Question 1 |

A sum of money is to be distributed among A, B, C, D in the proportion of 5 : 2 : 4 : 3. If C gets Rs. 1000 more than D, what is B's share?

Rs. 500 | |

Rs. 1500 | |

Rs. 2000 | |

None of these |

Question 1 Explanation:

Let the shares of A, B, C and D be Rs. 5x, Rs. 2x, Rs. 4x and Rs. 3x respectively.
Then, 4x - 3x = 1000
x = 1000.
B's share = Rs. 2x = Rs. (2 x 1000) = Rs. 2000.

Question 2 |

Salaries of Ravi and Sumit are in the ratio 2 : 3. If the salary of each is increased by Rs. 4000, the new ratio becomes 40 : 57. What is Sumit's salary?

Rs. 17,000 | |

Rs. 20,000 | |

Rs. 25,500 | |

Rs. 38,000 |

Question 2 Explanation:

Let the original salaries of Ravi and Sumit be Rs. 2x and Rs. 3x respectively.
Then, (2x + 4000)/(3x + 4000) =40/57 ==>57(2x + 4000) = 40(3x + 4000) ==> 6x = 68,000 ==> 3x = 34,000
Sumit's present salary = (3x + 4000) = Rs.(34000 + 4000) = Rs. 38,000.

Question 3 |

If 0.75 : x :: 5 : 8, then x is equal to:

1.12 | |

1.2 | |

1.25 | |

1.30 |

Question 3 Explanation:

(x x 5) = (0.75 x 8) ==> x =(6/5)= 1.20

Question 4 |

If Rs. 782 be divided into three parts, proportional to 1/2 :2/3 :3/4 , then the first part is:

Rs. 182 | |

Rs. 190 | |

Rs. 196 | |

Rs. 204 |

Question 4 Explanation:

Given ratio = 1/2 :2/3 :3/4 = 6 : 8 : 9.
1st part = Rs. (782 x 6/23)= Rs. 204

Question 5 |

The fourth proportional to 5, 8, 15 is:

18 | |

24 | |

19 | |

20 |

Question 5 Explanation:

Let the fourth proportional to 5, 8, 15 be x.
Then, 5 : 8 : 15 : x
==> 5x = (8 x 15)
x =(8 x 15)/5= 24.
