Correct answer: (D) ₹1,680
Let CP = C, so SP = 1.15C. With 25% less cost (0.75C) and Rs.294 less SP, the profit is 30%: 1.15C - 294 = 1.3 x 0.75C = 0.975C. Solving gives 0.175C = 294, so C = Rs.1,680.

मान लें लागत मूल्य C है, अतः विक्रय मूल्य = 1.15C। 25% कम लागत (0.75C) और ₹294 कम विक्रय मूल्य पर लाभ 30% होता है: 1.15C - 294 = 1.3 x 0.75C = 0.975C। हल करने पर 0.175C = 294, अतः C = ₹1,680।
