Pointing to a man's photograph, Rahul said: "His brother's father is the only son of my grandfather."
How is the man in the photograph related to Rahul?
Explanation
Step 1: Analyze Rahul's Side of the Family
Look at the second part of Rahul's statement:
"...the only son of my grandfather."
Rahul's grandfather's only son must be Rahul's Father.
Let this person be represented as F. Thus:
Only son of grandfather=F (Rahul’s Father)
Step 2: Analyze the Photograph Man's Side of the Family
Look at the first part of Rahul's statement:
"His brother's father..."
The father of the man's brother is also the father of the man himself.
Let the man in the photograph be represented as M. Thus:
His brother’s father=Father of M
Step 3: Establish the Relationship
Now, equate both sides based on the full statement ("His brother's father is the only son of my grandfather"):
Father of M=F (Rahul’s Father)
Since the man in the photograph (M) and Rahul share the same father (F), they are siblings.
Therefore, the man in the photograph is Rahul's Brother.
Correct Answer:
(b) Brother
