# Job Roles

A) 5/7 | B) 5/14 |

C) 1/7 | D) 1/14 |

Explanation:

Required probability = $\frac{(10+3)}{91}=\frac{13}{91}=\frac{1}{7}$

A) 3/14 | B) 2/91 |

C) 9/182 | D) 7/545 |

Explanation:

Required probability = $\frac{3\times 6}{364}=\frac{9}{182}$

A) I and II | B) I and III |

C) Only III | D) I and either II or III |

Explanation:

From I and II,

Length = 3x = 48 m

∴ x = 16

Breath = 2x = 32 m

Hence, Area of floor = 48 × 32

Cost of flooring = 48 × 32 × 850 = ₹ 1305600

From I and III, 2(l +b) = 160

2(3x + 2x) = 160

10x = 160

∴ x = 16

∴ Length = 3 × 16 = 48 m

Breadth = 2x = 32m

Cost of flooring = (48 × 32) × 850 = ₹ 1305600

Similarly, from II and III, we can find

l = 48 m

b = 32 m

and Total cost of flooring = ₹ 1305600

A) None of the statements can be dispensed with | B) Only I |

C) Only II | D) Any one of the three |

Explanation:

From I No. of students studying in A and B are 3x and 4x respectively.

From II No. of students studying in B who got placement = (4x × 80) ÷ 100 = 16x/5

Hence Question cannot be answered even with the information in all the three statements

Hence option 5 is correct

A) If 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. | 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. |

C) The data either in statement I alone or in statement II alone are sufficient to answer the question. | D) If the data in statement I and II together are not sufficient to answer the question. |

A) Any two of the three | B) Only II and III |

C) All I, II and III | D) Question cannot be answered even with the information in all the three statements |

Explanation:

Suppose marked scored by Abhijit in English = x

From statement I,

Marks in science = x + 12

From statement III,

Marks in mathematics = x + 12 + 20

= x + 32

From statement II,

English + Science + Mathematics = 198

x + x +12 + x + 38 = 198

3x = 154

x = 154/3

All I, II and III are required to find answer.

A) South America | B) Africa |

C) North America | D) Europe |
