Sample Questions – Syllogism

Syllogism questions evaluate logical reasoning, analytical thinking, deduction ability, and understanding of relationships between different groups. These questions are highly scoring in competitive exams when solved using proper logic and Venn diagram techniques.

Below are important exam-oriented sample questions with detailed explanations and logical analysis.

Sample Question 1 – Universal Statement

Statements:

All pens are books.
All books are bags.

Conclusions:

I. All pens are bags.
II. Some bags are pens.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: C

Explanation:

Since all pens are books and all books are bags, pens must also belong to bags.

Pens → Books → Bags

Therefore:

  • All pens are bags.
  • Some bags are pens.

Sample Question 2 – Negative Statement

Statements:

No cats are dogs.
All dogs are animals.

Conclusions:

I. No cats are animals.
II. Some animals are dogs.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: B

Explanation:

The first conclusion does not follow because cats may or may not be animals.

However, since all dogs are animals, some animals are definitely dogs.

Sample Question 3 – Some Statement

Statements:

Some flowers are roses.
All roses are beautiful.

Conclusions:

I. Some flowers are beautiful.
II. All flowers are beautiful.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: A

Explanation:

Since some flowers are roses and all roses are beautiful, some flowers are definitely beautiful.

But not all flowers are necessarily beautiful.

Sample Question 4 – Two Particular Statements

Statements:

Some students are singers.
Some singers are dancers.

Conclusions:

I. Some students are dancers.
II. Some dancers are students.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: D

Explanation:

Two particular statements do not guarantee a definite connection between students and dancers.

Sample Question 5 – Complementary Pair

Statements:

Some cars are bikes.

Conclusions:

I. Some cars are bikes.
II. No cars are bikes.

A. Only I follows
B. Only II follows
C. Either I or II follows
D. Neither follows

Correct Answer: A

Explanation:

The statement directly confirms that some cars are bikes.

Therefore, Conclusion I follows and Conclusion II is false.

Sample Question 6 – Possibility Case

Statement:

Some teachers are writers.

Question:

Is “All teachers being writers” a possibility?

A. Yes
B. No

Correct Answer: A

Explanation:

The statement does not restrict all teachers from being writers. Therefore, the possibility is valid.

Sample Question 7 – Chain Logic

Statements:

All apples are fruits.
All fruits are healthy items.

Conclusions:

I. All apples are healthy items.
II. Some healthy items are apples.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: C

Explanation:

Apples → Fruits → Healthy Items

Both conclusions logically follow.

Sample Question 8 – Negative Conclusion

Statements:

No pencils are erasers.
All erasers are stationery items.

Conclusions:

I. No pencils are stationery items.
II. Some stationery items are erasers.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: B

Explanation:

The first conclusion is not definite because pencils may still be stationery items.

Since all erasers are stationery items, some stationery items are erasers.

Sample Question 9 – Conversion Logic

Statement:

All doctors are educated.

Which conclusion is valid?

A. All educated are doctors.
B. Some educated are doctors.
C. No educated are doctors.
D. Some doctors are not educated.

Correct Answer: B

Explanation:

From “All doctors are educated,” the valid conversion is:

Some educated are doctors.

Sample Question 10 – Mixed Statements

Statements:

All lions are animals.
Some animals are wild.

Conclusions:

I. Some lions are wild.
II. Some wild are animals.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: B

Explanation:

There is no guaranteed connection between lions and wild animals.

However, “Some animals are wild” can be converted into:

Some wild are animals.

Sample Question 11 – Either-Or Logic

Statements:

All pens are books.

Conclusions:

I. Some pens are books.
II. No pens are books.

A. Only I follows
B. Only II follows
C. Either I or II follows
D. Neither follows

Correct Answer: A

Explanation:

“All pens are books” guarantees that some pens are books.

Therefore, Conclusion I follows directly.

Sample Question 12 – Universal Negative

Statements:

No birds are mammals.
All mammals are animals.

Conclusions:

I. No birds are animals.
II. Some animals are mammals.

A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows

Correct Answer: B

Explanation:

Birds may still be animals, so Conclusion I is invalid.

Since all mammals are animals, some animals are mammals.

Sample Question 13 – Flow Diagram Logic

Teachers → Educated → Respected

Statements:

All teachers are educated.
All educated people are respected.

Conclusion:

All teachers are respected.

Correct Answer: Valid Conclusion

Explanation:

This follows direct chain deduction logic.

Sample Question 14 – Particular Negative
