<h2 id="content-id-5554-0">What is Classification in Reasoning?</h2>

Classification refers to arrangement of groups of people or things, by class or category and find out the odd one among them, which differs from the others having some common logic. Classification is categorized into three types:

A) Letter Based Classification

B) Number Based Classification

C) General Knowledge and Meaning Based Classification

<h2 id="content-id-5554-1">Letter Based Classification</h2>

In this type of Classification, group of letters and words is given in options. Certain relationship or property is being followed by these letters.

Example: Three of the four are alike in a certain way, which of the following does not belong to the group.

1.EV  2.KP  3.GT  4.RV

Solution: (4) RV 
The pattern which follows here is: Opposite of letters is given except in Option D. 
Opposite of R is I not V.

<h2 id="content-id-5554-2">Number Based Classification</h2>

In this type of Classification, group of numbers and digits is given in the options. Certain relationship or property is being followed among these numbers.
