Logical Reasoning

Series, assumptions, conclusions and arguments — pure logical analysis.

Logical reasoning tests how you analyse a statement rather than how fast you calculate. The topics divide into two families: pattern questions, where you work out the rule behind a sequence or a grouping, and argument questions, where you decide what a statement does and does not commit its author to. The second family is where most candidates lose marks, because they answer from general opinion instead of the text on the page.

How to prepare Logical Reasoning

  • For pattern questions, always write the gaps or the differences down instead of staring at the sequence.
  • For argument questions, separate what is stated from what you happen to believe about the subject.
  • In assumption questions, ask what the author must have believed for the statement to make sense at all.
  • In conclusion questions, reject any option that needs outside information, however true that information may be.
  • Practise in short sets. Reasoning is a skill of attention, and accuracy falls off quickly after about twenty minutes.

Logical Reasoning — frequently asked questions

What is the difference between Statement and Assumption and Statement and Conclusion?

In Statement and Assumption you look for the belief the author took for granted while making the statement. In Statement and Conclusion you decide whether a conclusion follows strictly from the given statement.

How do I improve at number and letter series?

Write the differences between consecutive terms. If those differences form a pattern, you have the rule. If they do not, check the ratios, then check whether the terms are near squares or cubes.

Should I guess in reasoning questions?

Only if the paper has no negative marking, or if you can eliminate at least two options. Reasoning options are designed so that a casual reading lands on a plausible wrong answer.

Is logical reasoning the same as verbal reasoning?

No. Logical reasoning works on sequences, statements and arguments. Verbal reasoning covers arrangements, coded relationships, direction sense and similar puzzles that use language mainly as a carrier of clues.
