In a certain code language,
'M + N' means ‘M is the brother of N’,
'M - N' means ‘M is the husband of N’,
'M x N' means ‘M is the sister of N’ and
'M ÷ N' means ‘M is the mother of N’.
Based on the above, how is A related to F if ‘A - B ÷ C + D x E + F’?
Father's brother
Mother's brother
Brother
Father
Father
Break the expression into individual relations: B is mother of C, C is brother of D, D is sister of E, E is brother of F. A is husband of B, so A is the father of all children (C, D, E, F).
Break the expression into individual relations: B is mother of C, C is brother of D, D is sister of E, E is brother of F. A is husband of B, so A is the father of all children (C, D, E, F).
Break down the expression
Given expression: A - B ÷ C + D x E + F. Relations: 1) A-B (A is husband of B), 2) B÷C (B is mother of C), 3) C+D (C is brother of D), 4) DxE (D is sister of E), 5) E+F (E is brother of F).
Establish the lineage
Since A is the husband of B and B is the mother of C, D, E, and F, it follows that A is the father of all these children, including F.
A: Incorrect as A is the direct parent, not a brother. B: Incorrect as A is the father, not maternal uncle. C: Incorrect as A is of the parental generation, not the same generation as F.
D is correct because based on the relations, A is the husband of B (the mother of F), making A the father of F.
In blood relation coding, always draw the tree from top to bottom (Generations) and denote gender clearly (+ for male, - for female) to avoid errors.
