Q: Pointing to a man, Rita says 'His mother is the only daughter of my mother'. How is Rita related to the man? Step-by-step Solution: 1. Break down: 'Only daughter of my mother' = Rita herself 2.
So the man's mother = Rita 3. If Rita is the man's mother, then Rita is his MOTHER Answer: Mother Worked Example 2: Q: A is B's sister. C is B's mother.
D is C's father. E is D's mother. How is A related to D? Step-by-step Solution: 1.
A is B's sister (same generation) 2. C is B's mother (C is parent of both A and B) 3. D is C's father (D is A's grandfather) 4.
Therefore, A is D's granddaughter Answer: Granddaughter Mega Shortcut - The 'Only' Trick: When you see 'only son' or 'only daughter', that person becomes the direct link: • 'Only son of my father' = Myself (if male) or My brother • 'Only daughter of my mother' = Myself (if female) or My sister Another Power Trick - Reverse Method: Start from the answer choices and work backwards. This saves 30-40% time in complex problems. Common Trap #1: Gender Confusion This is the biggest mistake students make. Words like 'child', 'parent', 'sibling' don't specify gender.
Always check if the question asks for a specific gender relationship. For example, if the answer is 'sibling' but options are 'brother/sister', you need additional information to determine gender. Quick Recognition Patterns: • 'Pointing to a photo' questions = Direct relationship type • 'Only son/daughter' statements = Self-reference or direct sibling • Multiple step relationships = Draw the tree, don't solve mentally Time Management: Spend maximum 90 seconds per blood relation question. If it takes longer, mark for review and move ahead.
