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 bottle are cups.

                               No cup is a plate.

    Conclusions:    I. No bottle is a plate.

                             II.Some plates are not cups.

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

    Solution

    Alternate: All bottle are cups (A) + No cup is plate (E) = No bottle is a plate (E). Hence, conclusion I will follow. No cup is plate (E) ⇒    Conversion ⇒ No plate is a cup⇒ I.I. ⇒ some plates are not cups (O). Hence, conclusion II will also follow.
