A person bought a book at 3/4^{th} of its listed price and sold it at 50\% more than its listed price. What is the percentage of gain in the transaction?

  1. A. 20%
  2. B. 40%
  3. C. 75%
  4. D. 100%

Correct Answer: D. 100%

Explanation

Let listed price = 100. Cost Price (CP) = 75. Selling Price (SP) = 150. Profit = 150 - 75 = 75. Profit percentage = (\frac{75}{75}) \times 100\% = 100\%.
