One hundred people attended a party. Fifty percent of the attendees are women, thirty-five percent of them are men, and the rest are children. How many children attended the party? Think carefully first, then make a decision:
Out of 100 attendees, 100 x 50 / 100 = 50 are women. While 100 x 35 / 100 = 35 are men. So there were a total of 50 + 35 = 85 men and women who attended the party. Thus, 100 - 85 = 15 children attended the party. So, the answer is 15.
