Question
In a certain code language:Â - 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 father of B'.        Question: How is M related to L if 'P + M ¸ K # L & E'?ÂSolution
- P + M
→ P is the brother of M - M ¸ K
→ M is the father of K - K # L
→ K is the wife of L
→ So, L is the husband of K - L & E
→ L is the son of E
- P is M’s brother
- M is K’s father
- K is L’s wife
- So, L is M’s son-in-law (because M is the father of K, and K is married to L)
- That means M is L’s father-in-law
- And M is his wife’s father
