Think of it this way
Let's just say you had 3 girls and 1 boy
So let's say all the girls had 17 points each, that gives them an average of 17

So that means that to get the average of the 1 boy you do $$(17+17+17+x)\div4=16$$ the x is the number of points the boy got because you don't know how much he got

Solve for the x

Oh my bad I'm so sorry I got the numbers mixed up
The 17's should be 18's and the 16 should be 17

SO anyway for whatever answer you get is always the same no matter how many boys and girls you have because average are always the same if you scale up the number of data
