  • C. If both the Statement I and II together are needed to answer the question
  • D. If either the Statement I alone or Statement II alone is sufficient to answer the question

  • Correct Answer
  • If the Statement II alone is sufficient to answer the question but the Statement I alone is not sufficient 

    Explanation

    From Statement II,
    The ratio of their ages after 5 yr is 7 : 6
    So, (6k + 5) / (5k + 5) = 7/6
    ? 36k + 30 = 35k + 35
    ? 36k - 35k = 35 - 30
    ? k = 5
    ? Age of anand = 6 x 5 = 30 yr
    So, Statement II is alone sufficient.
