Four people, Q, R, S and T, compete in a round robin tournament, playing one game against each of the other three.
Each player scores only when a player that he defeats, beats another player. (For example, A beats B and B beats C and D. A receives 2 points because B won two games. Note that A does not get a point for beating B.)
- No one won all three of his games.
- No one lost all three of his games.
- Q won the tournament by scoring the most points.
- S came in last by scoring 1 point and winning the smallest number of games.
- T beat Q.
- The most points scored was 3.
