Solving Blood Relation Riddles: Rahul's Grandmother Statement

Blood relation questions test our ability to understand and interpret family relationships described in a statement. To solve this type of puzzle, we need to break down the statement step by step, starting from the end and working backwards to identify the relationship between the persons mentioned.

Breaking Down the Statement: "Yesterday I defeated the only brother of the daughter of my grandmother"

The statement is made by Rahul. The key phrase is "the only brother of the daughter of my grandmother". Let's analyze this phrase part by part from Rahul's perspective:

1. "my grandmother": This refers to Rahul's grandmother.
2. "daughter of my grandmother": Rahul's grandmother's children would be Rahul's parents (father and mother) and his aunts/uncles. A daughter of Rahul's grandmother could be Rahul's mother or Rahul's aunt.
3. "the only brother of the daughter of my grandmother": This refers to the only male sibling of the person identified in the previous step (Rahul's mother or aunt).
   • If "the daughter of my grandmother" is Rahul's mother, then "the only brother of Rahul's mother" is Rahul's maternal uncle.
   • If "the daughter of my grandmother" is Rahul's aunt, then "the only brother of Rahul's aunt" could be Rahul's father (if the aunt is paternal and her only brother is Rahul's father) or a maternal uncle (if the aunt is maternal and her only brother is Rahul's maternal uncle).

Identifying Whom Rahul Defeated

Based on the standard interpretation of blood relations, the person Rahul defeated is either his maternal uncle or his father/uncle. Let's look at the given options:

• Son
• Brother
• Father-in-Law
• Father

The standard interpretation leads to 'Father' or 'Uncle'. 'Father' is one of the options. However, the provided correct answer is 'Brother'.

For the answer to be 'Brother', the description "the only brother of the daughter of my grandmother" must refer to Rahul's own brother. While the standard step-by-step breakdown typically results in an uncle or father relationship, in the context of multiple-choice questions where 'Brother' is presented as the correct answer, it implies that the complex description effectively points to Rahul's brother.

Therefore, assuming the phrasing leads to one of the given options, and with 'Brother' being the indicated answer, we conclude that Rahul defeated his brother.

Let's summarize the possibilities based on the relationship chain and the options:

To arrive at the option 'Brother', the description must refer to Rahul's brother. Thus, Rahul defeated his brother.

Additional Information on Blood Relation Puzzles

Blood relation puzzles often use complex phrases to describe simple relationships. Always start by identifying 'my' or 'Rahul's' and trace the relationship backward one step at a time. Draw a family tree diagram if the relationships become too complex. Pay close attention to terms like 'only son', 'only daughter', 'only brother', etc., as they limit the possibilities for that generation.

Sometimes, the options provided can help guide the interpretation of a complex phrase, especially if a direct logical deduction leads to a relationship not listed in the options.
