Basics and Rules in Syllogism Questions to Solve Quickly
Introduction to Syllogism QuestionsÂ
Syllogism Questions to Solve Quickly you need to understand the concept behind syllogism questions. Syllogism is a form of reasoning, in this we need to draw conclusions from the given assumed statements, maybe not real.
From the given statements we need to draw Venn diagram and from this diagram compare those given conclusions and conclude the given conclusion either followed or not to the Venn diagram.
If the conclusion is valid to the diagram, then it follows otherwise conclusion is invalid and not follows. This is the meaning of syllogism.
Basics of syllogism questions for easy understand
Basic Concepts related to Positive Statements in Syllogism Questions
Basic Concept 1: Some A is B (Positive Statement)-Syllogism Questions
Basic Concept 2: All A is B ( Positive Statement)-Syllogism Questions
Basic Concept 3: Some A is B; Some B is C ( Two Positive Statements)-Syllogism Questions
“Some B is C”
 Basic Concept 4: All A is B; All B is C (Two Positive Statements)-Syllogism Questions
Some C is A.
Basic Concept 4: Some A is B; All B is C. (Two Positive Statements)-Syllogism Questions
Possible Conclusions are drawn between A and C
Some A is C
Some C is A
Basic Concept 5: All A is B;Â Some B is C. (Two Positive Statements)-Syllogism Questions
Basic Concept 6: All B is A; All C is A. (Two Positive Statements)-Syllogism Questions
Basic Concepts related to Negative Statements (indicated with X )-Syllogism Questions
Basic Concept 1: No A is B. (Negative Statement)-Syllogism Questions
Basic Concept 2: All A is B; No B is C. ( Positive and Negative Statements)-Syllogism Questions
Basic Concept 3: All A is B;Â No A is C. (Positive and Negative Statements)-Syllogism Questions
Venn diagram for this positive and negative statement.
Possible Conclusions are drawn between A and B
Basic Concept 4: Some A is B; No B is C. (Positive and Negative Statements)-Syllogism Questions
Basic Concept 5: Some A is B; No A is C (Positive and Negative Statements)-Syllogism Questions
Concepts related to Complementary Pairs (Given Conclusions not follows the Venn Diagram)
Syllogism Questions-Explanation of Syllogism in Complementary Pairs – ” Either or“
Syllogism Questions-Concept-related to Possibility Case of Conclusions ( can be in conclusion )
In this concept, we need to draw two Venn diagrams.
1) Basic Diagram – According to given statements
2) Possibility Diagram – No given in statements, but may be possible to draw.
Here we need to compare “No” type of conclusion and “Possible” type of conclusion.
Note: Rules for Possibility Conclusions-Syllogism Questions
- If the “No” type of conclusion is false in anyone diagram (Basic or Possibility), then ” No type of conclusion has not followed the diagram.
- But here if “Possible” type of conclusion is true in anyone diagram (Basic or Possibility), then “Possible” type of conclusion has followed the diagram.
- If “Possible” type of conclusion is true in both diagrams (Basic and Possibility), then “Possible” type of conclusion has followed the diagram.
- If “Possible” type of conclusion is false in both diagrams (Basic and Possibility), then “Possible” type of conclusion has not followed the diagram.
- If all the parameters or statements in single Venn diagram, then “No” type of conclusion will be not followed.
Example Venn diagram:
Example 1:
Venn DiagramÂ
(II) Possibility Diagram – 1
- See the basic diagram above, there is no relation between trucks and cars. So the basic diagram not obeys the conclusion 1.
- See the possible diagrams 1 and 2, there is a relation between cars and trucks. but no relation trucks and jeeps, hence we are not violating the statement of No Jeep is Truck. So the possible diagrams obey the conclusion1.
- Finally, the conclusion 1 even not obeys by the basic diagram, the possible diagrams obeys. So the conclusion 1 must follow.
- See the basic diagram above, there is no relation between trucks and cars. So the basic diagram not obeys the conclusion 2.
- See the possible diagrams 1, there is a relation between cars and trucks as All Trucks are Cars. but no relation trucks and jeeps, hence we are not violating the statement of No Jeep is Truck. So the possible diagrams obey the conclusion1.
- Finally, the conclusion 2 even not obeys by the basic diagram, the possible diagram 2 obeys. So the conclusion 2 must follow.
