    A If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question. Correct Answer Incorrect Answer
    B If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question. Correct Answer Incorrect Answer
    C If the data either in statement I alone or statement II alone are sufficient to answer the question. Correct Answer Incorrect Answer

    E If the data in both statement I and II together are necessary to answer the question. Correct Answer Incorrect Answer

    Solution

    From I and II Let the number be 10x + y Now, x + y = 9……..(i) ∴ x = 125/100 y = 5/4 y………(ii) From (i) and (ii), we get x = 5, y = 4 ∴ Required number = 54
