1% of the room is women.
%281%2F100%29X=3
X=300
There are 300 people in the room originally, 3 of them women, 297 of them men.
When the men go to 98%, the women will be at 2%.
3%2FY=0.02
Y=3%2F0.02
Y=150
So then the total population will be 150 people, 3 of them women, 147 men.
So then,
N=297-147=150
150 men have to leave the room.
