"There are 1000 lockers for a new school and there are 1000 students. Each student gets a locker. The first student enters and opens all 1000 lockers. The second student closes the every second locker. The third student rearangges the locker. For example the 3 one was open, he would close it. Vice versa. Which lockers would be open?"

If he closes the open ones and opens the closed ones, there is still 50% of the lockers open ie 500.
