A's spending 90% saving = 10%

B's spending 75% saving = 25%

C's spending 60% saving = 40%

Let us suppose A, B and C saves Rs. 3.5 and 6 respectively.

10% of A's saving = Rs.3

100% of A's saving = = Rs. 30

25% of B's saving = Rs. 5

100% of B's saving = = Rs. 20

40% of C's saving = Rs.6

100% of C's saving = = Rs. 15

Divide Rs. 6500 in the ratio of 30 : 20 : 15 as

A's Share = = Rs. 3000

B's Share = = Rs. 2000

C's Share = = Rs. 1500

A) 18 : 24 : 11 | B) 9 : 15 : 1 |

C) 20 : 15 : 9 | D) 21 : 7 : 3 |

Explanation:

Given k : l = 4 : 3

l : m = 5 : 3

Then k : l : m = 20 : 15 : 9

A) Rs. 159 | B) Rs. 96 |

C) Rs. 147 | D) Rs. 105 |

Explanation:

K : L : M = 100 : 45 : 30

= 20 : 9 : 6

Given L share is 27

=> 9 ------ 27

35 ------ ?

=> 105

A) 4:5 | B) 6:5 |

C) 3:2 | D) 1:3 |

A) 7 : 9 | B) 9 : 7 |

C) 7 : 4 | D) 7 : 10 |

Explanation:

Given 5:6 :: 7:10 :: 6:5

We know that compound ratio is calculated as

a:b :: c:d :: e:f

(axcxe):(bxdxf)

=> (5x7x6):(6x10x5)

=> (210):(300)

= 7:10

A) 200, 400 | B) 100, 300 |

C) 100, 200 | D) 150, 200 |

Explanation:

The incomes of A and B be 3P and 4P.

Expenditures = Income - Savings

(3P - 100) and (4P - 100)

The ratio of their expenditure = 1:2

(3P - 100):(4P - 100) = 1:2

2P = 100 => P = 50

Their incomes = 150, 200
