Original cost price = 100

Original selling price = 100 + 320% of 100 = 420

New cost price = 100 + 25% of 100 = 125

Since the selling price remains constant, the profit is:

Profit = Selling price - New cost price = 420 - 125 = 295

Percentage of selling price that is profit:

(295 / 420) * 100% ≈ 70%

So, the correct answer is 70%.
