Question 106460: A school has 1000 lockers that are closed. A person passes through and closes every other locker starting with locker 2. Another person passes through, changing every 3rd locker (opening it if it is closed or closing it if it was open) starting with locker 3. This continues until 1000 people pass through. At the end of the process which locker numbers are closed? Answer by solver91311(24713) (Show Source):
You can put this solution on YOUR website! Can't do this one. Either the lockers were all open in the first place, or the 2nd person to pass through opened every other closed locker rather than closing every other locker as your version of the problem states. Resend this one and I'll work on it.
