Decoding the Coding Language Relationship Puzzle

This question involves deciphering relationships based on a specific code language. We need to determine how 'L' is related to 'O' by analyzing the given coded statement: 'K & L & M # N @ O'.

Understanding the Coding Rules

Let's first establish the meaning of each symbol used in the code:

  • 'M & N' means 'M is the mother of N'. This implies M is Female (represented as $F$).
  • 'M @ N' means 'M is the son of N'. This implies M is Male (represented as $M$).
  • 'M # N' means 'M is the daughter of N'. This implies M is Female (represented as $F$).

Analyzing the Relationship Chain Step-by-Step

Now, let's break down the given chain 'K & L & M # N @ O' element by element:

  1. K & L: According to the rule, K is the mother of L.
    • Relationship: K is mother of L.
    • Gender Implication: K is Female ($F$).
  2. L & M: According to the rule, L is the mother of M.
    • Relationship: L is mother of M.
    • Gender Implication: L is Female ($F$).

    Combining these steps: K is the mother of L, and L is the mother of M. Thus, K is the maternal grandmother of M.

  3. M # N: According to the rule, M is the daughter of N.
    • Relationship: M is daughter of N.
    • Gender Implication: M is Female ($F$).

    Since L is the mother of M, and N is also a parent of M, N must be the father of M. Therefore, N is Male ($M$).

  4. N @ O: According to the rule, N is the son of O.
    • Relationship: N is son of O.
    • Gender Implication: N is Male ($M$).

    This statement indicates that O is a parent of N. O's gender is not specified here.

Establishing the Connection between L and O

Let's combine the deduced relationships to find how L is connected to O:

  • From step 2, L is the mother of M.
  • From step 3, N is the father of M.
  • Since L is the mother and N is the father of M, L must be the wife of N.
  • From step 4, N is the son of O.
  • Therefore, L is the wife of O's son.

Final Relationship Determination

The relationship 'wife of a son' is commonly referred to as 'daughter-in-law'. Based on the options provided, the correct description is 'Son's wife'.
