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

All erasers are stationery items.
Conclusions:
I. No pencils are stationery items.
II. Some stationery items are erasers.
A. Only I follows

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.
