Family Relationship Puzzle Solution

This solution deciphers the relationship between Po and Ko based on the provided coding rules and expression.

Understanding Relationship Codes

  • $Mo > No$: Mo is the daughter of No (No is a parent).
  • $Mo # No$: Mo is the father of No (Mo is male).
  • $Mo $ No$: Mo is the mother of No (Mo is female).
  • $Mo / No$: Mo is the brother of No (Mo is male).

Decoding the Expression: $Po $ Qo # Ro / To > Ko$

We break down the expression step-by-step:

  1. $Po $ Qo$: This means Po is the mother of Qo. Po is female.
  2. $Qo # Ro$: This means Qo is the father of Ro. Qo is male.
  3. $Ro / To$: This means Ro is the brother of To. Ro is male.
  4. $To > Ko$: This means To is the daughter of Ko. To is female. Ko is a parent.

Determining the Relationship between Po and Ko

Let's combine the deductions:

  • From $Qo # Ro$ and $Ro / To$, we know Qo is the father of Ro, and Ro is the brother of To. Therefore, Qo is the father of To.
  • From $To > Ko$, we know Ko is the parent of To. Since Qo is the father of To, Ko must be the mother of To. This establishes Ko as female.
  • As Qo is the father of To and Ko is the mother of To, Qo and Ko are married, making Qo the husband of Ko.
  • From $Po $ Qo$, Po is the mother of Qo.
  • Since Po is the mother of Qo, and Qo is the husband of Ko, Po is the mother of Ko's husband.
  • This directly implies that Po is Ko's mother-in-law.

Matching with Options

The relationship 'mother-in-law' corresponds to 'Husband's mother' from Ko's perspective. Therefore, Po is related to Ko as her Husband's mother.
