Let the initial volumes of alcohol and water be 3x and 2x respectively. Total initial volume = 3x + 2x = 5x. After adding 15 liters of water, the new volume of water = 2x + 15. New ratio: 3x / (2x + 15) = 3/5. Cross-multiplying gives: 15x = 6x + 45 → 9x = 45 x = 5. Total initial volume = 5x = 5 * 5 = 25 liters.
