Solving the Blood Relation Puzzle: Nirmala and Radha

Let's break down the given statement to understand the relationship between Nirmala and Radha.

The key statement is: "The mother of Radha is the only daughter of Nirmala's father."

We are also given an important condition: "If Nirmala is the only child of their parent".

Consider Nirmala's father. Let's call him Person X.
The statement says "the only daughter of Nirmala's father".
Since Nirmala is the only child, she must be the only daughter (or son, if she were a son, but the phrase 'daughter' specifies gender) of her father.
Therefore, "the only daughter of Nirmala's father" is Nirmala herself.

Now substitute this back into the original statement:

"The mother of Radha is [the only daughter of Nirmala's father]"

Becomes:

"The mother of Radha is Nirmala"

If Nirmala is the mother of Radha, then Nirmala is related to Radha as her mother.

Sister: This is incorrect, as Nirmala is Radha's mother.
Mother: This matches our conclusion.
Aunt: This is incorrect.
Can't determine: We were able to determine the relationship based on the provided information.

Thus, Nirmala is the mother of Radha.
