He has 5 children, 4 daughters, and a son, who is a brother to all of Harry's daughters.

He has 5 children, 4 daughters, and a son, who is a brother to all of Harry's daughters.

My reasoning:

Four daughters and each had a brother. The number of daughters does not means that each has a separate brother.

So, let b = 1 brother in the family

Let H = Harry

H = 4 + b

H = 4 + 1

H = 5

BTW, math only when time allows. I am desperately seeking to move out. I miss Cohen and daily math solving but life plus the fear of COVID-19 has paralyzed my life. I also may be let go from the job. You can understand how difficult life has become for me (and the world).

According to my friend Alice, the answer is not 5.

What is her reasoning?

I do agree there could be other answers. For example, suppose Harry had his 4 daughters with multiple women, and we make the distinction between full and half brothers, etc.

She said to look at the tenses.

Here is what I found online:

The main focus are on the verbs : “had” and “have”

He had four daughters and each daughter had a brother ,that makes it 4+1 = 5 children altogether that he once had.Perhaps some unfortunate event claimed the lives of the four daughters including their single brother,based on the past tense “had”. This means that at present,he has no children.
Similarly ,considering the verb : “have” which is at present tense form,he has no single child.Therefore, the answer is zero,that is 0.

If the author of the problem intended it to be about verb tense, then it's a nonsensical problem in my opinion. I've seen variants of this riddle before, and the reasoning I originally posted was always what was intended.

We were right. The answer is 5.
