Important for :

1

D

Given :Chatur complete | ( | 3 | ) |
^{th} |
of assignment in 72 days |

5 |

Therefore,

Chatur could complete the whole assignment in

72 × 5 | = 120 days |

3 |

Now,

(Ankur + Bhanu + Chatur) worked for 6 days.

So,

Parts of assignment completed in first six days = | 6 |

20 |

Now, according to the question

(Bhanu + Chatur) worked for 4 days

So,

Parts of assignment completed in these four days

= 1 – | ( | 3 | + | 6 | ) | = 1 – | 9 | = | 1 |

5 | 20 | 10 | 10 |

Therefore,

(Bhanu + Chatur) could complete the whole assignment in (10 × 4) = 40 days

Let Bhanu could complete the whole assignment working alone in x days. Therefore,

Let Bhanu could complete the whole assignment working alone in x days. Therefore,

1 | + | 1 | = | 1 |

x | 120 | 40 |

40 (120 + x) = 120x

120x – 40x = 4800

x = 60

Hence, this is the required solution.

Therefore, option D is correct.

2

B

Let Rajeev’s present age = xHis father’s present age = 3x

Grandfather’s present age = 6x

⇒ | x + 3x + 6x | = | 110 |

3 | 3 |

⇒ 10x = 110

⇒ x = 11

Rajeev’s present age = 11 years

10 years ago Rajeev’s age = 1 year

His father’s present age = 33 years

10 years ago = 23 years

His grandfather’s present age = 66 years

10 years ago = 56 years

Required ratio = 1: 23: 56

Hence, option B is correct.

3

D

Let Meenu has Rs xFor simplification, x = LCM (40, 90) = 360

Thus, price of one book = | 360 | = Rs. 9 |

40 |

Similarly, price of one pen = | 360 | = Rs. 4 |

90 |

Now, amount left after keeping money for food = Rs. (360 – 20% of 360) = Rs. 288

Price of 36 pens, P = 4 × 36 = Rs. 144

Amount left = Rs. (288 – 144) = Rs. 144

Therefore, No. of books Meenu buys = | 144 | = 16 |

9 |

Hence, option D is correct.

4

D

Quantity of type A milk = 24 × | 7 | = 14 liters |

12 |

Quantity of type B milk = 24 × | 5 | = 10 liters |

12 |

SP of mixture = 24 × 56 = Rs.1344

CP of mixture when sold at 12% profit

= 1344 × | 100 | = Rs.1200 |

112 |

CP of type A milk = 14 × 45 = Rs.630

CP of type B milk = Rs. (1200 – 630) = Rs.570

Per liter CP of type B milk = | 570 | = Rs. 57 |

10 |

Hence, option D is correct.

5

B

Let total members = NMembers in room A = 33 | 1 | % of N = | N |

3 | 3 |

Members in room B = N – | 100N | = | 2N |

3 | 3 |

According to question-

⇒ | N | + 20 = | N |

3 | 2 |

⇒ 20 = | N |

6 |

⇒ N = 120

Now, if 20 members from room A are shifted to room B-

⇒ | N | – 20 | |||

3 | × 100 = | 20 | × 100 = 16.67% | ||

N | 120 |

Hence, option B is correct.
