Concept:
This is a
ratio distribution problem:
- Combine ratios step-by-step
- Maintain consistency across relations
Step 1: Assign ratios.
\[
\text{Son : Wife} = 3 : 1
\]
\[
\text{Wife : Daughter} = 3 : 1
\]
Step 2: Make ratios consistent.
Let wife = 3 units (common)
\[
\text{Son : Wife} = 9 : 3
\]
\[
\text{Wife : Daughter} = 3 : 1
\]
Thus:
\[
\text{Son : Wife : Daughter} = 9 : 3 : 1
\]
Step 3: Use given condition.
\[
\text{Difference (Son - Daughter)} = 9 - 1 = 8 \text{ units}
\]
\[
8 \text{ units} = 10{,}000
\Rightarrow 1 \text{ unit} = 1250
\]
Step 4: Find total property.
\[
\text{Total units} = 9 + 3 + 1 = 13
\]
\[
\text{Total} = 13 \times 1250 = 16{,}250
\]
Step 5: Option analysis.
- (A) 20,000: Incorrect $\times$
- (B) 16,000: Incorrect $\times$
- (C) 15,750: Incorrect $\times$
- (D) 16,250: Correct \checkmark
- (E) 20,500: Incorrect $\times$
Conclusion:
Thus, the correct answer is
Option (D).
