Best answer 29 votes 29 votes Assume $100$ people are invited, so $60$ men and $40$ women invited. During the party only $80$ people showed up, and since all women attended $\Rightarrow 80 = 40 +$ men Therefore, men $= 40$ men : women $= 1:1$ Correct Answer: $B$ Wantei Warjri 1 answered Feb 4, 2018 edited Jun 20, 2021 by Lakshman Bhaiya Wantei Warjri 1 comment Share Follow See all 0 reply Please log in or register to add a comment.

5 votes 5 votes Lets say 100 people are invited. 60 male, 40 female. Total 80 people came. All female came too. So x+40= 80 => x = 40 male came. Male/Female = 1:1 Ahwan answered Feb 14, 2018 Ahwan comment Share Follow See all 0 reply Please log in or register to add a comment.
