Rohan bought a bookshelf and sold it at a profit of 15%. Had he bought it for Rs. 200 less and sold it for Rs. 300 more, he would have earned a profit of 55%. The original cost price of the bookshelf is how much percent more than the reduced cost price of the bookshelf?
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%.
