B. Statement (2) alone is sufficient, but statement (1) alone is not sufficient to answer the question.
C. Both statements taken together are sufficient to answer the questions, but neither statement alone is sufficient.
D. Each statement alone is sufficient.
Explanation: ধরি, purchase cost=\(x\). So, listed price = \(x + x\) এর \(20\% = 1.2x\). For statement 1 alone, new listed price = \(1.2x-10\%\) of \(1.2x=1.08x\). So, net profit = \(1.08x-x=0.08x\). According to question, \(0.08x=10,000\). So, \(x=125,000\). For statement 2 alone, \(1.2x=50,000\). So, \(x=41,666.67\). Correct Answer (D)
