Rajaram's son's sister's mother is Ramani. Based on this information, how is Ramani related to Rajaram?

Introduction / Context:
This is a straightforward relation chain question: Rajaram's son's sister's mother is Ramani. You must follow the chain step by step and then decide whether Ramani is Rajaram's wife, sister, mother or some other relative. Such questions test your ability to keep track of intermediate relations like son's sister and then identify shared parents.

Given Data / Assumptions:

• Rajaram has a son. Let us call him S.
• S has a sister. This sister is another child of Rajaram and Rajaram's spouse.
• The mother of this sister is Ramani.
• We assume a typical nuclear family structure with Rajaram and Ramani as potential parents of the children.

Concept / Approach:
The key idea is that both a son and his sister are usually children of the same parents. If S is Rajaram's son and S has a sister, that sister is also Rajaram's child. The mother of Rajaram's children is Rajaram's wife. Since Ramani is described as the mother of the son's sister, and hence the mother of Rajaram's child, she must be Rajaram's wife.

Step-by-Step Solution:
Step 1: Let Rajaram's son be S. So S is a child of Rajaram.Step 2: S's sister is another child of Rajaram (same generation, same parents in standard reasoning puzzles).Step 3: The mother of S's sister is Ramani.Step 4: Since S's sister is also Rajaram's child, the mother of that child is Rajaram's spouse.Step 5: Therefore, Ramani is Rajaram's wife.

Verification / Alternative check:
Consider an example: Rajaram is married to Ramani. They have two children, a son S and a daughter D. S's sister is D. The mother of D is Ramani. This matches the description Rajaram's son's sister's mother is Ramani perfectly. If we try to assign Ramani as Rajaram's sister or mother instead, we would need another woman to act as the mother of his children, which would contradict the single mother implied by the question. So the only consistent role for Ramani is as Rajaram's wife.

Why Other Options Are Wrong:
Aunt or cousin would put Ramani in a collateral line, not as the direct parent of Rajaram's children.Sister would mean Ramani is in the same generation as Rajaram and not usually the mother of his children in the context provided.Mother would make her the grandmother of S, but the statement clearly calls her the mother of S's sister, not grandmother.

Common Pitfalls:
Candidates sometimes stop at son's sister and imagine a cousin or an aunt relation without following the final step to the mother. It is crucial to notice that the person being pointed to (Ramani) is the mother of Rajaram's child, and in these puzzles that almost always indicates the spouse of the father unless otherwise stated.

Final Answer:
Ramani is related to Rajaram as his Wife.
