There are seven members in a family, four males and four females. A is wife of C. C has two sons Q and B. T is the mother of R. How is R related to C?

E

A is wife of C. C has two sons Q and B.

Inference: S is son of B. but we do not get information about R. so this statement is not sufficient.

Inference: T is the wife of Q. but no info of R, hence this is also not sufficient.

This statement alone gives us the information that R is the daughter of Q and hence granddaughter of C. therefore statement alone is sufficient to answer the question.

Hence, the correct answer is option E.

There are five floors in a building named from no 1 to 5 in such a way that lowermost floor is numbered as 1 and topmost floor is numbered as 5. Five members live at different floors of the building namely, Rama, Lina, Tina, Charu and Anita, but not necessarily in the same order. Also these five work in different companies namely, A, B, C, D and E. Tina stays on Floor no 2 and works in company D and Charu stays on floor no 5. Also the one who stays on floor no 1 is working in company A. Then who lives on floor no 3 and in which company does she/he work?

D

Tina stays on Floor no 2 and works in company D and Charu stays on floor no 5. Also the one who stays on floor no 1 is working in company A.

Inference:

5 | Charu | ||

4 | |||

3 | |||

2 | Tina | D | |

1 | A |

Inference: Only Rama is left who will work in company A.

This statement alone is not sufficient to answer the question.

Inference: If Antia does not work in C, so either Lina or Rama will work in company C.

If we take statement 1 and 2 together, we will get the following table:

5 | Charu | ||

4 | |||

3 | C | ||

2 | Tina | D | |

1 | Rama | A |

Taking statement 1 and 3 together, we get the following table:

5 | Charu | ||

4 | |||

3 | Lina | ||

2 | Tina | D | |

1 | Rama | A |

Taking Statement 2 and 3 together, we get the following table:

5 | Charu | ||

4 | |||

3 | Lina/Rama | C | |

2 | Tina | D | |

1 | A |

Taking all three statements together, we get:

5 | Charu | ||

4 | |||

3 | Lina | C | |

2 | Tina | D | |

1 | Rama | A |

Hence to answer the question we need all three statements.

Hence, the correct answer is option D.

Bunty | Nutty | Sweety | Preeti | Neeti | Minty |

Dairy milk | |||||

Snickers-X Perk-X |

Taking together all three statements, we do not get the answer. Hence all three statements together are not sufficient to answer the question.

Bunty | Nutty | Sweety | Preeti | Neeti | Minty |

perk | Snickers | Dairy milk | |||

5 star-x | Perk-X |
Snickers-X Perk-X |
5 Star-X, Snickers-X |

Sparrow | Mango | Bnayan-X |

Parrot | Neem | |

Crow | Palm. | Banyan-X, Mango-X |

Pigeon | Banyan |

Sparrow | Mango | |

Parrot | Neem | |

Crow | Palm. | Banyan-X, Mango-X |

Pigeon | Banyan | Palm-X, Mango-X |

Hence, the correct answer is option C.
