I am trying to find this puzzle which I once came across as a kid, but can't seem to recall it properly now (or find it). It goes something like this.
There is a reservoir of capacity 20 litres filled with water. You have 2 buckets of volume x and y (can't seem to recall this information). Without any other forms of measurement, the final aim is to have 2 litres in both buckets. Does anyone remember this puzzle ? It might have been by Lewis Carroll. The values of x,y might have been 3,4 or 4,5 but I am 99% positive about the 20 litres and 2 litres part. Would be very helpful if someone can help me find it.
Edit: Thanks for the replies guys, sorry I don't recollect the original puzzle, but from what I remember there was no wasting of water and the supply of water also wasn't infinite.
