DFM Challenges 03

Problem 1: Strikers

It was the 2017 season when Rovers won the league with that fabulous striking trio of McAnish, McBurnie and McClure scoring all the goals. How many did they score? Well,

  • McAnish and McBurnie scored 48 between them,
  • McBurnie and McClure scored 43 between them,
  • McClure and McAnish scored 57 between them.

That should be enough information to discover how many goals the strikers scored individually. Can you work it out? Explain your answer carefully.
