So A B won as many games, C D won as many games, and E ranked fifth.
Let's assume that A won four games and scored eight points, then B can only win three games, which is unreasonable.
So A won three games and B won three games. Suppose A loses to C, and then B loses to A, so B wins CDE.
Then C D won two games each, so D can only win C E, and C won A E, so E lost all.
Only o points.
X stands for winning and O stands for losing.
Look from left to right.
- A-B-C-D-E
A - x-o-x-x
B-o - x-x-x
C-x-o - o-x
Dioo x x
Oh, oh, oh, oh.
Because AB is tied for first place, D is at least third.
Look at the watch
such as
- A-B-C-D-E
A - x-o-x-x
A won, B D E lost to C.
