About Logical Reasoning TestsLogical reasoning tests (in the sense of employers' online assessments) usually consist of abstract, diagrammatic or inductive reasoning tests. Employers often use these tests as part of their online selection process. It would be easier to describe logical tests as non verbal reasoning tests, since they do not present you with verbal or numerical information but instead with shape sequences and the logical patterns that they represent.
Here are a few quick links to information about logical reasoning tests published by the leading assessment companies:
Note though, that the term logical reasoning is also used to describe verbal logical reasoning tests. These are used in many undergraduate and graduate admissions tests and in certain selection processes. Scroll down to see some verbal logical reasoning questions.
Verbal Logical Reasoning QuestionsHere are four examples of verbal logical reasoning questions. Choose the correct answer for each question:
(1) Choose the image that completes the pattern.
Each square contains 3 shapes. The black circle is the only shape that constantly appears. It “travels” along the column up and down, one step at a time. The other shapes appear in two consecutive squares, and then do not appear in the next square. The shape that remains in the frame (in regards to the last step from the left) maintains its relative position to the other shape (not the circle).
(2) If there are no dancers that aren’t slim and no singers that aren’t dancers, then which statements are always true?
- There is not one slim person that isn't a dancer
- All singers are slim
- Anybody slim is also a singer
- None of the above
The tricky part here is that the question is phrased negatively. This means that we first of all need to identify the nature of each group, and then establish the relationship between the groups. If we draw ourselves a diagram (as in the example above), the relationship between the groups becomes clearer. The only true statement is that all singers are slim.
The answer is 'All singers are slim'.
(3) Dan is Joshua's son and Guy's brother. Margaret is Guy's mother and Judy's daughter. Which of the statements below is definitely true?
- Judy is Dan's mother-in-law
- Margaret is Dan's mother
- Judy is Joshua's grandmother
- None of the above
Dan and Guy are siblings, however, we do not know whether they are full siblings or half brothers. Margaret, who is Guy's mother, might not be Dan's mother, and Joshua, who is Dan's father, might not be Guy's father.
Therefore, the answer is: 'None of the above.
(4) This is data supplied by the cabbage growers union report for 2007: 80% of cabbages collected were heavy (over 0.5 kg), 10% of cabbages were green, 60% were red and 50% were big (having a diameter of over 10 cm). Which of the following statements must be false?
- All red cabbages weren’t big
- 30% of red cabbages were big
- There were no cabbages that were both green and big
- Half of the cabbages were small
You have to check the authenticity of each statement.
The answer is 'All red cabbages weren’t big'.
All red cabbages weren’t big: We know that 60% of cabbages picked were red and only 50% were big. Therefore, there is an overlap (60% + 50% = 110% > 100%). The statement must be false, so we can assume that this is the correct answer. But let's check the rest of the statements in any case.
30% of red cabbages were big: We know that 60% of cabbages were red and 50% were big, so there must be an overlap of at least 10% (60% + 50% = 110% > 100%). However, we don’t know the extent of the overlap. This statement may be true, but we don’t know for sure. Remember, the question asks us which statement must be false.
There were no cabbages that were both green and big: We know that 10% of the cabbages were green and 50% were big, so there may not be an overlap between the two (10% + 50% = 60% < 100%). This statement can be ruled out, as it may or may not be false. We're only looking for a statement that must be false.
Half of the cabbages were small. We know that 50% (i.e. one half) of the cabbages are big, so the other half may be small. This would make this statement true. And remember, we're looking for a false statement.
