Alright — this is a classic logical relationship puzzle , and we’ll break it down clearly so it’s both fun and easy to follow.

Quick Scoop

🧩 Riddle:

“Introducing a man, a woman said: His mother is the only daughter of my father. How is the man related to the woman?”

Let’s solve it step-by-step.

Step 1: Analyze the statement

The woman is speaking.
She says:

“His mother is the only daughter of my father.”

Let’s restate that in a simpler way:

  • “My father” = the woman’s father.
  • “The only daughter of my father” = the woman herself (since she says the only daughter).

So we can replace that part with “me.” That means:

“His mother is me.”

Step 2: Meaning of the sentence

  • The man’s mother is the woman speaking.
    That automatically makes the man her son.

✅ Final Answer:

The man is the woman’s son.
