Let the speaking woman be W. She says the man's mother is 'the only daughter of my mother.' W is herself a daughter of her mother. Therefore the pointed man's mother is W, meaning the woman is his Mother. None of these is wrong because Mother is explicitly available and fully supported. Sister is wrong because the woman is not in the man's generation; she is identified as his parent. Aunt is wrong because an aunt would be a sister of one of his parents, whereas the statement equates the woman herself with his mother. The chain is: W's mother → her only daughter = W → that daughter's son = the pointed man. Reversing the final link shows that the man is W's son. The limiting word 'only' prevents introducing another daughter, so the relationship is unambiguously Mother.

Blood Relation in Logical Reasoning tests the ability to understand family relationships between people. Questions involve identifying the relationship between two members of a family based on given clues. Common relationships include father, mother, brother, sister, uncle, aunt, cousin, nephew, and niece. It is asked in SSC, Bank PO, and Railway exams.

Practice 20-30 questions daily to master this topic for competitive exams.
Types of Blood Relation questions: Direct questions (A is B father, what is B to A?), Coded relations using symbols like + - * /, Sitting arrangement with relations, Series-based family relations, and Gender-based confusion questions. SSC CGL, IBPS PO, and RRB exams commonly ask these types.
Maternal relations are from the mother side: maternal uncle (mama), maternal aunt (mausi), maternal grandfather (nana), maternal grandmother (nani). Paternal relations are from the father side: paternal uncle (chacha/tau), paternal aunt (bua), paternal grandfather (dada), paternal grandmother (dadi). Distinguishing these is key to solving Blood Relation problems.
Common mistakes in Blood Relation questions: Assuming gender when not given, Confusing maternal and paternal relations, Not drawing a proper family tree, Misinterpreting coded symbols, Rushing without reading all clues. Always draw a family tree and verify the final relationship to avoid errors in competitive exams.
