<PRE><B>Question 428486</B>
Below an interest of Rs 2400 one  investment becomes negative. not possible

I have worked with Rs. 2550. as interest. instead of Rs 2250. 

Part I	8.00%		per annum					
Part II	10.50%		per annum					
								
x		+	y	30000	------------------------1			
8.00%x+10.50%y=	Rs2,550.00		
Multiply by 100						
8x+10.5y	=Rs255,000.00		--------2
								
Multiply (1) by 	-8					
we get								
								
-8x-8y=	-240000.00		
								
Add this to (2)								
								
2.5y=$15,000.00		
								
divide by 2.5						
								
y=Rs.6,000.00	investment at at 10.5%
Balance	Rs.24,000.00 investment at 8%
