In a certain code language, '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' and 'A ├╖ B' means 'A is the father of B'. How is H related to L if 'H + J x K ├╖ M - L'?
Wife's mother
Mother's sister
Mother's mother
Father's mother
Mother's mother
Break down the expression into simple relations: H+J (H is mother of J), JxK (J is wife of K), K/M (K is father of M), M-L (M is brother of L). H is thus the mother of K's wife (J), making H the mother-in-law (mother of spouse) of K, and by extension, the grandmother of L.
Break down the expression into simple relations: H+J (H is mother of J), JxK (J is wife of K), K/M (K is father of M), M-L (M is brother of L). H is thus the mother of K's wife (J), making H the mother-in-law (mother of spouse) of K, and by extension, the grandmother of L.
Analyze the expression H + J x K / M - L
Break the string: (H + J) тЖТ H is mother of J; (JxK) тЖТ J is wife of K; (K / M) тЖТ K is father of M; (M - L) тЖТ M is brother of L.
Establish family connections
Since J is the wife of K and K is the father of M, M and L are the children of K and J. H is the mother of J. Since H is the mother of J and J is the mother of L, H is the mother of L's mother.
Identify the relation of H to L
H is the mother of J (L's mother). Therefore, H is the mother's mother of L, which is the maternal grandmother.
A: Wife's mother is not the direct maternal relationship defined here; B: Mother's sister is an aunt, not a grandmother; D: Father's mother is the paternal grandmother, whereas H is linked through the maternal side (J).
C is correct because the expression defines H as the mother of J, who is the mother of L; therefore, H is the maternal grandmother (mother's mother) of L.
In blood relation questions with operators, always identify the gender of the subject first to eliminate impossible options, then map the generation gap.
