    Please help me with math puzzle :-(

    Hi guys I need to solve puzzle. Can anyone help me with this ? Thanks for help.

    1. Prospector Jack Smith has extracted some gold during the California Gold Rush. However, he had a little problem bandits on the way home. Jack thought a lot and after a fifth of whiskey an idea struck him: use that bottle of whiskey to hide gold.
    The idea was good enough and he was able to safely smuggle his catch.
    How many kilograms of gold he extracted (assuming that the bottle was filled to 100%)?
    (
    fractional number with two decimal digits.)

    2. In the home state Jack sold his gold at the price which set by the U.S. government. He has disposed the money as follows:
    - bought the ranch for $8000;
    - donated the church $20;
    - spent $9 for drinks;
    - left himself $200 (and all change) for current expenses;
    The remaining money he put in a bank account at 4% per annum.
    How many dollars he put into the account?

    3.
    It doesn't do to spend this $9 for drinks. On the way home the horse threw off its rider and Jack broke his neck in the fall, so that his family didn't learn where he put the rest of money. Two centuries later the great-great-...-great-grandson of Jack, Martin, received a notice from the bank that his ancestor owned the account.
    How many dollars the bank will pay to Martin?

    4.
    Marty was a very eccentric fellow, and he decided to spend all the money to realize his dream - to see the future. He applied to the company Cryonics Inc. where he was offered a contract for the following conditions:
    - Payment for whole body cryopreservation = $150000;
    - Pay an annual fee = $1000 first year, then increasing anniversarily by % inflation;
    For how long (count in only whole years) he can sign the contract if the inflation is constant and equal to 2% per annum?


    Once again thank you guys for any help.

    Well it seems you will have to check the conversions of gold per liter/gallon to kilograms. Things have different mass whereas liter/gallon is simply volume, or, 'space' if you will. A liter of feathers will weigh a lot less than a liter of gold.

    Then on the 2nd point, it seems to me that you are only told how much he spent, not how much he earned. So it seems to me again that you will have to look up the price of gold during the time of which this story takes place (are you sure you are in a math class?) and then subtract the expenses to come up with the amount that Jack put into his bank account.

    kamgor62, you should solve that puzzle yourself. Currently you jeopardize all new members. If the author will stop to consider anyone who does not passed step 3 until right now - no one will benefit from these answers.

    This is really awkward man, you are such a jerk for posting this here. The puzzle should be for fun, and the less important thing should be winning a chance to join a giveaway... Shame on you man, really. You should be banned on SteamGifts.
