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?

This is a great riddle. It makes you think. There are 600 blinds open after all 1000 Grundos complete the process.

One blind is open. The first one doesn't get touched again after the first Grundos opens it.
