Let the original cost price of the bookshelf be Rs. ‘100x’. So the original selling price = 1.15 × 100x = Rs. 115x. Reduced cost price = Rs. (100x – 200). According to question: 1.55 × (100x – 200) = 115x + 300. 155x – 310 = 115x + 300. 40x = 610. x = 15.25. So, the original cost price = Rs 1525 the reduced cost price = Rs. 1325 So, the desired percentage = 200/1325 × 100 = 15.09%.
