Let the number of pupils in Floorball be x.
Then the number of pupils in Tennis will be (x + 8).
The total number of pupils in the three CCAs is 42 + 42 + x.
This can be represented as 2(42) + x = 84 + x.
Solving for x, we get:
2(42) + x = 84 + x
84 + x = 84 + x
x = 42
Therefore, there are 42 pupils in Floorball and 42 + 8 = 50 pupils in Tennis.
