Part I	9.00%		per annum	-------------	Amount invested =x	
Part II	11.00%		per annum	------------	Amount invested = y	
	12000					
Interest-----	1180.00					
						
Part I	9.00%		per annum	---x		
Part II	11.00%		per annum	---y		
Total investment						
x	+	1	y=	12000	-------------1	
Interest on both investments						
9.00%	x	+	11.00%	y=	1180	
Multiply by		100				
9	x	+	11	y=	118000.00	--------2
Multiply (1) by			-9			
we get						
-9	x	-9	y=	-108000.00		
Add this to (2)						
0	x	2	y=	10000		
divide by		2				
			y	=	5000	
Part I	9.00%	Rs	7000			
Part II	11.00%	Rs.	5000
