Evelyn, her brother, her daughter and her son are tennis players.
As a game of doubles is about to begin.
- Evelyn's brother is directly across the net from her daughter.
- Evelyn’s son is diagonally across the net from the worst player's sibling.
- The best player and the worst player are on the same side of the net.
Who is the best player?
From points 1 and 2 there are two possible court layouts.
D S
-----
B E
OR
D E
-----
B S
Where D = daughter, E = Evelyn, B = brother, S = son. and --- is the net.
In the first case, B must be the worst players sibling (from point 2), and therefore Evelyn is the worst. From point 3, B must be the best since he is next to Evelyn.
In the second case, D must be the worst players sibling(from point 2), and therefore S must be the worst player. Therefore B again, must be the best from point 3.
Therefore, Evelyn's Brother is the best player
