Overlap And Complete Intersection Relation
Overlap And Complete Intersection 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 Complete Intersection Relation: If one item belongs to the class of second so they are represented by concentric circles and the third item is partly related to these two, they are represented by an intersecting circle as shown alongside.
Ex. Females, Mothers, Doctors
Clearly, all mothers are females. This would be represented by two concentric circles. But, some females and some mothers can be doctors. So, the circle representing doctors would intersect each of the two concentric circles. Thus, the diagram becomes as shown in fig. with circle A representing Mothers, circle B representing Females ad circle C representing Doctors.
Illustration: Identify the option which shows the relation between
Pen, Ink, Black.
A. | B. | . C. |
D. |
Answer: D
Solution: We know that, All pens have Ink hence they are represented by concentric circles, but some pens can have black ink as well as some inks are blacks so they are represented by an intersecting circle. Hence the correct option is D
