The word ‘Syllogism’ is also referred to ‘Logic’. Syllogism is an important section of logical reasoning and hence, a working knowledge of its rules is required on the part of the candidate. Hence, it can be expressed as the ‘Science of thought as expressed in language’. The questions based on syllogism can be solved by using Venn diagrams and some rules devised with the help of analytical ability. With this unique characteristic, this test becomes an instrument of teaching the candidates to follow the rules and work as per the instructions without an error. Here, only the basic concept and rules, which have a bearing on reasoning faculty could alone help. There are some terminology which are used in syllogism.
Venn diagrams can be drawn to simplify syllogisms. Though not a requirement, Venn diagrams can make Syllogisms very easy to solve.
