Mr. Black, Mr. Brown and Mr. Green were all eating together at a restaurant.
Each was wearing a coloured tie. The ties were black, brown and green in colour.
Suddenly the man wearing the green tie said:
“Did you notice that our ties are the same colour as our names but no one is wearing a tie that matches his name? “Strange, indeed”, said Mr. Black.
What colour tie was each man wearing?
Mr. Black = brown
Mr. Brown = green
Mr. Green = black
