Empty the three-liter container, then transfer the two liters into it. Fill the five-liter container again, and pour into the three-liter container until it is full.

Answer: No valid three-digit number satisfies these conditions. If the ones digit is \(x\), the tens digit is \(x+5\), and the hundreds digit is \(x-3\). The hundreds digit would need to be at least 1, making \(x\) at least 4, but then the tens digit would be at least 9 and the hundreds digit at least 1; the only candidate is 194, whose tens digit is 9 and ones digit is 4, satisfying the first clue, while the hundreds digit 1 is eight less than 9. The answer is 194.
