Question: There were 60 women at the party, and three-fourths of these women were married and brought their husbands with them to the party. If 3/4 of the men at the party were single, how many people attended the party?
Answer: 60 x 3 / 4 = 45 females are married which means there are also 45 married males. If 1 / 4 of the men are married, which represents 45 men, then 4 * 45 = 180 is the total number of men who attended the party. Thus, there are a total of 60 women and 180 men, or a total of 60 + 180 = 240 people at the party. The answer is 240.
