The questions wordings seem much different from what solutions have been posted.
Had it been factors, it is understandable.
"How many different positive even divisors does n have, including n"
This can totally mean distinct values, for all its wordings is concerned.

You’re mistaken here. The question is only asking about the even divisors of a single n = 4p, not about all possible values across different choices of p. For any prime p > 2, n will always have exactly 4 even divisors: 2, 4, 2p, and 4p. If it were interpreted the way you suggest, then the answer would be infinitely many, since p can take infinitely many prime values and each would produce new divisors.

The main issue I had to tackle was the scope of the question, we had P=3 as our one solution, but i was not sure about other prime numbers, that if we put them, would we still get 4 even divisors.
Anyone has any kind of tip that how to determine the scope, or extent to which we put put values to find out the solution?
