fill both containers full of water, then tip to make each only have a half of it's water because 1.5+2.5 equals 4


Carl

Here's a simpler way (and doesn't waste as much water): Fill up the 3 litre container till it is full. Pour it into the 5 litre container. Then start filling both containers at the same time until the 5 litre is full. Pour enough from the 5 litre into the 3 litre to make the 3 litre container full (1 litre). You are then left with 4 litres inside the 5 litre container. :D
