A feed to a distillation column contains 50 wt. % methanol and

A feed to a distillation column contains 50 wt. % methanol and 50 wt. % of water. The column produces an overhead stream which is 95 wt. % methanol and 5 wt. %water, and a bottom stream which is 20 wt.% methanol and 80 wt. % of water. For 100 kmol/h of feed, determine the flowrates of the overhead and bottom streams in kmol/h.
