Annual Income of B=
<u>Step-by-step explanation:</u>
<u>Given Data:</u>
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
<u>Required:</u> Annual Income of A and B=?

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 is D
BE
