Classification

Learning Objectives

• To get aware of classification.
• Improving the general awareness for solving problems.
• Increasing the word power for solving problems.

What is Classification?

We take an element out of some given elements and the element to be taken out is different from the rest of the elements in terms of common properties, shapes, sizes, types, nature, colours, traits etc. In this way the remaining elements form a group and the element that has been taken out is not the member of that group as this single element does not possess the common quality to be possessed by rest of the elements.

Types of Classification

(a) Letter Based Classification

Such classification is based on letters of English alphabet. So many groups of letters are given in the question in which one group is different from remaining group and hence, the different group will be our answer.

Example 1:

1. Find the odd one out of the following options.

(a)                 (b)

(c)                 (d)

(e) None of these

Explanation:      It is clear, except option (c), all the other options have a consecutive order while in case of option (c), there is reverse order.

Rest of the options is incorrect because of the correctness of option (c)

Example 2:
