What Is Deductive Reasoning?

Deductive Reasoning sets off with one or more statements called premises and then applies them to a specific situation. 

In deductive reasoning questions, the conclusions are drawn based on only the information given in the question and not your own knowledge.

If a conclusion cannot be drawn from the information provided, then the conclusion does not follow. There are several types of questions that evaluate deductive reasoning ability.

The most basic form of deductive reasoning questions are syllogisms. A syllogism is a type of logical argument in which two premises share some idea and the third sentence serves as the conclusion.

Statement: All crows are loud.

A: True

B: False

C: Data Insufficient

Ans. The correct answer is “True.”

The great thing about deductive reasoning is that if the premises are true, the conclusion must be absolutely true.

Arrangements also form a lot of questions in deductive reasoning topic. In arrangements, you’re given information about the order of items/people in comparison to one another. You need to mentally arrange the items/people according to the information given and answer a question based on the arrangement.
