Syllogism Questions are a common and scoring part of the Reasoning section in banking, SSC, Railway and other competitive exams. These questions involve analysing statements, checking logical relationships and identifying valid conclusions using standard rules or Venn diagrams. In this blog, we have covered basic concepts, important types, quick tricks, solved examples from recent 2026 exams and more.

What is Syllogism in Reasoning?
Syllogism is a type of logical reasoning question where you are given a set of statements and asked to determine which conclusions logically follow from them.
These questions are frequently asked in competitive exams to test a candidate’s deductive reasoning skills. Candidates need to understand the relationships between the given statements and use logic (not assumptions) to arrive at valid conclusions.
Skills Required:
- Deductive logic
- Statement interpretation
- Visual reasoning (Venn diagrams)
- Elimination technique
Why are Syllogism Questions important in Competitive Exams?
These types of questions are mainly used to assess an aspirant’s thinking and understanding skills. They are tricky, as sometimes candidates are not just asked which conclusions follow, but also which conclusions do not follow to confuse them in the exam hall. The number of questions from this topic asked in various exams is as follows:
| Exam | No. of Questions | Difficulty |
| SSC CGL / CHSL | 1-2 | Easy |
| IBPS PO / SBI PO | 2-3 | Moderate |
| RRB NTPC / Group D | 1 | Easy |
| State PSC / Police | 1-2 | Moderate |
Syllogism is a scoring topic and can be solved in under a minute with proper techniques. It is also part of Logical Reasoning in many state and national-level exams.
Terms Used in Syllogism Questions
There are various terms used in syllogism questions. The details of the terms most commonly used in the exam are as follows:
| Term | Meaning |
| Premise | A given statement (e.g., All A are B) |
| Conclusion | Deduction based on premises |
| Universal Positive | All A are B |
| Universal Negative | No A is B |
| Particular Positive | Some A are B |
| Particular Negative | Some A are not B |
| Venn Diagram | Diagrammatic tool used for visualizing logical relations |
| Complementary Pairs | Pairs like “Some A are B” and “Some A are not B” (can both be false) |

Tricks to be followed to solve Syllogism
There are various key concepts that aspirants must keep in mind while solving this topic. The details of the tricks that candidates must follow while solving syllogism questions are as follows:
| Concept | Explanation |
| Universal Statements | Begin with “All” or “No”; have broader validity |
| Particular Statements | Begin with “Some”; limited validity |
| Basic Diagrams | A → B (All A are B), A × B (No A is B), etc. |
| Immediate Conclusion | Derived without combining multiple premises |
| Mediate Conclusion | Combines two or more statements |
| Either–Or Case | Occurs when both conclusions are wrong individually but one must be true |
What are the types of Syllogism Questions in Reasoning?
Types of questions that are mostly asked in the exam are as follows:
| Type of Syllogism | Key Features | Simple Example |
| Basic / Standard Syllogism | Direct statements with definite conclusions. Answer must be 100% true. | Statement: All cats are animals. Conclusion: All cats are animals – True |
| Either–Or Syllogism | Two conclusions are given; both cannot be true together but one must be true. | Statement: Some pens are pencils. Conclusions: (1) Some pens are not pencils. (2) All pens are pencils. – Either (1) or (2) is true |
| Coded Syllogism | Uses symbols/letters to represent statements; must decode before solving. | If A # B = All A are B If A @ B = Some A are B |
| Sequential Syllogism | Multiple statements connected in a chain; conclusion follows step by step. | Statement 1: All dogs are animals. Statement 2: All animals are living beings. Conclusion: All dogs are living beings – True |
Syllogism Formulas for Reasoning
These are the logic that aspirants must apply while solving the reasoning questions, the details of the formulas are as follows:
- All A are B – Some B are A (Possibly True)
- No A is B – No B is A (Definitely True)
- Some A are B – Some B are A (Possibly True, Not Always True)
- All A are B + All B are C – All A are C
- All A are B + No B is C – No A is C

Syllogism Tricks for SSC CGL, Bank PO and Other Exams
Some of the common tricks that candidates must always use to solve syllogism questions are as follows:
- Use Venn diagrams for accuracy
- Avoid assumptions – only trust what’s given
- Eliminate invalid conclusions first
- Use “complementary pair” logic for either–or
- Revise symbol-based codes regularly
- Practice reverse testing (assume conclusion and check statements)
- Mark conclusions as True, False, or Can’t be determined
Tips to Solve Reasoning Questions
Some common terms frequently asked in reasoning syllogism questions, along with tips on understanding these terms and the process to solve questions based on them:
- Definite Conclusion Rule: If a definite conclusion is false in any of the possible diagrams, it is considered false.
- Positive and Negative Statements: If all statements are positive, then all negative conclusions will be false in definite cases, and vice versa.
- Complementary Pair “Some + No”: For this pair, the subject and predicate can be interchanged when analyzing conclusions.
- Either-Or Case Rule: If two conclusions have the same subject and predicate and form a complementary pair but only one conclusion is true, it does not form an either-or case; “Some + Some” is not valid.
- Possible Conclusion Rule: If a possible conclusion is true in any one of the possible diagrams, it is considered possibly true.
- “Only a Few” Meaning: The phrase “Only a few” indicates that both conclusions are definitely true, e.g., “Some A are B” and “Some A are not B.”
- Valid Complementary Pairs for Either-Or: In either-or cases, the valid complementary pairs are “Some + No” and “All + Some not.”
- Subject and Predicate Consistency: Both conclusions should have one of the valid complementary pairs; subject and predicate must remain the same and cannot interchange; the answer is usually “Can’t say.”
- General Rule for Candidates: Always follow these rules carefully while solving syllogism questions to improve accuracy and reduce mistakes.

FAQs
Use Venn diagrams for visual clarity, memorize standard logic rules, and practice “either or” conditions to reduce time.
Common forms include direct verbal syllogism, coded symbol-based questions, either–or conclusions, and mixed statement types.
Use Venn diagrams, avoid assumptions, eliminate false conclusions, decode symbols properly, and practice regularly to master it.
They use codes/symbols in place of statements. You must decode and apply logic accordingly.
Break them down step by step, use short-hand diagrams, and analyze one conclusion at a time for clarity and speed.
