You should pick a coin from chest B. This coin you pick (either gold or silver) will be the entire content of the chest. If it is gold, chest B is 100 gold coins, if it is silver, chest C will contain the 100 gold coins.

Let say you pick gold. As chest B cannot contain silver and gold, it must contain only gold.
Let say you pick silver. As chest B cannot contain silver and gold, it must contain only silver. Chest A cannot contain only gold and as chest B contains only silver, chest A must contain silver and gold. That leaves chest C for only gold.
