My friend Kim told me:
Last week I went to an afternoon party. I was the last guest to arrive. I looked around and counted (not including myself) altogether 14 grown-ups and 17 children. Altogether, there were 12 male and 19 female present.
Later in the afternoon, the dancing started. There was a lot of dancing. Every boy danced exactly once with every girl, and every man danced exactly once with every woman. The number of children couples that formed during these dances was equal to the number of grown-up couples.
Question: Is Kim a boy? A girl? A man? A woman?
