	percent	----------------			quantity							
Saline solution type I	20.00%	----------------			x	ml						
Saline solution type II	5.00%	------	90	-	x	ml						
Mixture	10.00%	----------------	90									
Total	90		ml									
20.00%	x	+	5.00%	(	90	-	x	)	=	10.00%	*	90
20	x	+	5	(	90	-	x	)	=	900		
20	x	+	450	-	5	x	=			900		
20	x	-	5	x			=	900	-	-450		
15	x			=	450							
/	15											
	x			=	30		ml			20.00%		Saline solution type I
					60		ml			5.00%		Saline solution type II
