D Correct answer
Explanation

Interest from A = 1120 * 4 * 0.05 = 224. Let P be the amount in B. Interest from B = P * 10 * 0.04 = 0.4P. Since interests are equal, 0.4P = 224 => P = 560. Total money = 1120 + 560 = 1680.

AI explanation

The interest from bank A is calculated as (1120 * 5 * 4) / 100 = Rs. 224. Let the remaining amount deposited in bank B be x, so its interest is (x * 4 * 10) / 100 = 224. Solving 0.4x = 224 gives x = Rs. 560. The total money she had is the sum of both deposits, which is 1120 + 560 = Rs. 1680.
