There are 3 cans containing different foods.
Nuts in one can.
Sliced Peaches in juices in another and the third can contains sliced oranges in juices.
Someone has steamed off and switched the labels of all the cans so every can will have a label that is not the actual food inside it.
Can you figure out which cans contain which foods without opening any?
Since it was stated "every can will have a label that is not the actual food inside it", we know the two cans containing liquid have been switched. However, I wouldnt assume just by switching the labels it would be that easy, so I would say it goes by the sound of the denisity. Even though both cans could possibly be the same net weight, orange juice is not as dense as peach juice. So, the only way to find out would be to shake both the cans and listen to the way the contents move inside. Just like the nuts, the sound of the peaches and the sound of the oranges shaking in their juices will be completely different due to one being more dense than the other.
