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. |

The age of Praduman and Nandini are in the ratio 7 : 5, what is the age of Praduman?

I: |
The ages of Praduman and Gunit are in the ratio 3 : 1. |

II: |
After 7 years the ratio of Praduman’s and Avril’s age will be 4 : 3. |

Let the age of Praduman be years. Let age of Nandini be years.

∴ From the given problem

As ratio is 7:5 or

I: Let the age of Gunit = years

?∴

∴

II: Let age of Avril=years

∴

Statement I and II together are not capable to give the answer, to get the answer more data are needed.

Choice (e) is correct.
