Using the coded relationships below, determine how I is related to N. Symbols: A - B = A is the mother of B; A * B = A is the husband of B; A % B = A is the brother of B; A $ B = A is the sister of B. Expression: I * J - K % L $ M * N

Question

Accepted Answer

Father-in-law. I is husband of J (I*J). J is mother of K (J-K). K is brother of L (K%L). L is sister of M (L$M). M is husband of N (M*N). So I is the father of K, K is the brother of L, L is the sister of M, and M is the husband of N. I is the father of L (via K and L being siblings). L is the sister of M (M's sister). M married N. Therefore I is the father of M's wife L — making I the father-in-law of M, but M is husband of N. I is father of L; L is sister of M; so I is also parent of M. Hence I is the father of M. M is husband of N, so I is the father-in-law of N.
