Question 885867
Part I	4.00%		per annum	-------------	Amount invested =x	
Part II	7.00%		per annum	------------	Amount invested = y	
	2100000	
6% of 21,000,000 = 126,000				
Interest-----	126000.00					
						
Part I	4.00%		per annum	---x		
Part II	7.00%		per annum	---y		
Total investment						
x	+	1	y=	2100000	-------------1	
Interest on both investments						
4.00%	x	+	7.00%	y=	126000	
Multiply by		100				
4	x	+	7	y=	12600000.00	--------2
Multiply (1) by			-4			
we get						
-4	x	-4	y=	-8400000.00		
Add this to (2)						
0	x	3	y=	4200000		
divide by		3				
			y	=	1400000	
Part I	4.00%	$	700000			
Part II	7.00%	$	1400000			
						
CHECK						
700000	---------	4.00%	-------	28000.00		
1400000	-------------	7.00%	-------	98000.00		
Total			--------------------	126000.00
