Disjoint And Overlap 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. We will be  a few different types of Venn diagrams with their implications made clear. Suppose you are given a group of three items.

Disjoint and Overlap Relation: If two separate items belong to the class of the third, they are represented by two disjoint circles inside a bigger circle as shown in fig.

Ex. Table, Chair, Furniture

Clearly, table and chair are separate items of furniture. So, they would be represented as in the adjoining figure with circle A representing Table, circle B representing Chair and circle C representing Furniture.

Bus, Car, Vehicle.
