Another motorist equally lost came to a fork in the road. There was no signpost so he had to ask at a house which was the correct fork to take him to his destination. In the house were two brothers, one of whom always told the truth and other who always lied. When one of them (he didn’t know which) came to the door he could ask him only one question. What is the single question he could ask which would ensure he found out the right road?
