DATOS
A= x
a = 20% = 0.2
B= 20lt
b = 12%= 0.12
C= 20+x
c = 16% = 0.16
BALANCE DE SOLUTO
aA + bB = cC
0.2x + 0.12(20) = 0.16 (20+x)
0.2x + 2.4 = 3.2 + 0.16x
0.2x - 0.16x = 3.2 - 2.4
0.04x = 0.8
x= 0.8/0.04
x= 20 lt
RESPUESTA: Deben agregarse 20 lt de solución al 20% para obtener la solución requerida.
