Nítorí kini ní paapọ ni yoo wa ni ọkan rẹ̀? <response>: There will be 3500 gold coins / 5 chest= 700 gold coins in every chest.
So, there will be 500 silver coins / 5 chests = 100 silver coins in each chest.
Then, the number of bronze coins is double the number of silver coins, so there are 2 * 500 = 1000 bronze coins.
So there will be 1000 bronze coins / 5 chests = 200 bronze coins in each chest.
Finally, the total number of coins in every chest will be 700 gold coins + 100 silver coins + 200 bronze coins = 1000 coins.

The final answer: 1000.
