Symbols are defined: 'P $ Q' = P is the brother of Q; 'P # Q' = P is the sister of Q; 'P ^ Q' = P is the brother of Q's father; 'P @ Q' = P is the wife of Q; 'P % Q' = P is the mother of Q; 'P * Q' = P is the father of Q. Using these, determine how J is related to Z in: J % K # L @ M * N $ Z.

1. Father's mother
2. Mother
3. Mother's mother
4. Mother's sister

Correct answer: Mother's mother

Solution

J % K: J is mother of K. K # L: K is sister of L, so L is also J's child (daughter). L @ M: L is wife of M. M * N: M is father of N. N $ Z: N is brother of Z. So M is also father of Z. Since L (J's daughter) is wife of M, J is Z's maternal grandmother, i.e., Mother's mother.
