Rajesh is the father-in-law of Neha, and Akash is the only son of Rajesh. In this simple blood relation question, how is Akash related to Neha?

Introduction / Context:
This is a straightforward blood relation question about in-laws. You are told that Rajesh is Neha's father-in-law and that Akash is the only son of Rajesh. The goal is to determine Akash's relationship with Neha. Such questions test whether you clearly understand terms like father-in-law and can infer who the spouse must be when only one son is mentioned.

Given Data / Assumptions:
• Rajesh is the father-in-law of Neha.• Father-in-law means father of one's spouse.• Akash is the only son of Rajesh.• Rajesh does not have any other sons besides Akash.• Standard monogamous family structure is assumed.

Concept / Approach:
If Rajesh is Neha's father-in-law, Neha must be married to Rajesh's son. Since Akash is explicitly given as the only son of Rajesh, there is only one candidate who can be Neha's husband: Akash. Therefore, Akash is related to Neha as her husband. The question is essentially a direct application of the definition of father-in-law and the uniqueness of the only son.

Step-by-Step Solution:
Step 1: Interpret father-in-law. Rajesh is the father-in-law of Neha, so he is the father of Neha's spouse.Step 2: Let Neha's spouse be S. Then S must be a child of Rajesh.Step 3: The question states that Akash is the only son of Rajesh.Step 4: Therefore, if Neha is married to Rajesh's son, that son has to be Akash, because there is no other son.Step 5: Hence Akash is Neha's husband.

Verification / Alternative check:
Imagine a small family: Rajesh at the top, with one son Akash. If Neha's father-in-law is Rajesh, she must be married to Rajesh's son. Since Akash is the only son, it is impossible for Neha to be married to anyone else and still have Rajesh as father-in-law. No other relationship, like father or brother-in-law, fits the provided description as cleanly as husband does. Therefore, the answer is unambiguous.

Why Other Options Are Wrong:
Wife: This would incorrectly reverse genders, as Akash is male and Neha is female.Son: Akash is the son of Rajesh, not the son of Neha.Father: Akash is in the same generation as Neha as her spouse, not in a parent generation above.Brother-in-law: A brother-in-law would be a brother of Neha's spouse or spouse of her sibling; here, Akash is the spouse himself.

Common Pitfalls:
The only common mistake here is overthinking and trying to find a more complex relationship than necessary. Some may temporarily confuse father-in-law with brother-in-law. Always remember that father-in-law is strictly the father of your spouse. Once you connect father-in-law to the only son, it becomes immediately clear that the son, Akash, must be the husband of Neha.

Final Answer:
Akash is the husband of Neha.
