THE RATIO OF ANNUAL INCOMES OF A AND B IS 4 :3 AND THEIR ANNUAL EXPENDITURE IS 3 :2 IF EACH OF THEM SAVES SHILLINGS 1000 A YEAR FIND THEIR ANNUAL INCOMES?

Annual Income of A=

and

Annual Income of B=

Step-by-step explanation:

Given Data:

Ratio of annual income of A and B=4:3

Ratio of expenditures of A and B=3:2

Saving of A and B=1000

Required: Annual Income of A and B=?

Solution:

If ratio of income of A and B is 4:3

then let Income of A= and Income of B=

If ratio of expenditure of A and B is 3:2

then let expenditure of A= and expenditure of B=

Therefore,

      ...........

and ..........

subtracting Eq(1) and Eq(2), we get

putting in Eq(1), we get value of as

because x and y are equal in Eq (3)

Now, Annual Income of A=

and Annual Income of B=

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
