ANSWER: His son
The key to solving the riddle lies in understanding the relationships described in the statement. Let’s break it down step by step:
“Brothers & Sisters, I have none”: This part indicates that the man speaking does not have any siblings.
“But that man’s father is my father’s son”: Here, the term “that man’s father” refers to the father of the person in the photograph. On the other hand, “my father’s son” refers to the man himself, as he is the son of his own father.
Putting these two parts together, we can deduce that the person in the photograph is the son of the man who is speaking. In other words, the man in the photograph is the man’s son.
So, to answer the question posed by his friend about who is in the photograph, the man would say: “That man in the photograph is my son.”
