What is Logical Reasoning?
Logical Reasoning is like brainteasers, which require common sense and logical thinking. It is categorised into two types:
Verbal Reasoning: It is the ability to logically understand the concepts and find solution to the problems expressed in words. Verbal Reasoning requires a good command on the language for understanding the question and extraction of information. The answers are often hidden in the question. Sometimes, one has to follow the logic and order of the given situation to derive the answer.
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. This includes visual reasoning and analytical reasoning. The challenge lies in reading the pattern correctly after considering all possible combinations and dimensions. Abstract Reasoning is also a part of non-verbal reasoning.
