<PRE><B>Question 751939</B>
a:b =3:2
let income of A is 3x
and income of B is 2x
same way expenditure ratio is 5:3
let expenditure of A is 5y
and expenditure of B is 3y

saving of A will be  3x-5y =1000 (i) multiplied by 3
saving of B  will be 2x-3y =1000  (ii) multiplied by 5
we will get 
9x-15y =3000
10x-15y  =5000
by elimination method 
-x =-2000
x =2000
income of A will be 3x=6000
                 income of A  = 6000
income of B will be  2x  =2x2000 =4000
ANSWER income of RS 4000</PRE>
