Jack and Jill went up the hill…….

image6.jpgWhen Jack and Jill went up the hill to fetch pails of water they only had two jugs, one that holds exactly 3 litres, and one that holds exactly 5 litres. Using just these two jugs, how did they measure out exactly 4 litres of water?

    1. That’s a really interesting idea Max but I think you need to delve a little further. You see, the jugs they have are wide at the top and narrow at the bottom so extremely difficult to judge where halfway is. I’m sure there has to be a better way?

    1. That was my first idea too…but then I thought about it some more. Where are you going to put your 2litres of water that’s in your 5litre bucket while you “repeat”?

      1. Good thought (Mrs Bowler Hat). I was about to tell someone off for going to bed too late…and then I saw it was you…blogging away into the night! I might have to find another brain teaser just for you! Mrs M

  1. I tried different ways of filling and emptying the jugs. I tried to make one litre so then you could easily add the 3 litres. Mum did it a different way. I wonder how many ways we can find 🙂

  2. Fill (3) till full.
    Pour all 3 liters from (3) into (5).

    Fill (3) again till full.
    Pour (3) into (5) till (5) is full.
    (3) will now have 1 liter.

    Empty (5).
    Pour 1 liter from (3) into (5).

    Fill (3) again till full.
    Pour all 3 liters from (3) into (5).
    You now have 4 liters in (5)-liter bucket.

  3. fill the 5L jug then put it into the 3L and you will have 2L left.empty the 3L and put the 2L left into it.now fill the 5L and pour some into the 3L you should have 4L left.
