Break down the blood relation expression from right to left or build the tree step-by-step; observe gender and generations.
Break down the blood relation expression from right to left or build the tree step-by-step; observe gender and generations.
Analyze the expression D ÷ E
D ÷ E means D is the wife of E. Since D is female and wife, E must be male.
Analyze C x D
C x D means C is the daughter of D. So, C is the daughter of E and D.
Analyze B - C
B - C means B is the husband of C. This makes B the son-in-law of D and E.
Analyze A + B
A + B means A is the son of B. Since A is the son of B, and B is the husband of C, A is the son of C and the grandson of D and E.
A: A is the son, not daughter's son; B: A is the son, not brother; D: A is the son, not son's son.
C is correct because the sequence A+B-CxD÷E establishes that A is the child of C, who is the daughter of D and E; thus, A is the grandson of E.
In blood relations, always determine gender using symbols (e.g., + for male, - for female) to avoid confusion during multi-generational analysis.
