Arrange all bags in serial and take one coin from first bag ,two coins from second bag three from third bag and take from all ten bags and weigh. from the total weight we can calculate which bag has the coins of weight 27 grms.
Silver is simply the coin's primary metal. "Uncirculated" means that the coin has never been spent in commerce. It can either have come from a mint bag of new coins, from a roll of new coins at a bank, or from a set specially packaged and sold by the Mint.
One bank box contains $100 worth of nickels, which is 2,000 coins.
Yes, you have as many bags as you please, (a minimum of two). You can have as many pieces of gold in the bags as you like and you can determine the weight of the coins as well, but the fake coins will weigh differently (more or less, it's up to you). You have a penny scale, meaning you can place something on a scale put a penny in and then receive a slip with the weight amount on it. If you don't want to see the solution don't continue reading. Answer: For the answer i will use simple denominations of weight. There are three bags with five pieces of gold in each bag. Each real piece weighs one pound and each fake piece weighs 1 pound one ounce. So you have bags A, B, and C and one is full of gold that is slightly heavier (fake). You take one coin from the first bag, two coins from the second, and three from the third and you put all 6 coins on the scale and weigh them. Now if all coins were real this should amount to 6 pounds, however, that isn't the case and you can determine the the fake bag by the overage weight. So for instance if the reading comes back with 6 pounds 2 ounces then bag B is the one with the fakes. Since every fake piece is one extra ounce and you're two ounces over it must be the bag that you took 2 coins from which would be bag B.. If it was 6 pounds 3 ounces then it would be bag C and 6 lbs one oz would be bag A. Alternatively, since you decide the amount of coins in each bag you could specifically say that you want one coin in the first bag two coins in the second, three in the third etc. and just weigh the bags together. Then you just follow the same train of thought to determine the fake bag.
16 % of the coins are dimes. 4 of a total of 25.
