Replace each letter by a digit. Each letter must be represented by the same digit and no beginning letter of a word can be 0. O N E O N E O N E + O N E ------- T E N Use trial and error. 0 =1, N = 8 ,E = 2, T = 7 1 8 2 1 8 2 1 8 2 + 1 8 2 ------ 7 2 8 A man is on a search for Atlantis and comes upon an island where all the inhabitants know whether Atlantis is still around or not. However, all of the inhabitants are either Fairies or Trolls and they all use a spell to appear humanoid so you cannot tell which is which. And the Faries always tell the truth and the Trolls always lie, but there is a slight complication, some of the Fairies have gone insane and always lie and some of the Trolls have also gone insane and always tell the truth. So here is your task: you must ask the first inhabitant that you come to ONE question and from that ONE question you must determine wether Atlantis is still around or not. What is the question that you must ask?
