Understanding Family Relationships: T and Q

This explanation breaks down the family tree based on the clues provided to determine how T is related to Q.

Analyzing the Family Clues

Let's analyze each piece of information step by step:

• G's Children: G is the father of L, and L is G's only son. This means L is male.
• G and T's Connection: G is the father-in-law of T. This means G is the father of T's spouse. Since L is the only son of G, it implies that L is married to T.
• T's Children: T is the mother of P. This confirms that T is female. T also has only one son.
• Siblings P and Q: P and Q are siblings. This means they share the same parents. Their parents are T and L.
• Q's Identity: Q is not the granddaughter of G. Since L (G's son) is married to T (female), their children (P and Q) are G's grandchildren. If Q were female, Q would be G's granddaughter. Because the clue states Q is *not* the granddaughter, Q must be male. This means Q is G's grandson, which aligns with T having only one son (Q).

Determining T's Relationship to Q

Based on the analysis above:

• T is the mother of P.
• P and Q are siblings.
• Therefore, T is the parent of both P and Q.
• Since we know T is female (the mother), T is the mother of Q.

Conclusion on T's Relation

Following the logical deduction from the given statements, T is the mother of Q.
