18. At my last Scrabble tournament every player played one game against everybody else (games are always played one-against-one). The total number of games that oldies played between themselves exceeded those played between oldies and youngsters by 18. There were 4 youngsters at the tournament, so how many games were played in total? 120 games were played. See workings below.
19. What connection links these pictures: The four sisters from Little Women (Jo, Amy, Beth & Meg)
20. Unscramble the two words : A C D L M N O S U Y MANY CLOUDS (the Grand National winner)
Maths workings:
Totally 120 games were played in the tournament.
Let N be the number of oldies in the tournament.
Then the number of games played by oldies between themselves
= N*(N-1)/2
The number of games played by oldies with youngsters = 4*N
(since there were 4 youngsters in the tournament)
It is given that the total number of games that oldies played between themselves exceeded those played by oldies with youngsters by 18.
Hence
N*(N-1)/2 - 4*N = 18
N*(N-1) - 8*N = 36
N*N - N - 8*N = 36
N^2 - 9*N - 36 = 0
Factorizing we get,
N^2 - 12*N + 3*N - 36 = 0
N*(N - 12) + 3*(N - 12) = 0
(N - 12)(N + 3) = 0
Hence N = 12 or -3 (not possible).
Hence the number of oldies in the chess tournament
= N = 12
Therefore the total number of people participating in the chess tournament = 12 + 4 = 16.
The total number of games played in the tournament
= T*(T-1)/2
= 16*15/2
= 120
