Show answer & explanation
Correct answer: D
Concept: In a Data Sufficiency question, a statement (or combination of statements) is sufficient only if it lets you arrive at one single, definite value for what is asked. If any necessary fact is still missing after using a statement (or combination), that statement (or combination) is not sufficient.
Application:
From Statement I: the company sold 8000 units of product A at Rs. 25 each, so the sale of product A = 8000 × 25 = Rs. 200,000. This fixes product A's sales, but by itself does not confirm whether product A is the company's only source of revenue.
From Statement II: the company has no other product line. This confirms that product A is the ONLY product the company sells, but by itself gives no sales figures at all.
Combining I and II: since product A is the company's only product (from II) and its sale is Rs. 200,000 (from I), the total company sale is exactly Rs. 200,000 — a single, definite value with nothing left unknown.
Cross-check: Checking each statement alone confirms neither is sufficient by itself — Statement I alone leaves open the possibility of other product lines, and Statement II alone gives no quantity or price. Only the combination of both closes every gap, so the correct classification is that I and II together are sufficient, while neither alone is.
