Important for :

1

D

Amount goes to charity = | 5 | × 75000 = Rs. 3750 |

100 |

Amount goes to Ram as a working partner

= | 10 | × 75000 = Rs. 7500 |

100 |

Remaining amount = Rs. (75000 – 3750 – 7500) = Rs. 63750

Share of Ram in the remaining profit = | 2 | × 63750 = Rs. 25500 |

5 |

Total share of Ram = Rs. (7500 + 25500) = Rs. 33000

Hence, option D is correct.

2

B

Let x and y be the mass of 1st alloy and 2nd alloy.aluminium in the 1st alloy = | 85x |

100 |

copper in the 1st alloy = | 8x |

100 |

iron in the 1st alloy = | 7x |

100 |

According to question, for copper

8x | |

100 | × 100 = 5 |

x + y |

8x = 5x + 5y

3x = 5y

x | = | 5 |

y | 3 |

x = 5 and y = 3

Let p = percentage of aluminium in the 2nd alloy

According to question,

5 × | 85 | + 3 × | p | = (5 + 3) × | 75 |

100 | 100 | 100 |

3p = 175

p = | 175 | = 58.33% |

3 |

Hence, option (B) is correct.

3

A

SI for 2 years = Rs.2000SI for 1 year = Rs.1000

In the 2nd year Rs.50 is added in CI which is 5% of 1000

Hence, R = 5%

⇒ 5% = 1000

⇒ 100% = 20000

Sum = Rs.20000

CI for 3 years = 20000 | ( | 105 | ) |
^{3} |
– 20000 |

100 |

⇒ 23152.5 – 20000

⇒ 3152.5

Required ratio = 2050 : 3152.5

⇒ 20500 : 31525

⇒ 820 : 1261

Hence, option A is correct.

4

B

P (getting at least 2 heads) = 1 – P (getting no head or exactly one head)P (getting no head) = P (getting all tails) = | 1 |

16 |

Now, P(exactly one head) :

Getting exactly one head means 3 tails and 1 head in any order and the total occurrences here are

= | 4! | = 4 |

3! |

Therefore, P(getting exactly one head)

= | 4 | = | 1 |

16 | 4 |

Hence, P(getting at least 2 heads)

= 1 – | ( | 1 | + | 1 | ) | = | 11 |

16 | 4 | 16 |

Hence, option B is correct.

5

B

Let P be revenue from each apple and orange.Cost of apples = P × | 100 | = | 5P |

120 | 6 |

Cost of oranges = P × | 100 | = | 4P |

125 | 5 |

Let the number of apples sold by the fruit vendor be 2n, then the number of oranges sold would be 3n.

Cost price of each apple = | 1 | × | 5P | = | 5P |

2n | 6 | 12n |

Cost price of each orange = | 1 | × | 4P | = | 4P |

3n | 5 | 15n |

Therefore, reqd. ratio = | 4P | : | 5P | = 16 : 25 |

15n | 12n |

Hence, option B is correct.
