This is part of the "conundrum" game on a virtual pets site I play. I need some help figuring it out! You don't need to know who "Dr. Sloth" is or what "Virtupets" or "Grundos" are. :^) All help is appreciated as this has me totally stumped! The riddle is as follows:
"In an exceptionally long corridor in the Virtupets Space Station, there are one thousand windows along one wall. Coincidentally, there are exactly one thousand Grundos in the station. Dr Sloth orders the first Grundo to open the blinds on every window. Then, he orders the second Grundo to close the blinds on every second window. Then the third Grundo is told to go to every third window, and close the blinds if they are open, and open the blinds if they are closed. The fourth Grundo does this for every fourth window, and so on.
After all 1000 Grundos complete the process, how many blinds are open?"
