Q: There were 30 women and 20 men who attended the party. After few hours, 2/5 of the total number of people left. If 9 men left the party, how many more women stayed at the party than men?
A:
There were 30 + 20 = 50 attendees at the party. A total of 50 x 2 / 5 = 20 people left the party. Nine of those who left were men while 20 - 9 = 11 of them were women. So, 30 - 11 = 19 women stayed at the party. And 20 - 9 = 11 men stayed at the party. Thus, 19 - 11 = 8 more women than men stayed at the party. The answer is 8.
