NIMCET 2026 — Reasoning PYQ

To solve this problem, let us break down the relationships step-by-step using logical deduction. Let the speaker be denoted as $S$.

Step 1: Analyze the statement "Mira’s mother-in-law’s mother is my grandmother."

• Let $H$ be Mira's husband.

• "Mira's mother-in-law" is the mother of $H$. Let us call her $M_{il}$.

• The phrase "Mira’s mother-in-law’s mother" refers to $M_{il}$'s mother.

• The problem states: $M_{il}\text{’s mother}=S\text{’s grandmother}$.

Step 2: Establish the relationship between the Speaker ($S$) and Mira’s husband ($H$).

• Since $M_{il}\text{’s mother}$ is $S\text{’s grandmother}$, this implies that $M_{il}$ and $S\text{’s parent}$ are children of the same grandmother.

• Therefore, $M_{il}$ is the aunt of $S$ (as $M_{il}$ is not $S$'s mother, because $S$'s mother's offsprings are unmarried).

• If $M_{il}$ is $S$'s aunt, then her son ($H$) is $S$'s cousin.

Step 3: Evaluate the constraints.

• The statement "All my mother’s offsprings are unmarried till date" confirms that $S$ is not married to Mira, eliminating option 4.

• Since $H$ is the son of $S$'s aunt, we can conclude that Mira is the wife of $S$'s aunt's son.

Conclusion:

Comparing our deduction to the given options, the correct answer is Option 3: Mira is the wife of my aunt’s son.
