In the following football table and addition sum letters have been substituted for digits (from 0 to 9). The same letter stands for the same digit wherever it appears and different letters stand for different digits.

The three teams are eventually going to play each other once — or perhaps they have already done so.

(Two points are given for a win and one point to each size in a drawn match).

Find the scores in the football matches and write the addition sum out with numbers substituted for letters.

A similar problem to

Enigma 7.This Python program uses the

Football.substituted_table*()andSubstitutedSum()solvers from theenigma.pylibrary, both written to make solving such problems less tedious. It runs in 42ms.Solution:The scores in the matches are: A vs B = 5-0; A vs C = 3-3; B vs C = 0-4. The addition sum is 10 + 70 = 80.
