	$R_{x} = 96 / k g R_{y} = 112 / k g R_{m i x} = \frac{72}{0.7} / k g$ $\frac{w_{x} R_{x} + w_{y} R_{y}}{w_{x} + w_{y}} = R_{m i x}$ $\frac{w_{x} \times 96 + w_{y} \times 112}{w_{x} + w_{y}} = \frac{720}{7}$ $720 w_{x} + 720 w_{y} = 672 w_{x} + 784 w_{y}$ $48 w_{x} = 64 w_{y}$ $\frac{w_{x}}{w_{y}} = \frac{64}{48} = \frac{4}{3} s o w_{x} : w_{y} = 4 : 3$
