You only need to open one box and any will do: for example, open the lunch box labelled ‘Mel’. If the sandwich is peanut butter you will know that it belongs to Louis. Because all the boxes are wrongly labelled, you will know that the box labelled ‘Alice’ must contain Mel’s jam and peanut butter sandwiches, and vice versa.

1 litre to 7 litres with the two jugs. (See Teachers Notes tn48.htm)
