You're absolutely right in your logic and calculation. Let's summarize this concisely for clarity: Problem: What is the amount of cement exported from China? Statement I: China's export to America is 65,000 tonnes, which is 8% of total exports. Equation: 0.08 \times \text{Total Exports} = 65,000 \Rightarrow \text{Total Exports} = \frac{65,000}{0.08} = 812,500 \text{ tonnes} Sufficient on its own. Statement II: Total cement export is 15% of 1 million tonnes. Calculation: \text{Total Exports} = 0.15 \times 1,000,000 = 150,000 \text{ tonnes} Sufficient on its own. Conclusion: Each statement individually provides a complete and distinct method to determine the total amount of cement exported from China. Correct answer: Each statement alone is sufficient. This matches option (D) in typical Data Sufficiency formats
