Worked practice questions

Pointing to a photograph, Rohan said: 'She is my mother's only daughter's daughter.' How is the girl related to Rohan?

  1. Niece
  2. Cousin
  3. Sister
  4. Daughter
Show answer and solution

Correct answer: A. Niece

Mother's only daughter = Rohan's sister (assuming Rohan is male; the only daughter of his mother). That sister's daughter = Rohan's niece. (If Rohan is female and is the only daughter, then 'daughter' would be the answer — but typically 'mother's only daughter' refers to someone else if the speaker is male.)

A is B's father. C is A's son. D is B's only sister. How is C related to D?

  1. Cousin
  2. Brother
  3. Nephew
  4. Uncle
Show answer and solution

Correct answer: B. Brother

A is B's father. C is A's son → C and B are siblings. D is B's only sister → D is also A's daughter (i.e., another sibling of B and C). **Therefore C is brother to D.**

In a family, P is M's son. N is P's sister. Q is M's mother. How is Q related to N?

  1. Mother
  2. Aunt
  3. Sister
  4. Grandmother
Show answer and solution

Correct answer: D. Grandmother

M's son = P, so M is P's father/mother. N is P's sister, so N is also M's child. Q is M's mother. **Therefore Q is N's grandmother.**
