Blood Relations (Advanced)

• Solve family relationship puzzles using given clues.
• Trace relationships across generations (grandparents, parents, siblings, cousins, in-laws).
• Use relationship charts/family trees as a solving tool.

1. Common relationship terms: father's brother = uncle, mother's sister = aunt, brother's son = nephew, sister's daughter = niece.
2. Cousin = child of your uncle or aunt.
3. Build a simple family tree diagram while solving — write names/symbols and connect them with relationship labels as you read each clue.
4. Pay attention to gender clues ("she", "his", "her") to correctly assign relationships (e.g., "father's mother" is always grandmother, regardless of the pronoun used elsewhere).

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

A is B's father -> A is a parent of B.
B is C's sister -> B and C are siblings (same parents).
So A, being B's father, is also C's father.
Answer: A is C's father.

• Confusing "nephew" (brother's/sister's son) with "cousin" (uncle's/aunt's child).
• Forgetting to check gender when the puzzle depends on it (e.g., "father's sister" = aunt, always).
• Not drawing a simple diagram, which can cause errors in multi-step relationship chains.

• If P is Q's mother and Q is R's brother, how is P related to R?
• What do you call your father's brother's son?
