Logical Reasoning for Bank Exams
Syllogism + Inequalities Mastery (Professional Level)
Syllogism and Inequalities are rule-based reasoning topics. These are easy scoring if rules are clearly understood.
1. Syllogism (Concept)
Statements and conclusions are given. You must identify which conclusions logically follow.
- All A are B
- Some A are B
- No A is B
- Some A are not B
2. Syllogism Rules
- All + All → All (possible)
- All + Some → Some
- Some + Some → No definite conclusion
- No + All → Some not
3. Venn Diagram Method
Use diagrams to visualize relationships.
Best method for solving quickly
4. Inequalities (Concept)
Compare values using symbols.
- > Greater than
- < Less than
- = Equal
- ≥ Greater or equal
- ≤ Less or equal
5. Chain Logic
A > B and B > C → A > C
Same direction → definite conclusion Different direction → no conclusion
6. Shortcut Tricks
- Use Venn diagrams for syllogism
- Follow chain method in inequalities
- Check direction carefully
- Avoid assumptions
7. Advanced Strategy
Identify pattern quickly and apply rules directly.
Avoid drawing complex diagrams for simple cases.
Speed Strategy
- Memorize rules
- Apply direct logic
- Avoid guesswork
- Practice regularly
Practice Questions
1. All A are B, All B are C → A ? C
2. Some A are B, Some B are C → A ? C
3. A > B, B > C → A ? C
4. A > B, B < C → A ? C
