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=

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
