In a certain code language,

‘A+ B’ means ‘A is the father of B’

‘A – B’ means ‘B is the sister of A’

‘A x B’ means ‘A is the wife of B’

‘A ÷ B’ means ‘A is the mother of B’

Based on the above, how is L related to K if ‘N x M − K ÷ L + P’?

The correct answer is Son.

To determine how L is related to K in the given expression, we decode the relations step-by-step from left to right using the rules provided:

1. ‘A+ B’ means ‘A is the father of B’
2. ‘A – B’ means ‘B is the sister of A’
3. ‘A x B’ means ‘A is the wife of B’
4. ‘A ÷ B’ means ‘A is the mother of B’

Let's analyze the expression ‘N x M − K ÷ L + P’:
- N x M: Since ‘A x B’ means ‘A is the wife of B’, N is the wife of M. This implies M is a male (husband) and N is a female (wife).
- M − K: Since ‘A – B’ means ‘B is the sister of A’, K is the sister of M. This implies K is a female.
- K ÷ L: Since ‘A ÷ B’ means ‘A is the mother of B’, K is the mother of L. Since K is female, this fits perfectly.
- L + P: Since ‘A+ B’ means ‘A is the father of B’, L is the father of P. This implies L is a male.

Now, let's trace the relationship between L and K:
- We know that K is the mother of L (from K ÷ L).
- Since L is the father of P (from L + P), L must be male.
- Therefore, since K is the mother of L and L is male, L is the son of K.
