Make McClane Proud…

There are two acceptable answers to this question…did you get either of them?

Answer 2(a):

  1. Fill up the 3-litre jug with water and then tip it all into the 5-litre jug.
  2. Then, again fill up the 3-litre jug and tip it into the 5-litre jug until it becomes full.
  3. This means there will be 1 litre left in the 3-litre jug (3 + 2 = 5).
  4. Empty the 5-litre jug and fill it with the 1 litre that is currently left int he 3-litre jug.
  5. Again, fill up the 3-litre jug and add that to the 1 litre currently in the 5-litre jug.
  6. Be proud of what you’ve achieved.

Answer 2(b):

  1. Fill up the 5-litre jug with water and then tip it all into the 3-litre jug, until it is full.
  2. This means there will be 2 litres left in the 5-litre jug (5 – 3 = 2).
  3. Empty the 3-litre jug and refill it with the 2 litres currently residing in your 5-litre jug.
  4. This means that you will have 1 litre of space left in your 3-litre jug. (3 -2 = 1)
  5. Fill up your 5-litre jug and tip 1 litre of it into your 3-litre jug (filling it up).
  6. You’ll be left with 4 litres in your 5-litre jug.
  7. Be proud of what you’ve achieved.
