Explanation:

Commission up to 10000 = = 900

Again after 10000,

Commission : Bonus

9 : 3

3x : x

Bonus =

A) 3241 | B) 2457 |

C) 2642 | D) 2834 |

Explanation:

Let the total number of votes polled in the election be 100k.

Number of valid votes = 100k - 20% (100k) = 80k

Let the number of votes polled in favour of K and L be a and b respectively.

a - b = 15% (100k) => a = b + 15k

=> a + b = b + 15k + b

Now, 2b + 15k = 80k and hence b = 32.5k

It is given that 100k = 8720

32.5k = 32.5k/100k x 8720 = 2834

The number of valid votes polled in favour of L is 2834.

A) 8800 | B) 8650 |

C) 8000 | D) 8980 |

Explanation:

Let the amount collected be 'A'

Then, from the given conditions,

A x 110/100 x 90/100 = 7920

A x 0.99 = 7920

A = 7920/0.99

=> 8000

A) 65 : 124 | B) 42 : 625 |

C) 21 : 125 | D) 37 : 442 |

A) 7500 | B) 6200 |

C) 5600 | D) 4700 |

Explanation:

Let the candidates be A & B

35%-----------A

65%-----------B

Difference of votes (65-35)% = 30%

=> 30% ------- 2250

Then for 100% -------- ? => 7500

A) 10.769 % | B) 11.23 % |

C) 10.4 % | D) 9.87 % |
