Important for :

1

A

Let Rinku bought total 2 mangoes, one for Rs. 30 and other for Rs. 50 then the average price of both mangoes= Rs. | 80 | = Rs. 40 |

2 |

Now he wants to gain 16.67%

= | ( | 1 | ) | % on Rs. 40 |

6 |

The selling price = 40 × | (100 + 16.67) |

100 |

= 40 × | 7 | = 46.67 approximately |

6 |

Hence, option A is correct.

2

A

Let the principal = Rs. P
Then SI for 3 years @ 8% per annum
= | P × R × T | = | P × 8 × 3 | = 250 |

100 | 100 |

CI for 3 years @ 12% per annum on 1041.67

CI = P | ( | 1 + | R | ) |
^{N} |
– P |

100 |

= 1041 | ( | 1 + | 12 | ) |
^{3} |
– 1041.67 |

100 |

= Rs. (1463.47 – 1041.67) = Rs. 421.8

The required difference = Rs. (421.8 – 250) = Rs. 171.8 = Rs. 172 approximately

Hence, option A is correct.

A

The total distance travelled by Rajdhani express till 11: PM = 96 × 2 = 192 KmRemaining distance = (540 – 192) Km = 348 Km

The relative speed = (96 + 49) = 145 km/hr The time when both train will collide

= | 348 | = 2.4 hours = 2 hours 24 mins |

145 |

Hence, option A is correct.

4

E

The age of grandfather = x yearsAnd the age of son = y years According to the question,

(x + y) | = | 5 |

(x – y) | 4 |

By Solving we get,

x | = | 9 |

y | 1 |

Let us assume x = 9z and y = z

Then, | (9z + 5) | = | 5 |

(z + 5) | 1 |

the required difference = x – y = 9z – z = 8z = 40 years.

Hence, option E is correct.

5

A

The respective ratio of milk and water in a solution is 7 : 9,

in another mixture, quantity of milk = 50% of 8 litres = 4 litres and hence the quantity of water = 8 – 4 = 4 litres

Let the quantity of milk in original mixture = 7x litres and the quantity of water = 9x litres

in another mixture, quantity of milk = 50% of 8 litres = 4 litres and hence the quantity of water = 8 – 4 = 4 litres

Let the quantity of milk in original mixture = 7x litres and the quantity of water = 9x litres

Then according to the question,

(7x + 4) | = | 4 |

(9x + 4) | 5 |

The original quantity of milk = 7x = 7 × 4 = 28 litres

Hence, option A is correct.
