Questions 20-22
A company owns exactly five delivery vans designated K, L, M, N, and O. At the end of the day, each of the vans must be parked in one of three parking lanes numbered 1, 2, and 3, which are each wide enough for just one van and long enough for all five vans. In lane 1, only vans K and L can be parked, but neither of these vans has to be parked in that lane.

No driver parks behind any more of the other vans than he has to at the time.
