Understanding Blood Relations: Solving the Puzzle
Blood relation questions test your ability to decipher relationships based on given statements. To solve this type of problem, it is helpful to break down the statement step-by-step and identify the individuals involved and their connections.
The statement given by Rohit to Ruchi is: “Your mother’s father is the father-in-law of my son”.
Let's analyze the statement from Ruchi's perspective first, then from Rohit's perspective, and finally connect the two parts.
Analyzing Ruchi's Relation
- “Your mother’s father” refers to Ruchi’s maternal grandfather.
Analyzing Rohit's Relation
- “my son” refers to Rohit's son.
- “the father-in-law of my son” means the father of Rohit's son's wife.
Connecting the Relations
The statement connects these two parts:
Ruchi’s maternal grandfather = The father of Rohit's son's wife.
Let's trace this from Rohit's side:
- Rohit has a son.
- Rohit's son has a wife.
- The wife's father is the father-in-law of Rohit's son.
So, Ruchi's maternal grandfather is the father of Rohit's son's wife.
This implies that Ruchi's mother is Rohit's son's wife (since the father of Ruchi's mother is also the father of Rohit's son's wife).
Now, let's see how Ruchi is related to Rohit based on this:
- Ruchi's mother is Rohit's son's wife.
- This means Ruchi's mother is Rohit's daughter-in-law.
- If Ruchi's mother is Rohit's daughter-in-law, then Ruchi is the daughter of Rohit's son.
- A daughter of one's son is their granddaughter.
Therefore, Ruchi is Rohit's granddaughter.
Conclusion: Ruchi's Relationship to Rohit
Based on the detailed analysis of the statement, Ruchi is the granddaughter of Rohit.

Additional Information on Blood Relation Puzzles
