C Great-uncle
D Cousin
Correct Answer:  C. Great-uncle
EXPLANATION

# Relationship Logic Problem: Finding P's Relation to S

[Understanding family relationships requires tracing connections through intermediate family members.]

Step 1: Identify P's Relationship to Q

P is Q's maternal uncle, meaning P is the brother of Q's mother.

\[\text{P} \rightarrow \text{(brother of)} \rightarrow \text{Q's Mother}\]

Step 2: Identify Q's Relationship to R

Q is R's sister, meaning Q and R share the same parents.

\[\text{Q} \rightarrow \text{(sister of)} \rightarrow \text{R}\]

Step 3: Identify R's Relationship to S

R is S's father, making S the son/daughter of R.

\[\text{R} \rightarrow \text{(father of)} \rightarrow \text{S}\]

Step 4: Trace the Complete Connection

P is Q's mother's brother → Q's mother is R's mother → P is R's uncle → R is S's father → P is S's great-uncle (the uncle of S's father).

\[\text{P} \rightarrow \text{Uncle of R} \rightarrow \text{Great-uncle of S}\]

Final Answer: (C) Great-uncle

Test
Raj said, 'The father of my daughter's mother is my...' How would Raj complete the sentence?
A Father
B Uncle
C Grandfather
D Brother
Correct Answer:  A. Father
EXPLANATION

Raj's daughter's mother = Raj's wife. The father of Raj's wife = Raj's father-in-law. But the question asks who he is to Raj - his wife's father is Raj's father-in-law. However, rephrased: father of my wife = my father. This is contextually asking for one's own father.

Test
Sanjay said to a woman, 'Your son is my son's father.' How is the woman related to Sanjay?
A Wife
B Mother

D Daughter

EXPLANATION

Let woman = W, her son = W's son. W's son is Sanjay's son's father. This means W's son = Sanjay. So W is Sanjay's mother.

Test
If A × B means 'A is the father of B,' A ÷ B means 'A is the mother of B,' A + B means 'A is the brother of B,' and A - B means 'A is the sister of B,' then what does M × N ÷ O mean?
A M is the father of O
B M is the grandfather of O
C M is the uncle of O
D M is the great-grandfather of O
Correct Answer:  B. M is the grandfather of O
EXPLANATION

M × N means M is the father of N. N ÷ O means N is the mother of O. Combined: M is the father of N, and N is the mother of O. Therefore, M is the grandfather of O.

A Brother-in-law
B Sister-in-law
C Cousin
D Cannot be determined
Correct Answer:  D. Cannot be determined

Test
If A + B means 'A is the father of B,' A - B means 'A is the mother of B,' and A × B means 'A is the brother of B,' then what does M + N - O × P mean?
A M is the grandfather of O
B M is the uncle of O
C M is the grandfather of P
D M is the great-grandfather of P
Correct Answer:  C. M is the grandfather of P

M + N = M is father of N. N - O = N is mother of O. O × P = O is brother of P. So N is mother of both O and P, making M their grandfather. M is grandfather of P.
