This is for a distillation column. The feed to the column

This is for a distillation column.

The feed to the column is 150 lb/hr of 20 mol% Ethanol in water, the steam to the reboiler is 100 lb/hr, the overhead composition is controlled at 70 mol% ethanol, and the bottom product is 1 mol% ethanol. If the steam to the reboiler is changed from 100 lb/hr to 120 lb/hr and the bottoms product remains at 1 mol%, what is the new flowrate of top product
