perplexus.info :: Weights and Scales : 6 coins

6 coins (Posted on 2016-01-13)

There are 6 coins weighing 1, 2, 3, 4, 5 and 6 grams that look the same, except for their labels. The labels are supposed to display the weights of the coins.

How can you determine whether all the labels are correct,
using the balance scale only twice?
