    Question

    Find the number of females in an office.

    Statement I:  The ratio of number of males to females is 5: 4. Statement II:  The number of males is 25% more than the number of females.
    A If the question can be answered with the help of both the statements but not with the help of either statement itself Correct Answer Incorrect Answer
    B If the question cannot be answered even with the help of both the statements. Correct Answer Incorrect Answer
    C If the question can be answered with the help of statement II alone. Correct Answer Incorrect Answer
    D If the question can be answered with the help of statement I alone. Correct Answer Incorrect Answer
    E If the question can be answered with the help of either statement alone. Correct Answer Incorrect Answer

    Solution

    Let the number of males = x and number of females = y. From I,   => x/y = 5/4 Therefore, x  = 1.25y From II, => x = y + 25% of y = 1.25y Since both the statements give the same equation, statement I and II both are not sufficient to answer the question.
