Question

    In each question below are given two statements followed by two conclusions numbered I and II. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts. Give Answer:

    Statements: All drafts are frames.

    No frame is a sketch.

    Conclusions: I. No Sketch is a draft.

    II. Some drafts are not sketches.

    A If only conclusion I follows; Correct Answer Incorrect Answer
    B If only conclusion II follows; Correct Answer Incorrect Answer
    C If either conclusion I or II follows; Correct Answer Incorrect Answer
    D If neither conclusion I nor II follows; and Correct Answer Incorrect Answer
    E If both I and II follow. Correct Answer Incorrect Answer

    Solution

    All drafts are frames (A) + No frame is sketch (E) = No draft is a sketch (E). ⇒ Conversion ⇒ No sketch is a draft (E). Hence, conclusion I will follow. All drafts are frames (A) + No frame is sketch (E) = No draft is a sketch (E). ⇒ I.I. ⇒ Some drafts are not sketches(O). Hence, conclusion II will also follow.
