Jack is looking at Anne, but Anne is looking at George. Jack is married but George is not. Is a married person looking at an unmarried person?
Yes / No / Cannot be determined
WHO? Kurt Kleiner
More than 80 per cent of people answer this question incorrectly. If you concluded that the answer cannot be determined, you’re one of them. (So was I.) The correct answer is, yes, a married person is looking at an unmarried person.
Most of us believe that we need to know if Anne is married to answer the question. But think about all of the possibilities. If Anne is unmarried, then a married person (Jack) is looking at an unmarried person (Anne). If Anne is married, then a married person (Anne) is looking at an unmarried person (George). Either way, the answer is yes.
