Each of the questions given below has one question and two statements marked I and II. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements.
    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 in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D If the data even in both the statement I and II together are not sufficient to answer the question Correct Answer Incorrect Answer
    E If the data in both statement I and II together are needed to answer the question. Correct Answer Incorrect Answer

    Solution

    From I. Number of sons = 8. Number of daughter = 1. Hence, the total number of total children = 8 + 1 = 9 From II. Suppose number of daughter = x Hence, the number of total children = 8 x + x = 9 x Still we need the value of x. Hence II alone is not sufficient.
