Difficulty: MediumBlood Relations

In a cryptographic family ledger, relational links between individuals are denoted by specific symbols:

P@QP @ Q means PP is the father of QQ.
P#QP \# Q means PP is the wife of QQ.
P$QP \$ Q means PP is the brother of QQ.
P%QP \% Q means PP is the daughter of QQ.

Based on the coded expression Aditi%Meera#Dev$Shashi\text{Aditi} \% \text{Meera} \# \text{Dev} \$ \text{Shashi}, what is the exact relationship of Shashi to Aditi?

  1. A
    Paternal Uncle
  2. B
    Paternal Aunt
  3. C
    Niece
  4. Data is insufficient to determineAnswer

Answer

Data is insufficient to determine
The relationship chain establishes that Shashi is the sibling of Aditi's father. However, the expression does not provide a relational symbol that defines Shashi's gender. Without knowing if Shashi is a man or a woman, the exact relationship (Paternal Uncle or Paternal Aunt) cannot be determined. Therefore, the data is insufficient.

Step-by-Step Solution

1
Analyze the first part of the expression: Aditi%Meera\text{Aditi} \% \text{Meera}
Aditi is the daughter of Meera. (Aditi is female).
Applies the defined rule for the %\% symbol.
2
Analyze the next part: Meera#Dev\text{Meera} \# \text{Dev}
Meera is the wife of Dev. Therefore, Dev is male and is the father of Aditi.
Applies the rule for the #\# symbol and establishes the parental link.
3
Analyze the final part: Dev$Shashi\text{Dev} \$ \text{Shashi}
Dev is the brother of Shashi. This makes Shashi the sibling of Aditi's father.
Applies the rule for the $\$ symbol.
4
Evaluate Shashi's gender to determine the precise relationship.
The symbol $\$ defines Dev as a male brother, but it does not specify whether the sibling (Shashi) is male or female.
Logical constraints require explicit proof of gender. Proper names cannot be used to deduce gender in blood relation puzzles.
