outstanding and superb last island.very impressed.
here comes mine.
ali wants to go to london by road and in the way there is darkness as he cant see his knee. he doesnt know the way. there are standing two persons.one is dressed in red and another is dressed in green.
a person dressed in red always tells a lie. and the person dressed in green always speaks the truth.
can u tell me what question should ali ask so that he gets the correct answer from the persons standing there?
