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.
