SBI PO Mains Syllogism Quiz 2026:10 High-Level Questions

Test your conceptual accuracy with these 10 exam-level Mains questions featuring Coded, Reverse, and Column-Based patterns. (Detailed solutions and answer keys are provided at the end of the article).

Directions (Q1–Q10) Read the statements and conclusions carefully and select the logically valid option. Each correct response carries +2 marks, while each incorrect response carries −0.5 marks.

Q1. Coded Syllogism — Statements: P # Q, Q @ R, R % S, S # T. Here @ = All, # = Some, % = No, $ = Some are not, and ! indicates possibility. Conclusions: I. P ! % S II. R $ T

Correct Answer: A) Only conclusion I follows
Explanation: Some P are Q, all Q are R, and no R is S. Therefore, at least some P are definitely not S, and it is possible that no P is S; Conclusion I follows. Nothing guarantees that some R are not T, so Conclusion II does not follow.

Q2. Reverse Syllogism — Conclusions: I. Some Cats can never be Dogs. II. All Lions being Tigers is a possibility. Which statement set makes both conclusions true?

Correct Answer: C) Some Cats are Tigers; All Tigers are Lions; No Lion is a Dog
Explanation: In Option C, some Cats are Tigers, all Tigers are Lions, and no Lion is a Dog. Thus some Cats are definitely not Dogs. Also, there is no negative restriction preventing all Lions from being Tigers, so that possibility remains valid.

Q3. Statements: Only a few Sodas are Juices; All Juices are Limes; No Juice is a Coke. Conclusions: I. Some [P] being not [Q] is a possibility. II. Some [Q] are not [R]. Which substitution makes both conclusions logically follow?

Correct Answer: E) None of these
Explanation: Option A does not guarantee 'Some Cokes are not Sodas.' Option B contradicts 'All Juices are Limes' because it requires some Juices not to be Limes. Option C does not guarantee that some Juices are not Sodas. Therefore, none of the combinations makes both conclusions follow.

Q4. Statements: All pens are books; Some books are files; No file is a paper; Some papers are documents. Conclusions: I. Some books are not papers. II. No pen is a file. III. Some documents are not files.

Correct Answer: B) Only I and III follow
Explanation: Some books are files and no file is paper, so some books are not papers: I follows. Nothing forbids pens from being files, so II does not follow. Some papers are documents and no paper can be a file, so some documents are not files: III follows.

Q5. Statements: Some managers are officers; All officers are employees; No employee is a trainee; Some trainees are interns. Conclusions: I. Some managers are employees. II. No officer is a trainee. III. Some interns are not employees.

Correct Answer: D) All I, II and III follow
Explanation: Some managers are officers and all officers are employees, so I follows. Since no employee is a trainee, no officer can be a trainee, so II follows. Some trainees are interns, and trainees cannot be employees, so some interns are not employees: III follows.

Q6. Statements: All laptops are devices; Some devices are tablets; No tablet is a mobile; Some mobiles are gadgets. Conclusions: I. Some gadgets are not tablets. II. No laptop is a mobile. III. Some devices are not mobiles.

Correct Answer: B) Only I and III follow
Explanation: Some mobiles are gadgets, and no mobile can be a tablet; therefore some gadgets are not tablets: I follows. No relation rules out laptops being mobiles, so II does not follow. Some devices are tablets, and no tablet is mobile; therefore some devices are not mobiles: III follows.

Q7. Statements: Some teachers are writers; All writers are researchers; Some researchers are scientists; No scientist is a teacher. Conclusions: I. Some writers are not scientists. II. Some teachers are researchers. III. No writer is a teacher.

Correct Answer: A) Only I and II follow
Explanation: Some teachers are writers. Since no teacher can be a scientist, those teacher-writers are writers who are not scientists: I follows. All writers are researchers, so those teachers are researchers: II follows. III contradicts the statement that some teachers are writers.

Q8. Statements: All chairs are furniture; No furniture is plastic; Some plastic items are boxes; Some boxes are chairs. Conclusions: I. Some boxes are not plastic. II. Some chairs are not plastic. III. No box is furniture.

Correct Answer: C) Only I and II follow
Explanation: Some boxes are chairs. All chairs are furniture, and no furniture is plastic. Hence those boxes are not plastic: I follows, and those chairs are not plastic: II follows. III is false because some boxes are chairs and therefore furniture.

Q9. Statements: Some doctors are professors; All professors are scholars; No scholar is an artist; Some artists are musicians. Conclusions: I. Some doctors are scholars. II. Some musicians are not scholars. III. No professor is an artist.

Correct Answer: D) All I, II and III follow
Explanation: Some doctors are professors and all professors are scholars, so I follows. Some artists are musicians and no artist can be a scholar, so some musicians are not scholars: II follows. Since all professors are scholars and no scholar is an artist, no professor is an artist: III follows.

Q10. Statements: All trains are vehicles; Some vehicles are buses; No bus is a truck; Some trucks are machines. Conclusions: I. Some machines are not buses. II. Some vehicles are not trucks. III. No train is a truck.

Correct Answer: A) Only I and II follow
Explanation: Some trucks are machines, and no truck can be a bus, so some machines are not buses: I follows. Some vehicles are buses, and no bus is a truck, so some vehicles are not trucks: II follows. No negative relation is given between trains and trucks, so III does not follow.

Core Concepts and Rules for SBI PO Mains Syllogism

To consistently solve Mains-level syllogism questions without relying on guesswork, candidates must master five pivotal conceptual rules:

1. “Only a few A are B” Condition

This is a dual statement combining a positive and a negative relation simultaneously:

Definite Truth 1: Some A are B.
Definite Truth 2: Some A are NOT B.
Possibility Rule: “All A being B is a possibility” is ALWAYS FALSE. However, “All B being A is a possibility” CAN BE TRUE unless blocked by other constraints.

2. “Only A is B” Condition

This statement converts to an exclusive universal relationship: “All B are A” with a strict restriction. Element B becomes completely locked inside A and CANNOT intersect with any other third element C, D, or E under any circumstances.

3. Restatement Rule (“Re-Statement is Not a Valid Conclusion”)

In standard banking syllogism logic, a conclusion must be a derived deduction obtained by combining premises. If a conclusion simply repeats one of the given statement premises word-for-word, it is treated as non-following / invalid because no new logical insight was derived.

4. Possibility Cases vs Definite Certainty

A possibility conclusion (e.g., “All X being Y is a possibility”) is TRUE if there exists at least one valid Venn diagram configuration where X lies inside Y without violating any statement. However, if a condition is already definitely true or definitely false in logic, stating it as a mere possibility makes the conclusion invalid.

5. Complementary Pairs (“Either-Or” Rules)

An “Either I or II follows” relation requires three strict criteria:

Both individual conclusions must be uncertain/unproven (does not follow individually).
They must share the exact same subject and predicate elements.
They must form a valid complementary pair: (Some + No) or (All + Some Not).

Comparison of Key SBI PO Mains Syllogism Patterns

Pattern Type	Question Structure	Key Solving Technique
Reverse Syllogism	Conclusions are given in the question stem; statements are in options.	Eliminate options quickly by testing negative constraints and exclusive relations first.
Coded Syllogism	Relations are replaced with symbols (@, #, %, $).	Decode symbols into standard logical form before drawing minimum overlapping diagrams.
Fill-in-the-Blanks	Statements or conclusions contain empty brackets [P], [Q], [R].	Substitute option pairs systematically into variables to check validity.
Conditional / Only A is B	Features restricted inclusion/exclusion operators.	Treat “Only A is B” as “All B are A” and isolate B from all other categories.

Benefits of Solving SBI PO Mains Syllogism Practice Sets & Quizzes

Speed in Pattern Recognition: Practicing coded and Reverse syllogisms reduces decoding time from 3 minutes per question down to under 60 seconds.
Elimination of Negative Marking: SBI PO Mains penalizes wrong answers by 0.25 marks. Understanding “Only a few” nuances prevents common trap errors.
High Scoring Yield: Syllogisms account for 4 to 6 marks in the Reasoning section. A strong command over these concepts guarantees high-accuracy marks.
Enhanced Structural Deduction: Mastering multi-statement linkage improves performance across critical reasoning and analytical puzzles.

Conclusion

Mastering Syllogism for SBI PO Mains requires moving beyond standard Prelims diagrams and building high precision in non-traditional formats like Reverse, Coded, and restricted conditional statements. By understanding key rules such as “Only a few”, exclusive “Only”, and statement restatement invalidity, candidates can easily secure full marks in the Reasoning Ability section. Utilize the practice questions and detailed explanations provided above to sharpen your conceptual accuracy and elevate your SBI PO Mains 2026 score.

Syllogism Questions for SBI PO Mains Frequently Asked Questions

Q1. Is a restatement considered a valid conclusion in SBI PO Mains Syllogism?

No. In banking syllogism logic, a conclusion must be a fresh derivation obtained by combining statement premises. If a conclusion simply repeats a statement premise verbatim, it does not qualify as a valid logical conclusion.

Q2. What is the difference between “Few A are B” and “Only a few A are B”?

“Few A are B” means “Some A are B”. On the other hand, “Only a few A are B” is a dual condition meaning both “Some A are B” AND “Some A are NOT B” are definitely true simultaneously.

Q3. How do I solve Coded Syllogism questions quickly during the exam?

First, create a quick reference key decoding each symbol into its basic form (@ = All, # = Some, % = No, $ = Some Not). Then convert the statement chain into minimum overlapping diagrams to evaluate conclusions rapidly.

Q4. How does “Only A is B” affect relations with other elements?

“Only A is B” means “All B are A”, but with a strict exclusion: element B is locked strictly inside A and can NEVER overlap with any third element (C, D, etc.).

Q5. Where can I find more SBI PO Mains reasoning practice material and sectional tests?

You can practice specialized sectional mock tests and downloadable PDFs on trusted banking preparation platforms including Oliveboard, Smartkeeda, Testbook, and PracticeMock.
