'P @ Q' means 'P is the father of Q' 'P & Q' means 'P is the daughter of Q' 'P # Q' means 'P is the brother of Q' If ' A @ B # C # D & E', then how is A related to E?
Explanation:
A @ B → A father of B. B # C → B brother of C. C # D → C brother of D. So A is father of B, C, D. D & E → D daughter of E. Since D is child of A, E must be wife of A. Hence A is husband of E.
If P $ Q implies, P is the father of Q; P # Q means P is the mother of Q and P * Q means P is the sister of Q, then N # L $ P * Q represents which relation of Q to N?
Explanation:
N # L → N mother of L. L $ P → L father of P. So N is grandmother of P. P * Q → P sister of Q, so Q is sibling of P. Q is grandchild of N, but gender of Q is not known. Hence it cannot be determined if Q is grandson or granddaughter.
