Beyond the Answer

Let’s start by defining the number of students who play Hockey as and the number of students who play Football as . According to the information provided, we have two equations to work with.
  1. The total number of students playing either game is given by:
    This accounts for the 15 students who play both games.
  2. The number of students who play Football is five more than twice the number that play Hockey:
Now, we can substitute the second equation into the first:
Now simplifying this:
We found that 30 students play Hockey. Now, substituting back into the second equation to find :
Thus, the number of students that play Football is 65.
In summary:
(i) The number of students that play Football is 65.
(ii) The number of students that play Hockey is 30.
