[Distillation] A process plant needs two ethyl-alcohol-water solutions, one containing 89% ethanol and the other 60% ethanol. A dilute mixture containing 35% ethanol is available. The 60% solution is withdrawn at the rate of 1000 kg/h. If the bottoms is to contain no more than 3% ethanol and only 5% of the alcohol in the feed should be lost in this stream, calculate the flow rates of all the unknown streams.
