B Correct answer
Explanation

Let CP_A = x, CP_B = y. SP_A = 0.8x (20% loss), SP_B = 1.25y (25% profit). Total SP = 450, and no net gain/loss means total CP = total SP = 450. Also: 0.8x + 1.25y = 450. We need |x - y|. From x + y = 450 and 0.8x + 1.25y = 450. Solving: 0.8x + 1.25(450 - x) = 450 gives x = 200, y = 250. Difference = |200 - 250| = 50.
