Definition of Logical Reasoning 

INTRODUCTION:

For every competitive exam, one of the most important sections is REASONING. One can score well in competitive exams if you score well in Reasoning.

In competitive exams, the Reasoning Ability section comprises two types of questions. These two types include Logical Reasoning and Analytical Reasoning. 

LOGICAL REASONING:

Logical reasoning is one of the most important sections for various Government and Non-Government recruitment examinations. It is one of the most fundamental skills of effective thinking. It involves using a given set of facts or data to deduce other facts by reasoning logically. Logical reasoning is testing a student’s problem-solving ability or higher use of logic.

The word ‘Logical Reasoning’ is made up of two words – Logical and Reasoning.

Logical: Logical comes from the word “logic” can be defined as “The study of truths based completely on the meanings of the terms they contain”. It is the science of the principle of valid thinking.

Reasoning: Reasoning is a process of thinking during which the individual is aware of a problem and identifies, evaluates, and decides upon a solution. It simply means looking for justification.

Logical reasoning is one of the most crucial types of reasoning and uses a methodical approach to arrive at a specific conclusion.

Logic is one section where you get better only by practice. The only way to learn logical reasoning is by doing lots of problems of different kinds.

IMPORTANCE OF LOGICAL THINKING:

‘The Importance of Logical Thinking in the Workplace ‘stated that

Logical thinkers observe and analyze phenomena, reactions, and

feedback and then draw conclusions based on that input. They can

justify their strategies, actions, and decisions based on the facts they

gather.

Thus, logical reasoning is the ability to draw a reliable conclusion or make a correct inference based on the facts, assumptions, and arguments.

Logical Reasoning helps you reason through decisions and solve problems. It gives you the ability to understand what you have read and how to build upon that knowledge.

NOTE: 1. For competitive exams, one should have a stronghold on logical reasoning. 

  1. Logical Reasoning tests skills, not knowledge.

ANALYTICAL REASONING: In Analytical reasoning, some mathematical operation has to perform to get the result. The questions based on analytical reasoning test the analytical ability of a student.

Some topics of analytical reasons are statements and arguments, Statements and conclusions, Statements and assumptions etc.

ADVANTAGES OF LOGICAL REASONING

  • The best part about logical reasoning is that it does not require any learning or prior knowledge. There is no defined syllabus for logical reasoning.
  • It is one of the most scoring sections in any competitive exam.
  • Logical Reasoning does not only help in competitive exams but also amplifies logical thinking that results in the best solution for the most complex problems in real life as well.

TYPES OF LOGICAL REASONING

In verbal logical reasoning questions, the concepts and problems are expressed in words. The students are required to read and understand the given text or paragraph and accordingly choose the right answer from the given options. These types of questions assess the comprehension skills of the student.

In non-verbal logical reasoning questions, the concepts and problems are expressed in the form of figures, images, symbols, signs, alphabets, diagrams etc. and the students are required to understand them before choosing the right answer out of the given options. This type of reasoning gets closer to the mathematical format.
