Each question below is followed by two statements I and II. You are to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose between the possible answer.

(a) |
If the statement I alone is sufficient to answer the question but the statement II alone is not sufficient. |

(b) |
If the statement II alone is sufficient to answer the question, but the statement II alone is not sufficient. |

(c) |
If both statements 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. |

(e) |
If you cannot get the answer from the statements I and II together but needed more data. |

From given, age of Anand = Age of Surjeet =

From statement we have (after 5 year ratio of ages of Anand and Surjeet is 7:6)

⇒

⇒36(age factor)

∴ Age of Anand = 6years

Therefore statement II is alone sufficient to answer the problem.

∴ Choice (b) is correct.
