Solving the Blood Relation Puzzle

This question asks us to determine the relationship between two individuals, Brunda and Mohan, based on a statement made by Keerthana. Let's break down Keerthana's statement step by step to build the family tree.

Analyzing Keerthana's Statement

Keerthana says: ‘Jyothi’s father Revanth is the only son of my father-in-law Mohan. Brunda is Jyothi’s sister”.

Let's analyze the key parts:

• Keerthana's father-in-law is Mohan. This means Mohan is the father of Keerthana's spouse.
• Jyothi's father is Revanth.
• Revanth is the only son of Keerthana's father-in-law, Mohan.
• Brunda is Jyothi's sister.

Building the Family Tree

From the statement, we know that Mohan is Keerthana's father-in-law. This implies Keerthana is married to Mohan's son.

We are also told that Revanth is the only son of Mohan. Since Mohan has only one son, and Keerthana is married to Mohan's son, Revanth must be Keerthana's husband.

So, we have the following relationships:

• Mohan is the father of Revanth.
• Keerthana is the wife of Revanth (and daughter-in-law of Mohan).

Next, we know that Revanth is Jyothi's father. This means Jyothi is the daughter of Revanth and Keerthana.

Finally, Brunda is Jyothi's sister. This means Brunda is also the daughter of Revanth and Keerthana, and thus, also the daughter of Mohan's son.

Let's summarize the key relationships:

Determining Brunda's Relationship to Mohan

We need to find out how Brunda is related to Mohan.

We established that Revanth is Mohan's son.

We also established that Brunda is Revanth's daughter.

Therefore, Brunda is the daughter of Mohan's son. The daughter of a person's son is their granddaughter.

Thus, Brunda is Mohan's granddaughter.

Conclusion on Brunda and Mohan's Relationship

Based on the detailed analysis of Keerthana's statement and the construction of the family tree, Brunda is the daughter of Mohan's only son, Revanth. This makes Brunda Mohan's granddaughter.

Additional Information: Solving Blood Relation Questions

Blood relation questions are common in competitive exams. They test your ability to decipher relationships from given statements. Here are some tips for solving them effectively:

• Read the statement carefully and identify the key individuals involved.
• Break down complex statements into smaller, simpler parts.
• Start building a family tree diagram. Use symbols to represent different genders and relationships (e.g., a horizontal line for marriage, a vertical line for parent-child).
• Identify the 'connecting' person or relationship that links different parts of the statement. In this case, Revanth being Mohan's son and Jyothi's father was key.
• Work backwards or forwards from known relationships to find the unknown one.
• Be mindful of terms like 'only son' or 'only daughter', as they significantly restrict possibilities.
• Verify your final relationship against the original statement to ensure it fits.
