i got 11 for my answear when i did this

Answer 5

Well as the key says...you know that

4 | 1 would stand for 41 ...

so the 45 would be

4 | 5

Now you want all the people that would be larger than 4 | 5 so you would look at everything bigger than that...for example 4|8 is one..because that's 48

So we have

4 | 8
5 | 0
5 | 0
5 | 1
5 | 5
5 | 6
6 | 2
6 | 4
6 | 5
6 | 5
7 | 3

Looks like 11 to me
