Let x = total people in room
35=.2x
x = 35/.2 = 175 total people
So there are 175 -35 = 140 women
Lucky men!!

If 35 are men, then their percentage =(100-80)%
= 20%
ratio is 0.2 to 0.8 =1 : 4
=35 : 35x4
=140
there fore, ther are 140 women.

if 80% are women then 20% are men
let the total no = T
then 20% of T = 35
therefore, 20/100 * T = 35
cross multiply you have 20T=3500
T=3500/20 = 175
so the total no in the room 175
if 80% are women then 80/100 * 175 = 140
so there are 140 women in the room

35 men makes 20 %
(35 x 4 ) <====> (80 % = 20 x4 %)
and thats 140

That means that 20% are men. If 20%=35, you multiply the 35 by 4.
35x4=140

it means 20% r men. let ther b 'x' people in total.
no: of men = 20x/100 = 35
ie, x=3500/20
no: of women = 80%of x= (80/100)*3500/20 = 140.
so, answer is 140.
