Overlap And Disjoint Relation
Overlap 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
Overlap And Disjoint Relation: If one item belongs to the class of second while third item is entirely different from the two, then first are represented by concentric circle and the third by disjoint circle as shown in the adjoining diagram.
Ex. Engineers, Human Beings, Rats
Clearly, all engineers are human beings. This would be represented by two concentric circles. But the class of rats is entirely different from these two. Thus, these items would be represented as shown in fig. with circle A representing Engineers, circle B representing Human Beings and circle C representing Rats.
Illustration: Identify the option which shows the relation between
Judge, Criminal, Thief.
A. | B. | . C. |
D. |
Answer: A
Solution: We know that, all thieves are criminals hence they are represented by concentric circles, but judges can neither be thief nor criminal so is represented by a disjoint circle. Hence the correct option is A

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
