You are separating an ideal binary mixture of acetone and ethanol

You are separating an ideal binary mixture of acetone and ethanol in a fractionating column. The mixture contains 60 mol% ethanol and is 60% vaporized under column conditions. You desire a distillate containing 95 mol% acetone and a bottoms containing no more than 5 mol% acetone. What is the required number of trays for a reflux ratio of 3 and tray efficiency of 65%? Use the table below for the equilibrium data.
