Directi Interview Logic Aptitude Puzzle - 30 April

On a certain island, people are gifted with assorted eye colors. There are a hundred green colored and a hundred grey colored pair of eyes. On that island, there is no mirror available. Thus no one knows the eye color of their own. They could have asked each other but that is prohibited. They are not allowed to converse with each other. However, they can study and analyze other's eyes. They don't even know the statistics and so it is believable to them that their eyes can be blue as well. There is a chance of freedom from the island. If anyone is able to guess the color of his own eyes correctly, he will be set free and can leave the island.

On one particular day, an outsider comes to the island and makes an announcement that he has seen someone with grey color eyes. What will happen now?

  1. Assuming that they cannot ask other inhabitants of the island ONLY about the color of their eyes, they can ask the outsider about is since he said that someone had grey colored eyes. They can know he is an outsider since he talked about the eye color of an inhabitant and the people there know that inhabitants cannot do that. Therefore, they will ask the outsider to set themselves free.

  2. after 1 day, if no one ask for freedom, one person who knows everybody colors will guess correct and leave.
    this will continue if the outsider keeps telling he saw someone with XX color eyes.

  3. It is an island so there has to be water. No need for mirror. They can see their reflection in the water. LOL :P

  4. Count every colour u see then you would knw yours, since they have equal numbers.
