Q. Pointing a photograph, a man said, “I have no brother and sister but the father of that man is the son of my father”. Whose photograph is it?
a) His son’s
b) His own
c) His father’s
d) His nephew’s
Correct Answer: a) His son’s
Question from UPPSC Prelims CSAT 2025
Explanation:
Let the speaker be M. He says, “I have no brother and sister,” meaning he has no siblings (only child). He also says, “the father of that man is the son of my father.” Since M has no siblings, “the son of my father” can only be M himself.
Therefore, the father of the man in the photograph is M, implying the photograph is of M’s son.
