Numerical ability test 01

 

 

In this test you are given numbers that connect in some way. They connect along the row, but there is also a relationship with the numbers that are above or below each other. Sometimes a number is missing and a space mark, or line ( – ), has been put in its place. One of the numbers has been replaced by a question mark ( ? ).

From the information given, you have to find the number that would replace the question mark.

 

Example 1

1 – 3 ?

– 4 6 8                                              Answer =

 

The most logical answer is 4; it fits the sequence 1, 2, 3, 4 because a 2 could replace the space mark. Also, 4 is half of 8, in the same way that 3 is half of 6, 2 is half of 4, and 1 is half of 2. The answer, 4, makes all the numbers fit together logically.

 

1 2 3 4

2 4 6 8                                               Answer = 4

 

Example 2

1 – 9 ?

2 6 – 54                                            Answer =

The numbers in the lower line are always twice the number in the line above. Also, from left to right, each number is  multiplied three times.

1 3 9 27

2 6 18 54                                           Answer = 27

Working out the correct numbers for the empty spaces can help you find the number that can replace the question mark. You have eight minutes to do as many as you can. It is important to work as quickly as possible in order to get as many right as possible in the time allowed.
