Decode the expression from right to left or break it into small segments and map the generational ties. Watch out for gender symbols and reverse relations carefully.
Decode the expression from right to left or break it into small segments and map the generational ties. Watch out for gender symbols and reverse relations carefully.
Step 1: Decode the symbols
A + B means A is the mother of B. A - B means A is the brother of B. A x B means A is the wife of B. A divided by B means A is the father of B.
Step 2: Analyze expression segment by segment
Q + R means Q is the mother of R. R - P means R is the brother of P. P x S means P is the wife of S. S divided by T means S is the father of T. T - J means T is the brother of J. J + K means J is the mother of K.
Step 3: Establish relation between Q and J
Since Q is the mother of R, and R, P, T, J are siblings (R is brother of P, P is wife of S who fathered T, T is brother of J), Q is the mother of all these siblings including J. Therefore, Q is the mother of J's mother (or mother's mother, which is maternal grandmother).
A: Son's daughter is incorrect as Q is female and belongs to a two-generation senior level. B: Father's mother is incorrect because Q is on the maternal side (mother's mother). D: Daughter's son is incorrect as the relation represents grandmother, not a younger generation descendant.
C is correct because Q is the mother of J's mother/parent, making Q the mother's mother (grandmother) of J.
