    Question

    Statement: All grams are metres.

                               No metre is a litre. Conclusions: I. Some litres are not grams.                        II. Some litres may be metre. 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:
    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. Correct Answer Incorrect Answer
    E if both conclusions I and II follow Correct Answer Incorrect Answer

    Solution

    All grams are metres(A) + No metre is a litres(E) ⇒ No gram is a litre(E) ⇒ Conversion ⇒   Some litres are not grams(O). Hence, conclusion I follows. No metre is a litres(E) ⇒ No probable conclusion. Hence, conclusion II does not follow.
