In a certain code language,
'A + B' means 'A is the son of B',
'A - B' means 'A is the brother of B',
'A × B' means 'A is the wife of B',
'A ÷ B' means 'A is the daughter of B'.
Based on the above, how is L related to M if 'L - N ÷ O × M + P'?
- AFather's father
- BBrother
- CSon
- DFather
Solution & Step-by-step Explanation
Let's decode the expression 'L - N ÷ O × M + P' piece by piece:
L - N: L is the brother of N (L[+]→N).
N ÷ O: N is the daughter of O (N[−] is the daughter of O). Since L is N's brother, L is also the child of O.
O × M: O is the wife of M (O[−] is married to M[+]). This means M is the father of N and L.
M + P: M is the son of P.
From the above relationships, M is the father of L (and N). Therefore, L is the son of M.
L - N: L is the brother of N (L[+]→N).
N ÷ O: N is the daughter of O (N[−] is the daughter of O). Since L is N's brother, L is also the child of O.
O × M: O is the wife of M (O[−] is married to M[+]). This means M is the father of N and L.
M + P: M is the son of P.
From the above relationships, M is the father of L (and N). Therefore, L is the son of M.
