In The Dudeney Stakes at the local racecourse, six horses were rather special. A bookie, Isaac Conway, told me how much, in pence, he had taken on each of the six (less than £500 on each). But he translated the totals using a letter-for-digit substitution and the six figures were FIRST, THIRD, FIFTH, SIXTH, NINTH and TENTH, which happened to correspond to their positions in the race! Isaac also told me the total amount taken on the horses finishing first and third equalled that taken on the sixth.
How much did he take on the tenth?
