Syllogism Meaning – Types, Tricks, Questions, Solved Examples and Reasoning

Syllogism means making a conclusion or judgment. It’s an important part of logical reasoning and appears in almost all competitive exams like SSC, Railway, Defence, Banking, and Teaching. Syllogism questions can help you score well in the Reasoning section with less practice and effort. You just need basic knowledge and a few tricks to answer these questions accurately. This article will explain what syllogism is, its types, some useful tricks, and the types of questions you might face in exams.

What is Syllogism?

Syllogism can be referred to as an instance of form of reasoning that comes under logical reasoning. This form of reasoning includes statements, conclusions, and then with the help of venn diagrams, the candidates can draw their answers. These statements or conclusions do not need to be true in the real world.
Example: All Cats are animals, all animals have four legs, so, all cats have four legs.

Types of Syllogism in Reasoning

In Reasoning syllogism is of basically four types which are as follows:

• Fundamental Syllogism – In this type of syllogism reasoning, the conclusions must be 100% true always. The conclusions which are 99% true will be considered False.
• Either OR Case Syllogism – In this type of syllogism in reasoning, when the conclusions are not 100% true but the two given conclusions are 50% true then the either-or case will be formed. In it, both the statements should have the same elements necessarily.
• Coded Syllogism – In the coded type of syllogism, statements and conclusions are given in the coded form. Candidates need to decode the statements and conclusions to find the answer.
• Sequential Syllogism – In the sequential type of syllogism, statements are given followed by the options. Candidates need to choose the set in which the third statement can be logically deduced from the first two statements.

Syllogism Reasoning

Syllogism means to find a conclusion based on the given conditions or instructions. Syllogism is a part of logical reasoning.
