Intersecting And Disjoint Relation

Logical Venn Diagrams: This section deals with questions which aim at analysing a candidates ability to relate a certain given group of items and illustrate it diagrammatically. Here are a few different types of Venn diagrams with their implications made clear.

Suppose you are given a group of three items. Then

Intersecting And Disjoint Relation. If two items are partially related to each other so are represented by two intersecting circles and the third item is entirely different from the two, so is represented by a disjoint circle. The relation is represented as shown alongside.

Ex. Professor, Author, Children

Clearly, some professors can be authors and vice versa. This would be represented by two intersecting circles. But the class of children would be entirely different from these two. Thus, the venn diagram would be as shown in fig. with Circle A representing Professors, Circle B representing Authors and circle C representing Children.
