The incomes of two persons A and B are in the ratio 3 : 4. If each saves Rs.100 per month, the ratio of their expenditures is Rs. 1 : 2. Find their incomes.

A) Rs. 100 and Rs.150 | B) Rs. 150 and Rs.200 |

C) Rs.200 and Rs.250 | D) Rs.250 and Rs.300 |

Explanation:

Let the incomes of A and B be 3P and 4P.

If each saves Rs. 100 per month, then their expenditures = Income - savings = (3P - 100) and (4P - 100).

The ratio of their expenditures is given as 1 : 2.

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

Solving, We get P = 50. Substitute this value of P in 3P and 4P.

Thus, their incomes are : Rs.150 and Rs.200

Subject: Ratio and Proportion - Quantitative Aptitude - Arithmetic AbilityDivide Rs.6500 among A,B and C so that after spending 90% , 75% and 60% of their respective saving were in the ratio of 3: 5: 6

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

Subject: Ratio and Proportion - Quantitative Aptitude - Arithmetic AbilityRs. 5625 is to be divided among A, B and C so that A may receive 1/2 as much as B and C together receive and B receives 1/4 of what A and C together receive. The share of A is more than that of B by

A + B + C = 5625

4B + B = 5625

B = 1125

Also A + C = 4B = 4 x 1125 = 4500

Also

B = 2A - C

2A - C = 1125

Now solving A+C = 4500 and 2A-C = 1125

Then A = 1875 and C = 2625

A-B = 1875 - 1125 = Rs. 750
