A man is looking at a picture of someone. His friend asks, "Who is it you are looking at?" The man replies, "Brothers and sisters I have none, but that man's father is my father's son." The question is: Who is in the picture?

Objective:
Determine the identity of the person in the picture based on the man's statement.

Solution

To solve this riddle, we need to carefully analyze the man's statement and break it down logically.

Step-by-Step Solution for The Two Sons Riddle:

Step 1: Break Down the Statement

The man says, "Brothers and sisters I have none, but that man's father is my father's son."

• "Brothers and sisters I have none": This means the man has no siblings.
• "That man's father": The person in the picture has a father.
• "Is my father's son": The key part of the riddle. Since the man has no siblings, "my father's son" must refer to the man himself.

Step 2: Interpret the Statement

Given that "my father's son" refers to the man himself, the statement can be rephrased as:

• "That man's father is me."

This means that the man is looking at a picture of someone whose father is the man himself.

Step 3: Identify the Person in the Picture

If the man's statement implies that "I am the father of the person in the picture," then the person in the picture must be his son.

Final Answer

The person in the picture is the man's son.
