part I   	2.00%		per annum	---x					
part II	5.00%		per annum	---y					
									
x	+	1	y=	20000	------------------------1				
2.00%	x	+	5.00%	y=	550				
Multiply by		100							
2	x	+	5	y=	=	55000.00		--------2	
									
Multiply (1) by			-2						
we get									
									
-2	x	-2	y=			-40000.00			
									
Add this to (2)									
									
0	x	3	y=	=		15000			
									
divide by		3							
									
y	=	5000		investment at	5.00%
Balance	15000 	investment at	2.00%
