Question 605073
	percent	----------------			quantity								
Acid solution I	20.00%	----------------			x	ml							
Acid solution II	45.00%	------	100	-	x	ml							
Mixture	30.00%	----------------	100										
	12												
20.00%x+45.00%(100-x)=	30.00%	*100	
20x+45	(100-x)	=3000			
20x+4500-45x=3000			
20x-45x=3000-4500			
-25x=	-1500								
/	-25												
x=60	ml			20.00%		Acid solution I	
40		ml	45.00%		Acid solution II
