    Practice Syllogism Now →

    Syllogism is one of the most important reasoning topics, testing your ability to draw logical conclusions from given premises using Venn diagrams.

    What is Syllogism?

    Syllogism presents premises (statements using words like All, Some, No) and asks you to determine which conclusions necessarily follow. It's based on formal deductive logic.

    Why is it Important?

    Syllogism carries 3-5 marks in most banking exams and management entrance tests. With Venn diagram technique, it can be solved with near-100% accuracy.

    Key Techniques

    • Draw Venn diagrams for all possible interpretations
    • Know the rules: All A are B, Some A are B, No A is B
    • "Some" means "at least one" — could be all
    • Conclusions must be true in ALL possible Venn diagram configurations
    • Use the complementary pair technique for "either-or" conclusions

    Common Patterns

    •All-Some-No combinations
    •Possibility-based conclusions
    •Either-or (complementary pair) conclusions
    •Negative conclusions (Some A are not B)

    💡 Pro Tips

    1.Always draw multiple Venn diagrams to cover all cases

    2.A conclusion is valid only if true in EVERY possible diagram

    3."Some A are B" also means "Some B are A" (converse is valid)

    4."All A are B" does NOT mean "All B are A"
