Pointing to a man, a woman said, 'His mother is the only daughter of my father'. How is the man related to the woman?
Brother
Son
Father
Uncle
Son
Work backwards from the speaker. The only daughter of a speaker's father (when the speaker is female) is the speaker herself.
Work backwards from the speaker. The only daughter of a speaker's father (when the speaker is female) is the speaker herself.
Step 1: Simplify the inner phrase
Analyze the phrase 'my father's only daughter'. Since the speaker is a woman, her father's only daughter is the woman herself.
Step 2: Substitute and establish relation
Substitute this back into the original statement: 'His mother is the woman herself'. Therefore, the man is the son of the woman.
A: Brother is wrong because the woman is the man's mother, not his sibling. C: Father is wrong because the direct relation established is mother and son. D: Uncle is wrong because the man is in the immediate next generation as her son.
B is correct because the only daughter of the speaker's father is the speaker herself, which means the man's mother is the woman speaking, making him her son.
For blood relation questions containing phrases like 'only son' or 'only daughter', always evaluate the speaker's gender first to immediately decode who the relative refers to.
