C Correct answer
Explanation

Let Marked Price = 100. Purchase Price = 100 - 20% = 80. Selling Price = 100. Profit = 100 - 80 = 20. Profit % = (20/80) * 100 = 25%.

AI explanation

Let the marked price be 100. Shirish bought the watch at a 20% discount, so his cost price is 80. He sold it at the marked price, meaning his selling price is 100. The gain percentage formula is ((Selling Price - Cost Price) / Cost Price) * 100, which gives ((100 - 80) / 80) * 100 = 25%. The gain percent is 25%.
