Four married
couples played a tennis tournament of ‘mixed doubles’. A man and a woman always
played against a man and a woman. However, no person ever played with or
against any other person more than once. They all played together n two courts
on three successive days.
Can you show how they could have done it?
Answer: Let’s
call the men A B C D and their wives E F G H. They must play in such a way that
no person ever plays twice with or against another person.
First Court second Court
1st day AD against
BF CE against DF
2nd day AH against
CF DE against BH
3rd day AF against
DG BE against CH
In this way no man ever plays with or against his own/ wife.
