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

    Solution

    ATQ, Statement I: d = 500 We don't know speed of both. So, data in statement I alone is not sufficient to answer the question. Statement II: Since, speed of both is same but distance traveled by 'Y' is not known. So, data in statement II alone is not sufficient to answer the question. Combining statement I and II: 300/a = 500/b Or, a:b = 3:5 So, The data in both statements I and II together are necessary to answer the question.
