Logical Reasoning or LR is one of the most important sections of all MBA entrances exams. In CAT, it is clubbed with Data Interpretation, whereas in other exams, it is clubbed with Quantitative Aptitude or Verbal Reasoning. Of all the MBA entrance exams, MAH MBA CET has the maximum number of reasoning question, i.e 100.

Logical Reasoning is one of the high scoring sections of management aptitude tests. You can score full marks if you get it correct. However, it is tough to prepare as there are no formulae to be memorised or techniques to be applied. Solving LR questions accurately is possible only by learning logical analysis of the problem and its possible solution.

A Logical Reasoning question is rarely straightforward. It is challenging to find out the hidden information that leads to the right answer. Thus, the only approach to Logical Reasoning is by filtering out irrelevant data. Let’s understand all about Logical Reasoning.

What is Logical Reasoning?

Logical Reasoning can be understood as brainteasers, which require common sense and logical thinking. It is categorised in to two types:

Verbal Reasoning: It is the ability to logically understand the concepts and find the solution of the problems expressed in words. Verbal Reasoning requires a good command on the language for understanding the question and extraction of information.

Non-verbal Reasoning: It is the ability to logically understand the concepts and find solution of the problems presented in a combination of numbers/letters/figures and words. Non-Verbal Reasoning problems can be solved by deduction and induction of logic of information and implications in a problem.
