A young woman attending a party was introduced to 4 men in rather rapid succession and, as usual at such gatherings, their respective types of work were mentioned rather early in the conversation. Unfortunately, she was afflicted with a somewhat faulty memory. Half an hour later, she could remember only that she had met a Mr. Brown, a Mr. White, Mr. Green and a Mr. Black. She recalled that among them were a photographer, a grocer, a banker, and a singer, but she could not recall which was which. Her hostess, a fun-loving friend, refused to refresh her memory, but offered 4 clues. Happily, the young woman’s logic was better than her memory, and she quickly paired each man with his profession. Can You? Here are the clues:
1. Mr. White recently approached the banker for a loan.
2. Mr. Brown had met the photographer when he hired him to take pictures of his wedding.
3. The singer and Mr. White are friends, but have never had business dealings.
4. Neither Mr. Black nor the singer had ever met Mr. Green before that evening.
