    Question

    Two statements are given, followed by three conclusions

    numbered I. II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: Some papers are pens. No pen is pencil. Conclusions: I. No paper is a pencil. II. Some pens are papers. III. No pencil is a paper.
    A Only conclusions II and III follow. Correct Answer Incorrect Answer
    B Only conclusion II follows. Correct Answer Incorrect Answer
    C Only conclusion I follows. Correct Answer Incorrect Answer
    D Only conclusions I and III follow. Correct Answer Incorrect Answer

    Solution

    Some papers are pens (I) + No pen is pencil (E) → Some papers are not pencils (O). Hence neither conclusion I nor III follow. Some papers are pens (I) → Conversion → Some pens are papers (I). Hence conclusion II follows.
