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