Question 1090104
 In a party 68% of people who attend the party are men
let x = total people at the party initially
then
.68x = no. of men
and, obviously:
.32x = no of women
:
 if 40% of the men and 31.2 % of total number of persons left the party than what percent of women left the party
Find the no. of men that left the party
.40(.68x) = .272x men left the party 
:

.312x people left the party
:
.312x - .272x = .04 only 4% of the women left the party
