How Syllogism Appears in SSC CGL
Syllogism is part of the General Intelligence & Reasoning section (25% of the SSC CGL syllabus). See the full SSC CGL Tier-I breakdown.
Syllogism Solved Examples for SSC CGL
12 exam-pattern syllogism questions from the practice bank, each with a full solution.
Statements: Some teachers are doctors. All doctors are engineers. Conclusions: I. Some engineers are teachers. II. All teachers are engineers. Choose the correct conclusion.
- A.Only conclusion I followsCorrect
- B.Only conclusion II follows
- C.Both I and II follow
- D.Neither I nor II follows
Solution
From the statements, 'Some teachers are doctors' and 'All doctors are engineers', it logically follows that some teachers are engineers (conclusion I). However, we cannot conclude that all teachers are engineers (conclusion II).
Statements: Some cars are not bikes. All scooters are bikes. Conclusions: I. Some cars are not scooters. II. No scooter is a car.
- A.Only conclusion I followsCorrect
- B.Only conclusion II follows
- C.Both conclusions I and II follow
- D.Neither conclusion I nor II follows
Solution
Since some cars are not bikes and all scooters are bikes, it follows that some cars are not scooters. However, we cannot definitively conclude that no scooter is a car, as some cars might still be scooters. Only conclusion I follows.
Statements: All apples are bananas. All bananas are oranges. Some oranges are grapes. All grapes are mangoes. Conclusions: I. Some mangoes are oranges. II. All apples are oranges. III. Some grapes are bananas. IV. All mangoes are apples.
- A.Only I and II followCorrect
- B.Only II and III follow
- C.Only I, II and III follow
- D.Only I and IV follow
Solution
Given: All apples are bananas, All bananas are oranges, Some oranges are grapes, All grapes are mangoes. I. 'Some mangoes are oranges' - True. All grapes are mangoes, and some oranges are grapes, so some mangoes are oranges. II. 'All apples are oranges' - True. All apples are bananas, and all bananas are oranges, so all apples are oranges. III. 'Some grapes are bananas' - Not necessarily true. Only some oranges are grapes, but we can't conclude that some grapes are bananas. IV. 'All mangoes are apples' - Not necessarily true. All grapes are mangoes, but there's no link to suggest all mangoes are apples.
Three statements are given followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: No card is a parcel. All cards are envelopes. Some envelopes are bags. Conclusions: I. All envelopes can never be parcels. II. No card is a bag. III. At least some bags are postcards.
- A.Only I followsCorrect
- B.Only II follows
- C.Only I and III follow
- D.Only II and III follow
Solution
From the statements, only conclusion I logically follows. All envelopes can never be parcels.
Two statements are given below and then conclusions I, II and III are given. Assuming the statement to be true, even if it seems to be at variance from commonly known facts, you have to decide which of the given conclusions logically follows the given statements. Statement: Some cars are vehicles. No vehicle is four wheeler. Conclusion: I. There are no cars that are four wheeler. II. All four wheelers are cars. III. Some vehicles are cars.
- A.Only conclusion I follows.
- B.Both conclusions I and II follow.
- C.Only conclusion II follows.
- D.Only conclusion III follows.Correct
Solution
From the statements, only conclusion III (Some vehicles are cars) logically follows.
Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: All cards are boxes. All boxes are torches. All torches are shoes. Conclusions: I. All shoes are torches. II. All torches are boxes. III. All boxes are cards. IV. All cards are shoes
- A.Only conclusion IV followsCorrect
- B.Only conclusions II and III follow
- C.Only conclusions I and II follow
- D.Only conclusion III follows
Solution
From the statements, only the conclusion 'All cards are shoes' logically follows.
In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: I. All W are S. II. No D is W. Conclusion: I. Some S are W. II. All S are D. III. No W is D
- A.Only conclusion III follows
- B.Both conclusions I and III followsCorrect
- C.Both conclusions I and II follows
- D.All conclusion follows
Solution
From the statements, 'Some S are W' and 'No W is D' logically follow.
Conclusions: I. All actors are dancers. II. Some dancers are singers. Which of the following sets of statements could lead to these conclusions?
- A.Statements: All actors are singers. All singers are dancers.
- B.Statements: All actors are dancers. Some dancers are singers.Correct
- C.Statements: Some actors are dancers. All dancers are singers.
- D.Statements: Some actors are singers. Some singers are dancers.
Solution
Conclusion I requires 'actors' to be fully contained within 'dancers'. Conclusion II requires some overlap between 'dancers' and 'singers'. Option 2 directly supports this. If all actors are dancers, and some dancers are singers, then both conclusions are valid.
Statements: All pencils are pens. No pen is a rubber. (SSC Neg Syl 2) Conclusions: I. No pencil is a rubber. II. Some pens are pencils.
- A.Both conclusions I and II followCorrect
- B.Only conclusion I follows
- C.Only conclusion II follows
- D.Neither follows
Solution
Since all pencils are inside pens, and pens and rubbers are mutually disjoint, No pencil is a rubber (true) and Some pens are pencils (true).
Based on the logical principles of Definite Conclusions, determine the valid outcome or relationship.
- A.Conclusion I follows logically from the given premiseCorrect
- B.Conclusion II follows logically from the given premise
- C.Neither Conclusion I nor Conclusion II follows
- D.Both Conclusion I and Conclusion II follow logically
Solution
In Definite Conclusions, analyzing the relationship between the terms verifies that Conclusion I is a direct and necessary deduction.
Statements: Some fruits are vegetables. No vegetable is a sweet. Conclusions: I. Some fruits are not sweets. II. All sweets are fruits. Choose the correct conclusion.
- A.Only conclusion I followsCorrect
- B.Only conclusion II follows
- C.Both I and II follow
- D.Neither I nor II follows
Solution
Since some fruits are vegetables and no vegetable is a sweet, it logically follows that some fruits are not sweets. The reverse relationship (all sweets are fruits) cannot be derived. Therefore, only conclusion I follows.
Statements: All fish are aquatic. No aquatic is a bird. (SSC Poss Neg 3) Conclusions: I. Some fish being birds is a possibility. II. Some aquatic are fish.
- A.Only conclusion II followsCorrect
- B.Only conclusion I follows
- C.Both conclusions I and II follow
- D.Neither follows
Solution
Since fish are aquatic and aquatic cannot be birds, fish cannot be birds. Conclusion I is false. Conclusion II is definitely true.
Syllogism — Frequently Asked Questions
What is the fastest method for syllogism questions?
Venn diagrams — draw the minimal diagram the statements force, and test each conclusion against it. For "possibility" conclusions, ask instead whether ANY valid diagram allows it.
When does an either-or answer apply?
When two conclusions are individually not certain but form a complementary pair — same subject and predicate, covering all cases between them (e.g. "some" + "no"). Then "either I or II follows".
