Question

If thr income of the two persons named x and y are in the ratio 5:4 and there expenditures are in the ratio 4:3.If both of them save 4000 per month find there income and expenditure. ​

Answer 1

Answer: let the income of X=5a

And income of y =4a

Expenditure of x =4b

Expenditure of y=3b

ATQ,

For x, 5a-4b=4000(1)

For y,4a-3b=4000(2)

From eq(1)&(2) we get,

5a-4b=4a-3b

a=b

In eq(1)

5a-4a=4000

a=4000=b

Income of x=5a=5*4000=20000

Income of y=4*4000=16000

Expenditure of x=4*4000=16000

Expenditure of y=3*4000=12000
