Question

Pointing to a photograph, Mrs. Riya said, “He is the son of the only daughter of my grandfather’s only son.” How is the boy in the photograph related to Mrs. Riya?

• A. Brother
• B. Cousin
• C. Nephew
• D. Son

Hint:

Always identify yourself as the speaker. "Grandfather's only son's only daughter" is a classic phrasing used in exams to describe the speaker themselves.

Answer 1

The Correct Option is D

Step 1: Identify "my grandfather's only son."
Mrs. Riya is speaking; her grandfather's only son = Riya's father (since the grandfather has only one son, that son must be Riya's father).
Step 2: Identify "the only daughter of my grandfather's only son."
The only daughter of Riya's father = Riya herself (since Riya is the only daughter of her father); so the person described so far = son of Riya.
Step 3: Determine the final relationship.
"He is the son of the only daughter of my grandfather's only son" means He is the son of Riya; therefore the boy being referred to is Riya's own Son.
\[ \boxed{\text{Son}} \]
