In a certain code language,
‘A + B’ means ‘A is the wife of B
‘A – B’ means ‘A is the sister of B’
‘A × B’ means ‘A is the mother of B’
‘A ÷ B’ means ‘A is the daughter of B’
Based on the above, how is O related to L if ‘O − M ÷ N + L’?

The correct answer is
Daughter

Explaining O's Relation to L

This question requires us to figure out the family relationship between two individuals, O and L, based on a coded set of rules. We need to carefully decode the given expression 'O − M ÷ N + L' using the provided definitions.

Understanding the Code Language Rules

The problem provides specific meanings for different mathematical symbols when used between individuals (A and B):

  • 'A + B' means ‘A is the wife of B’.
  • 'A – B’ means ‘A is the sister of B’.
  • 'A × B’ means ‘A is the mother of B’.
  • 'A ÷ B’ means ‘A is the daughter of B’.

These rules help us determine gender and familial connections.

Decoding the Expression Step-by-Step

Let's break down the expression 'O − M ÷ N + L' piece by piece:

  • 'O − M': Applying the rule 'A – B' means ‘A is the sister of B’, we find that 'O is the sister of M'. This tells us that O is female.
  • 'M ÷ N': Using the rule 'A ÷ B’ means ‘A is the daughter of B’, we get 'M is the daughter of N'. This tells us that M is female.
  • 'N + L': Following the rule 'A + B’ means ‘A is the wife of B’, this translates to 'N is the wife of L'. This indicates that N is female and, consequently, L must be male.

Determining O's Final Relation to L

Now we combine the decoded relationships to establish the connection between O and L:

  • From 'M ÷ N', we know M is the daughter of N.
  • From 'N + L', we know N is the wife of L. Since N and L are married, and M is N's daughter, M is also L's daughter.
  • From 'O − M', we know O is the sister of M.
  • Since O is the sister of M, and M is the daughter of L, it follows logically that O is also the daughter of L.

Therefore, based on the code language provided, O is the daughter of L.
