    Harry Potter related math problem ;) fun

    An older gentleman, walked into Gringotts and the chatter between goblins, witches and wizards coming and going ceased for a few moments at the sight of the man. Smiling to himself he thought he must look quite strange to them, after all its not often that someone walks in levitating a rather large cauldron weighted down with the knuts saved over the better part of a decade. A rather stern looking goblin watched the man walk towards him. “I’d like to convert all of this into galleons if possible,” the man said politely. Frowning, the Goblin motioned him over to a contraption of sorts and tipped the contents into it. After more than a minute of the sounds of bronze coins falling into the metal contraption, there was a click and a small paper came out of a slot on the right hand side. The goblin took the paper and snorted, “25,569 knuts worth.”

    A) How many galleons did the man leave with?
    B) After the galleon conversion, how many sickles would the man have left with?
    C) From what was left over after both conversions, how many knuts did the man end up keeping?

    In the story, the man thinks the words “better part of a decade.” Let’s assume that he literally did collect all of these knuts in exactly 1 decade (including 2 leap years).

    D) On average, how many knuts did the man add to the cauldron a day?
    E) On average, how many knuts did he collect in the cauldron in 1 single leap year?


    And if anyone's good at word problems:

    Harry woke up to the sounds of business taking place on the streets below. Smiling, he began getting dressed and quickly made his way down the stairs. Tom the barman of the Leaky Cauldron greeted him and Harry smiled and made his way to the brick entrance that would lead him into Diagon Alley. Taking out his wand, Harry tapped a brick near the trashcan. The wall immediately began to open up to the cobblestoned streets of Diagon Alley.

    Harry walked slowly down the street to take in all he could and enjoy his new found freedom. Staying true to his promise to Fudge, he had not ventured outside of Diagon Alley. There was plenty in to keep him occupied here. Harry stopped briefly at the third shop on his left hand side, but saw nothing of interest. He moved along two more doors down. From there he continued by crossing the street to a larger building which held his interest for a few minutes. It was then that he spotted another student that he knew and headed east two doors down on the same side of the street. After a short conversation, Harry headed 4 shops westward and then crossed the street to a small shop. He then heads eastward 2 shops. From there he crosses the street by going northwest, and continues on that side of the street westward 3 buildings and goes directly across the street. Harry meanders on down the street in a westward direction 3 more shops and crosses the street again. Heading in an eastwardly direction again, he continues on that side of the street down 3 more establishments. From there he heads east again 6 buildings. Where did Harry end up?

    1 Galleon = 17 Sickles | 1 Sickle = 29 Knuts | 1 Galleon = 493 Knuts

    This is such a hilarious question!!

    1knut= \frac{1}{493} galleons

    25569 knuts= \frac{25569}{493} galleons.

    You can solve it for sickles in the same way.
