Syllogism Tricks, Examples and Questions

Facts for Syllogism: Syllogism is a word which everybody has heard of or even had to use in practice. This modern form of logical reasoning is almost always associated with aptitude tests and assessment training nowadays. But what is the origin of this word, what does syllogisms mean and more important how to solve it?

Solving Method for Syllogisms
Syllogism can be solved in many ways, however the most frequently used method is by using the so called Venn diagrams. Venn diagrams show all possible and hypothetically logical relations between a collection of finite and infinite statements. By means of an overlap between some certain assumptions conclusions can be made using the (in)finite statements. Next a few syllogism examples will follow in which words will be classified and the syllogism will be checked on validity.

Solved Questions For Syllogism

Example: 1. All Canadians are right handed
2. All right handed are opticians
3. Conclusion: Some opticians are Canadian
Solution :To check the validity of this statement first the different terms are appointed.
Subject: Optician
Predicate: Canadian
Middle term: Right handed

Since the two premises (a and b) from the example are valid, the conclusion must be valid two, since it is not possible for the premises to be true and the conclusion to be false.

Example 2:
All mortals die
All men are mortals
Conclusion: All men die

Syllogisms-Types and Examples

1. Conditional syllogisms :Conditional syllogisms are better known as hypothetical syllogisms, because the arguments used here are not always valid. The basic of this syllogism type is: if A is true then B is true as well.

Example 3: Major premise: If Johnny is eating sweets every day, he is placing himself at risk for diabetes.
Minor premise: Johnny does not eat sweats everyday
Conclusion:Therefore Johnny is not placing himself at risk for diabetes
Solution :
This conclusion is invalid because it is possible that Johnny does not eat sweats every day but does eats cake every day what also puts him at risk for diabetes.

2. Disjunctive syllogisms : These syllogism types do not actually state that a certain premise (major or minor) is correct, but is does states that one of the premises is correct. The basic type for this syllogism is: Either A or B is true, but they can’t be true at the same time.

Example 4:
Major premise: Either the meeting is at school or at home.
Minor premise: The meeting is not at home.
Conclusion:Therefore the meeting is at school.
Solution :
The conclusion of the syllogism type may be given, however most of the times the conclusion can be drawn based up on own conclusions.
