Understanding Blood Relation Puzzles
This question is a classic example of a blood relation puzzle. To solve it, we need to carefully decode the statement made by Kumar, breaking it down phrase by phrase to establish the connections between the individuals mentioned.
Analyzing Kumar's Statement Step-by-Step
Kumar says, “He is the son of my sister’s father - in - law’s wife Sushma.”
Let's dissect this statement from the end, starting with Kumar:
- "my sister": This refers to Kumar's sister.
- "my sister's father - in - law": The father-in-law of Kumar's sister is the father of her husband. So, this person is the father of Kumar's sister's husband.
- "my sister's father - in - law's wife": The wife of Kumar's sister's father-in-law is the mother of Kumar's sister's husband.
- The statement identifies this person as Sushma. So, Sushma is the mother of Kumar's sister's husband.
- The statement says, "He is the son of ... Sushma.": The person in the photograph is a son of Sushma.
Connecting the Relations and Finding the Person
We know Sushma is the mother of Kumar's sister's husband.
We also know that the person in the photograph is a son of Sushma.
The question provides a crucial piece of information: "Sushma has only one son."
Since Sushma has only one son, and she is the mother of Kumar's sister's husband, her only son must be Kumar's sister's husband.
Therefore, the person in the photograph, being the only son of Sushma, is Kumar's sister's husband.
