Some married couples (including my husband and me) entered a “round-robin” squash tournament at our local club. In such a tournament each individual plays each of the others once.
At the end of the tournament my husband had won a prime number of games and so had I. As you might expect, women did much better than men: the number of games won by the worst-performing female was over three times the number of games won by the best-performing male.
How many married couples entered the tournament? In how many games did a man beat a woman?
