‘Classification’ means- Sorting the elements given in a group category or classes based on common properties and separating the remaining words, letters or digits. The questions under it are usually based on the English alphabet, based on the properties of objects and the number of similar properties. In this type of question, a group of four or five elements is given, in which three or four elements exhibit the same qualities in one form or in some form or in relation to one another, while one is related to each other. And only one element shows different qualities from all three or four. The candidate is expected to separate the different or the foreign from the given class. It is necessary to note in this perspective that the candidate should have known all the conditions of equality which are commonly asked. To solve the questions related to classification, first try to establish an alliance between all the elements present in the options. The element that is outside the established relationship will be the same answer.
Based on the word , there are four or five words or groups of four or five words, three or four of which are similar in some way. The test takers have to choose one of these words or word groups that do not match the other word or word group. In order to solve the questions based on the word, it is very important for the examiners to be aware of general studies.
Example 1. Four of the following five are somehow identical and form a group. What is that one from that group
(a) Paddy (b) Wheat (c) Millet (d) Sesame (e) Tide
Solution: (d) All other grain crops except ‘sesame’ are there whereas mole is a oilseed crop.
Example 2. Three of the following four word groups are somehow identical and form a group. Which one is not included in that group?
(a) Madhya Pradesh-Bhopal
Solution: (c) The term ‘Maharashtra-Nagpur’ is a city in the state, rather than the capital of the second, except for the couple except the couple.
Under the letter-based group, there are four or five letter groups, three or four of which are similar in some way. The test takers have to choose one of these group groups which do not match the other letter group. The letter based on the letter does not match. To solve the questions based on the letter, it is necessary to know the numeric value of each letter in the English alphabet and the opposite numbering value.
Example 1. Four of the following five are similar in some way and they create their own group. What is the one who does not join this group?
(a) HK (b) MP (c) BD (d) TW (e) NO
Solution: (C) The second letter in all other groups except BD is three letters from the first letter.
Example 2. The three of the following four are in some way or the other, but also make a group, which one is different from that group?
(a) CX (b) VF (c) RI (d) KP
Solution: (b) In both the groups except VF, both characters are opposite letters to each other.
Under the number based , four or five numbers are given, three or four of which are similar in some way. The test takers have to choose one of these numbers which does not match with other numbers. Before solving the questions based on the number, the examiner must be aware of even the numbers of numbers, odd numbers, prime numbers, whole class numbers, and complete cube numbers.
Example 1. Three of the following four are somehow identical in some way. So they form a group. Who does not come in that group?
(a) 81 (b) 81 (c) 27 (d) 121
Solution: (c) 27 “excluding all other complete class numbers.
Example 2. Four of the following five types are similar in nature, so they form a group. What is the one who does not come in this group?
(a) 21 (b) 21 (c) 37 (d) 17 (e) 31
Solution: (b) 21 ‘except for all other prime numbers.
