    Question

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

    Statements: Some tigers are lions.        

     No lion is a leopard.                             Some leopards are Fox. Conclusions:I. No leopard is a tiger. II. Some tigers are leopards.
    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 conclusion II follows. Correct Answer Incorrect Answer
    D If neither conclusion I nor conclusion II follows. Correct Answer Incorrect Answer
    E If both conclusion I and conclusion II follows. Correct Answer Incorrect Answer

    Solution

    I + E = O, Hence, neither conclusion I nor II will follow. However, Conclusion I and II make a complementary pair, hence, either conclusion I or II will follow. ALTERNATE METHOD: All possible cases: In case A, no leopard is a tiger and in case B & C some tigers are leopard. Thus, either of them is true.
