B Correct answer
Explanation

Let CP=100. At 20% gain, SP=120. At 3x price, new SP=360. Gain = 360-100 = 260. Gain percent = (260/100) × 100 = 260%. This tests basic profit/loss concepts.

AI explanation

If the original sale gives a 20% gain, the selling price is 1.2 times the cost price (1.2C). Selling at three times that price means the new selling price is 3 × 1.2C = 3.6C. The gain is now 3.6C - C = 2.6C, which as a percentage of the cost price C is 260%.
