5. Which one is odd one out?
It is the only one that does not have an identical match.

6. In a game of eight players lasting for 90 minutes, four reserves alternate equally with each player. This means that all players, including the reserves, are on the pitch for exactly the same length of time. For how long is each player on the pitch?
60 minutes.
Total time for 8 players = 8 ×90 = 720 minutes.
However, as 12 people (8 + 4)are on the pitch an equal length of time, they are each on the pitch for 60 minutes (720 ÷ 12).
