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
Complete Overlap Relation: If one item belongs to the class of the second and the second belongs to the class of third, then the representation is in the form of three concentric circles, as shown in fig.
Ex. Seconds, Minutes, Hours
Clearly, seconds are a part of minutes and minutes are a part of hours. So, the Venn diagram would be as shown in the adjoining figure with circle A representing Seconds, circle B representing Minutes and circle C representing.
