Question

Rahul said, “My father’s sister’s husband is the only son of Mary’s grandfather.” How is Mary related to Rahul?

• A. Sister
• B. Cousin
• C. Niece
• D. Aunt

Hint:

In nested descriptions like “X’s father’s sister’s husband…”, move stepwise from the inner noun outward, renaming each link (aunt, uncle, etc.), then connect to the other person.

Answer 1

The Correct Option is B

Step 1 (Translate each relation).
Rahul’s father’s sister = Rahul’s paternal aunt.
Her husband = Rahul’s uncle (by marriage).
Step 2 (Use the clause about Mary).
That same man is “the only son of Mary’s grandfather” he is Mary’s father.
Step 3 (Link Rahul and Mary).
So, Mary’s father = Rahul’s uncle (by marriage).
If Mary’s father is Rahul’s uncle, then Mary is Rahul’s cousin.
\[ {\text{Cousin (Option (b)}} \]
