    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: Some Manual are Banner. All Operation are Banner. No Operation is Pamphlet. Conclusions: I. No Banner is Pamphlet. II. Some Banner are Operation. III. Some Manual are Pamphlet.
    A All the conclusions follow. Correct Answer Incorrect Answer
    B Only conclusion II follows. Correct Answer Incorrect Answer
    C Only conclusions II and III follow Correct Answer Incorrect Answer
    D Only conclusions I and III follow. Correct Answer Incorrect Answer

    Solution

    No Operation is Pamphlet (E) → Conversion → No Pamphlet is Operation (E) + All Operation are Banner (A) → Some Banner are not Pamphlet (O*). Hence conclusion I does not follow.   All Operation are Banner (A) → Conversion → Some Banner are Operation (I). Hence conclusion II follows. Some Manual are Banner (I) + Some Banner are Operation (I) → No conclusion. Hence conclusion III does not follow.
