Explanation:
A, B, and C are brothers. E is the father of A, so E is also the father of C. C is the husband of D, which means D is the wife of C. Therefore, D is the daughter-in-law of E.
'A # B' means 'A is the husband of B' 'A @ B' means 'A is the son of B' 'A & B' means 'A is the mother of B' 'A % B' means 'A is grandfather of B' If 'K % N @ P # R', then how is K related to R?
Explanation:
K % N → K is grandfather of N. N @ P → N is son of P, so P is parent of N (father). P # R → P is husband of R, so R is wife of P. K is grandfather of N, and N is son of P, so K is father of P. Since P is husband of R, K is father-in-law of R.
