Question 581119
part I   	11.00%		per annum	---x					
part II	-4.00%		per annum	---y					
									
x	+	1	y=	35000	------------------------1				
11.00%	x	+	-4.00%	y=	1900				
Multiply by		100							
11	x	+	-4	y=190000.00		--------2	
									
Multiply (1) by			-11						
we get									
									
-11	x	-11	y=-385000.00			
									
Add this to (2)									
									
-15	y=	=-195000			
									
divide by-15							
									
y	=		13000		investment at	(4.00% )
Balance			22000		investment at	11.00%
CHECK									
13000	---------	-4.00%	-------	-520.00
