To solve this logical reasoning problem, we need to break down the statement given by Deepti and understand the family relationship.
- Deepti introduced Milli to Rajiv with the following statement: "Her brother's father is the only son of my grandfather."
- Analyze the statement:
- "Her brother's father" refers to Milli's father.
- "The only son of my grandfather" indicates Deepti's father, since Deepti's father would be the only son of her grandfather.
- Therefore, Milli's father and Deepti's father is the same person. This means Deepti and Milli share the same father.
- Since both Deepti and Milli have the same father, they are sisters.
Thus, Deepti is related to Milli as her sister.
Therefore, the correct answer is
Sister
.
Let's verify why other options do not fit:
Sister in law
- : This relationship does not fit as Deepti's statement directly identifies the familial link.
Mother
- : Deepti cannot be Milli's mother based on the given information.
Daughter
- : This option does not fit the context since Deepti and Milli are both mentioned as having the same father.
Hence, the conclusion is correct, making the answer Sister.
