There are 5 bags of gold coins, each bag as a large amount of gold coins in them. 1 bag of gold coins are fake. A REAL gold coin weights 100grams, fake gold coin weights 99grams.
Using an ACCURATE scale (note: not a balance), how would you determine which bags are real, and which bag is fake, by taking only 1 reading from that accurate scale? remember you can only take 1 reading.
