This solution was submitted by Wymondham High School who reasoned their solution in the following way:
To start off we tried to work out the logical answers. For example where it says 'D had no points', it was obvious they had neither a win or a draw.
Then we found out that 'For' and 'Against' columns must add up to the same number. In the end we put 4 in the 'For' column and 2 in the 'Against' column.
At one point we worked out the results to each match. These were:
|A v B||0 - 2||B v C||2 - 2||C v D||not played|
|A v C||2 - 2||B v D||1 - 0|
|A v D||2 - 0|
Here is the finished table of results:
