Four golfers named Mr. Black, Mr. White, Mr. Brown, and Mr. Blue were competing in a tournament. The caddy didn’t know their names, so he asked them. One of them, Mr. Brown, told a lie. The 1st golfer said, “The 2nd Golfer is Mr. Black.”
The 2nd golfer said, “I am not Mr. Blue!”
The 3rd golfer said,”Mr. White? That’s the 4th golfer.”
And the 4th golfer remained silent.
Which one of the golfers is Mr. Blue?
