NAMES
Three people whose surnames are White, Red and Black happen to meet at a party. Shortly after introducing themselves, the lady says:
-‘It’s funny that our surnames are White, Red and Black and that there are here three people whose hair colours are exactly those three colours’.
The red-haired person answers:
-‘Yes, it really is but you have probably noticed that none of us has the colour corresponding to our surnames’.
-‘True!’ says the person called White.
If the lady hasn’t got black hair, who has it red?


SOLUTION
Mr/Ms White hasn’t got red haired because he/she speaks after the one who is red-haired. He/She hasn’t got white hair because this is his family name so he/she has black hair.
Mr/Ms Red has neither red nor black hair so this is the white-haired person.
The only possibility is for the person called Black to be red-haired. Apart from that the lady can neither be called White nor Black, who answers to her. Thus she is called Red.
SOLUTION: The person who has red hair is Mr. Black.
