Syllogisms :
Syllogisms can be defined as a deductive scheme under which a formal argument is made. It consists of major and minor premises, leading up to a conclusion.
For example, let us look at the following example:
Major Premise: Every crime is deplorable;
Eve teasing is a crime;
Conclusion: Eve teasing is deplorable.
Questions based on Syllogisms always first state the premises and then ask you to derive the conclusion on the basis of the relationship existing between the different elements of the premises.
The best method for solving Syllogisms involves the use of Venn Diagrams.
Premises - Various Patterns
A premise is defined as proposition antecedently supposed or proved as a basis of argument or interference. In other words: something assumed or taken for granted.
Statements Premises if the items evidently belong to three groups, the Venn diagram representing it would be as shown alongside. |
|
If one item belongs to the class of the second and the second belongs to the class of third. |
|
If two separate item belong to the class of the third they are represented by two disjoint circle inside a bigger circle. |
|
If two item belong to the class of the third such that some items of each of these two groups are common in relationship, then they are represented by two intersecting circles enclosed within a bigger circle. |
|
If two items are partly related to third, and are themselves independent of each other |
|
If the three items are partly related to each other, they are represented as |
|
If one item belongs to the class of second while third item is entirely different from the two, then they may be represented by |

If one belongs to the class of second and third item is partly related to the second, they are represented as |
