What is a Syllogism?
A Syllogism is a form of reasoning where a conclusion is drawn from two or more given statements. You have to determine which conclusion logically follows from the given premises. The task is to analyse the relationship between different elements and make correct deductions.
Example:
- All cats are animals.
- All animals are living beings.
Conclusion: All cats are living beings.
Types of Syllogism Questions
In this section, we are providing the types of syllogism questions along with examples to help you understand in a better way.
Traditional or Categorical Syllogism
These are statement-based questions where you need to identify valid conclusions based on universal statements like All, Some, or No.
Example:
Statements:
- All roses are flowers.
- Some flowers are red.
Conclusions: 1. Some roses are red.
2. All red things are roses.
Answer: Only conclusion 1 does not follow.
Possibility-Based Syllogism
These questions involve terms like “can be” or “possible.” In possibility-type questions, check if the conclusion may be true without contradicting any given statement. In possibility-type questions, check if the conclusion may be true without contradicting any given statement.
Example:
Statements:
- Some dogs are cats.
- All cats are animals
Conclusion: Some dogs can be animals.
Either-Or Type Syllogism
When one of the two conclusions must be true, the answer is “Either 1 or 2 follows.” For “Either–Or” cases, both conclusions must have the same subjects and predicates. Be opposite in nature (e.g., one positive and one negative).
Example:
Statements:
- Some A are B.
- Some B are not A.
Conclusions:
- All A are B.
- Some A are not B.
Answer: Either 1 or 2 follows.
Negative Syllogism
These involve negative statements such as No, None, or Some not. Always handle negative words carefully and verify their logical consistency.
Example:
Statements:
- No book is a pen.
- All pens are pencils.
Conclusion: No book is a pencil.
Tips to Solve Syllogism Questions in RRB PO Exams
In this section, we are giving tips to solve syllogism questions in RRB PO Exams. Use these tips to solve syllogism questions accurately and in less time as well.
Use Venn Diagrams to solve syllogisms accurately
The Venn Diagram method is the fastest and most reliable way to check the conclusions of syllogism statements. You will visually represent each statement as a circle to view the logical associations between different terms. Venn Diagrams reduce the chances of mistakes whenever students are making interpretations of statements. You can see several conclusions at one time. They are also helpful with possible and negative cases where mental constructions can go wrong.
For instance, “All cats are animals” means you would draw a circle to reflect cats that is totally contained in a larger circle for animals. This clearly indicates that every cat is an animal, but not every animal is a cat.
Memorise Key Rules to get solutions faster
Here are some basic key rules to get solutions faster that can save time in the examination, which ultimately leads to better scores. By mentally applying these conversions, you can eliminate incorrect answers without drawing any conclusions. Here are some conversions you will find useful:
- All A are B → Some B are A (Always True)
- Some A are B → Some B are A (Always True)
- No A is B → No B is A (Always True)
Eliminate Impossible Options
Rather than checking each conclusion individually, you should learn to assess contradictions at a glance. You can put a conclusion in an instant “false” category if a conclusion outright violates one of the given statements.
Let’s say one of the statements is “No dogs are cats” and a conclusion is “Some dogs are cats”. Boom, you can throw the conclusion out without thinking about it. This process of elimination will save you special seconds while remaining focused on the logical reasoning for the trickier statements.
Practice Mixed Question Sets
Sometimes, you can face questions that contain traditional syllogism statements along with Syllogism based on possibility and negative Syllogism questions together in the same passage. In such a situation, we recommend practising mixed question sets regularly to build your comfort and fluency in switching question types.
