Question

    The question consists of two statements numbered “I and II” given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

    'X' covers 300 km is 'a' hours and 'Y' covers 'd' km in

    'b' hours. Find a:b Statement I: d = 500 Statement II: Speed of both is same. 
    A 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 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 The data either in statement I alone or in statement II alone are sufficient to answer the question. Correct Answer Incorrect Answer
    D The data given in both statements I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer
    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.
