    'This mans father is my fathers son' puzzle.

    A man, pointing to a portrait, exclaimed, I have no sisters or brothers, but that man's father is my father's son.

    The man whose portrait he was looking at was:
    A) His father
    B) His son
    C) Himself
    D) His uncle


    Please detail how you deduced the answer! What was your methodology?

    But OP. Look at this logically.

    The 'my fathers son' part obviously is himself.

    So rewrite the statement as.

    That mans father is me.

    So it's his son!

    He wouldn't have a chance of being a nephew ?
    Someone with no brothers may previously have had one.
