Syllogism questions are a staple in competitive exams, assessing a candidate’s logical reasoning and analytical skills. Mastering these questions can give you an edge in exams such as CAT, GRE, GMAT, banking exams, and other aptitude tests. This blog will guide you through the process of solving syllogism questions efficiently.
Understanding How Crack Syllogism Questions
Syllogism is a form of deductive reasoning where a conclusion is drawn from two or more given statements (premises). These statements are usually structured in categorical forms, such as:
All A are B.
Some A are B.
No A is B.
Some A are not B.
A conclusion is considered valid only if it logically follows from the given premises.
Types of Statements in Syllogism
Before solving syllogism questions, you must understand the four standard forms of categorical statements:
Universal Affirmative (A-type): “All A are B.”
Universal Negative (E-type): “No A is B.”
Particular Affirmative (I-type): “Some A are B.”
Particular Negative (O-type): “Some A are not B.”
Approach to Solving Syllogism Questions
To solve syllogism questions accurately, follow these steps:
Step 1: Read the Statements Carefully
Carefully analyze each statement to understand the relationship between different elements.
Step 2: Identify the Type of Statements
Classify the statements into A, E, I, or O type to understand the nature of relationships between subjects and predicates.
Step 3: Use Venn Diagrams
A Venn diagram is the most effective method for solving syllogism questions. Here’s how you can use them:
Draw circles representing each subject mentioned in the statements.
Overlap or separate the circles based on the given statements.
Check the validity of conclusions by visually analyzing the diagram.
Step 4: Apply Rules of Deduction
Some key rules to keep in mind while drawing conclusions:
If both premises are affirmative, the conclusion must also be affirmative.
If one premise is negative, the conclusion must be negative.
Two particular statements (I-type and O-type) cannot lead to a definite conclusion.
A particular conclusion cannot be drawn from two universal statements unless at least one is affirmative.
Step 5: Verify the Conclusion
For each conclusion given in the question, check whether it follows logically from the Venn diagram or standard rules.
Common Mistakes to Avoid
Assuming Additional Information: Never assume facts that are not explicitly stated in the premises.
Overlapping Incorrectly: Misrepresenting relationships in the Venn diagram can lead to wrong conclusions.
Ignoring the Possibility Cases: Some conclusions might be “possible but not definite.” In such cases, do not mark them as valid conclusions.
Misinterpreting the Statements: For example, “Some A are B” does not mean “Some A are not B.”
