E Correct answer
Explanation

Let amount in scheme C be x, so scheme B has (45000-x). SI from C at 4% = x × 4/100 × 1 = 0.04x. SI from B at 5% = (45000-x) × 5/100 × 1 = 0.05(45000-x). Equal interest: 0.04x = 0.05(45000-x). So 0.04x = 2250 - 0.05x. Therefore 0.09x = 2250, x = 25000. This matches the claimed answer.
