    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 days are nights. No night is a date. Conclusions: I. No day is a night. II. No day is a date.
    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

    Solution

    All days are nights (A) ⇒ I.I. ⇒ Some days are nights (I). Hence, conclusion I will not follow. All days are nights (A) + No night is a date (E) = No day is a date (E). Hence, conclusion II will follow.
