often use very specific illustrations, for example the question may present financial data
or use information technology jargon. However, an understanding of these areas is not required to answer the question.
