DSSSB TGT CS Mock 03 – Question 009

Pointing to a photograph, Rohit said, ‘Her mother’s only son’s wife is my paternal aunt (chachi/mami/tai).’ How is the lady in the photograph related to Rohit’s father, assuming Rohit’s father has only one brother?

• Sister
• Wife
• Sister-in-law
• Mother

Let’s break down the statement from Rohit’s perspective:
1. ‘My paternal aunt (chachi/tai)’ is the wife of Rohit’s father’s brother.
2. Since Rohit’s father has only one brother, this husband is that only brother.
3. The statement says: ‘Her (lady’s) mother’s only son’s wife is my paternal aunt’.
4. Thus, the lady’s mother’s only son is Rohit’s uncle (Rohit’s father’s brother).
5. If the lady’s mother’s only son is Rohit’s father’s brother, then the lady and Rohit’s father’s brother are siblings (children of the same mother).
6. Therefore, the lady is the sister of Rohit’s father’s brother, which means she is also the sister of Rohit’s father!
Hence, the lady is the sister of Rohit’s father.
