Important for :

1

A

Let total female are 200x and total male are 300x.

Passed female = 35% of 200x = 70x and passed male = 40% of 300x = 120x

Difference between passed male and female = 120x – 70x = 50

⇒ x = 1

Total marks scored by passed candidates = (70 × 1 × 280) + (120 × 1 × 320) = 58000

Hence, option (A) is correct.

Hence, option (A) is correct.

2

3

B

Let the ratio in which 2 mixtures are mixed = x : y.Per cent of water in the final mixture = 36.8%

Per cent of water in first mixture

= | 48 – 32 | × 100 = | 100 | % |

48 | 3 |

Per cent of water in second mixture

= | 32 –20 | × 100 = 37.5% |

32 |

By the rule of allegation-

⇒ Ratio = | Water in second – Water in final |

Water in final – Water in first |

⇒ x : y = | 37.5 – 36.8 | |

36.8 – | 100 | |

3 |

⇒ x : y = | 0.7 |

10.4 | |

3 |

= 2.1 : 10.4 = 21 : 104

Hence, option B is correct.

4

C

One day work of a man = 1 unit

Total work = 4 × 11 = 44 units

If on each subsequent day a new man joined -

The work on 2nd day = 2 unit

The work on 3rd day = 3 unit

So on….

Than for the first 8 days the total work = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36 units

Remaining work = 44 – 36 = 8 units

This remaining 8 unit of work will be completed in 1 more day as 8 men are employed in the work.

Hence total time taken = 8 + 1 = 9 days.

Therefore, option C is correct.

5

C

Let cost price of each book = ‘P’.

Books sold at 10% profit = 20% of 100 = 20

Books sold at 15% profit = 37.50% of 80 = 30

Books sold at 8% profit = 80% of 50 = 40

Books sold at 20% profit = 100 – 20 – 30 – 40 = 10

Total SP of books = [20 × 1.1P] + [30 × 1.15P] + [40 × 1.08P] + [10 × 1.2P] = 22P + 34.5P + 43.2P + 12P = 111.7P

Total SP when all the books are sold at 16% profit = 116% of 100 × P = 116P

Difference = 116P – 111.7P = 1505 (Given)

⇒ 4.3P = 1505

⇒ P = 350

Hence CP of each book = Rs.350

Therefore, option C is correct.

Hence CP of each book = Rs.350

Therefore, option C is correct.
