Question

    In this question, three 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 follows/follow from the statements.

    Statements:

    All slates are books.

    Some books are paper.

    Some paper are boards.

    Conclusions:

    I. Some books are slates.

    II. All books are paper.

    III. Some boards are paper.

    A Only conclusions I and II follow. Correct Answer Incorrect Answer
    B Only conclusions I and III follow. Correct Answer Incorrect Answer
    C Only conclusion I follows. Correct Answer Incorrect Answer
    D None of the conclusions follows Correct Answer Incorrect Answer

    Solution

    All slates are books (A) → Conversion → Some books are slates (I). Hence conclusion I follows. Some books are paper (I) → I.I. → No conclusion. Hence conclusion II does not follow. Some paper are boards (I) → Conversion → Some boards are v (I). Hence conclusion III follows.
