B Correct answer
Explanation

Let CP = x. Profit = 320% of CP = 3.2x, so SP = CP + Profit = x + 3.2x = 4.2x. New CP = 1.25x (25% increase). SP remains 4.2x. New profit = 4.2x - 1.25x = 2.95x. Profit as % of SP = (2.95x / 4.2x) × 100 = 70.2%. This is approximately 70%, matching option B. Options A (30%) and D (250%) are incorrect.
