4Q All.
There are five bags of gold that all look identical, and each has ten gold pieces in it.
One of the five bags has fake gold in it.
The real gold, fake gold, and all five bags are identical in every way, except the pieces of fake gold each weigh 1.1 grams, and the real gold pieces each weigh 1 gram.
You have a perfectly accurate digital gram scale and can use it only once.
How do you determine which bag has the fake gold?
