Difficulty: MediumBlood Relations

During an office gathering, a manager named Kiran introduces a visitor to a colleague by saying, "She is the only daughter of my spouse's mother-in-law." Based on this statement, how is the visitor related to Kiran?

  1. A
    Sister-in-law
  2. SisterAnswer
  3. C
    Wife
  4. D
    Cannot be determined

Answer

The visitor is Kiran's sister.
Breaking down the statement backwards: Kiran's 'spouse's mother-in-law' is Kiran's mother. The 'only daughter' of Kiran's mother is either Kiran herself (if female) or Kiran's sister (if male). Because Kiran is introducing a distinct third person ('She is'), the visitor cannot be Kiran. Thus, Kiran must be male, and the visitor is his sister.

Step-by-Step Solution

1
Identify the relationship described by 'my spouse's mother-in-law'.
Kiran's spouse's mother-in-law is Kiran's own mother.
In a marital relationship, the mother-in-law of one spouse is the biological mother of the other spouse.
2
Determine the identity of 'the only daughter' of Kiran's mother.
The only daughter of Kiran's mother must either be Kiran herself (if Kiran is female) or Kiran's sister (if Kiran is male).
The child of one's mother is one's sibling, or oneself.
3
Deduce Kiran's gender from the contextual clues.
Since Kiran is introducing the visitor as a separate third party ('She is...'), the visitor cannot be Kiran herself. Therefore, Kiran must be male, and the visitor is his sister.
A person cannot logically introduce themselves as a distinct visitor in this manner, eliminating the ambiguity.
