    Yesterday I presented you guys with the most epic, beautiful women of the world thread:
    [FAP Free Zone] Beautiful Brazilian Women [Need I Say More?]


    Today, I present to you guys this marketing riddle


    It's a riddle a buddy of mine from a business class asked me a couple of years ago.


    You're walking in the mall and you happen to walk by a shoe store.

    Through the window, you see this pair of shoes that you really like.
    You walk inside the store and ask the sales associate how much they are.
    The sales associate responds, $97.00

    You don't have the money, so you go back home.
    Once you get home, you ask your parents for money.
    Your mother gives you $50. Your father gives you $50.

    With a total of $100, you head back to the store and buy the pair shoes.
    You purchase the $97 pair of shoes and get $3 back.

    Once you get back home with the pair of shoes, you give your mother and father each $1 back. They let you keep the last dollar.

    Since you gave them each $1 back, you still owe them $49 each.


    Let's add everything back up to make sure it all checks out.

    $49 + $49 = $98
    + $1 you kept =$99


    Where's the missing dollar!?


    Notes:
    • Since this is a marketing forum, Tax is not the answer.
    • Since this is a blackhat marketing forum, neither is google (meaning that the answers in google are incorrect).
    • If you know this riddle and the answer, please refrain from answering in the beginning on the thread so other members have a go at it.

    you pay 49 back to each

    and you already payed 2 dollars

    so that adds up

    98 + 2

    not 98 + 1


    But very tricky riddle :) ...; fun to solve !!!

    As neutralhatter said, you are adding instead of subtracting.

    You don't owe them $100 because they already got $2. So you owe them $98 but if you really got to keep the dollar then you owe them $97 hence subtracting. So $100 got broken into:shoes $97, parents $2, kid $1.

    You didn't pay them back. You only gave them 1 dollar back from the original $50 you borrowed from them. You still owe them each $49.

    49+49=98

    You still owe 98.

    You only got to keep 1 dollar.

    98+1=99

    Its $48.50 + $48.50 = $97 to be repaid

    First Payment
    $50 - $1 for mother
    $50 - $1 for father
    Plus loan forgiveness of $.5 from each one
    $49 - $.50 for mother
    $49 - $.50 for father.


    There is no missing dollar as all $3 is accounted for.

    That's not it dude :D (-1) x (-1) would always be (-1) square i.e 1 hehe. I have done a mistake, but only those who know the theory of math can tell lol :D It is not so easy haha :D

    Yes but the trick is that they let you keep one dollar so you only owe them 99$. and since you gave them each 1$, you're left with 97$ that you need to pay back.
    that 48.5$ for each of them instead of 49$ you used.
    Of course assuming that they equally gave you 0.5$. If only one of them gave you 1$ then you have to pay 48$ to him and 49$ to the other.

    49 + 49 = 98
    you already payed 2

    97 + the 1 dollar in your pocket = 98

    so the calculation is correct... you owe 98 dollars

    Sn0rt is putting us on the wrong way. ;-)

    What you did is right, assuming that the square root of -1 is correct, which is not. :D

    This problem has no solution by conventional mathematics. unless you have a punch in between.


    Amount Required = $97
    Amount in debt = $100
    Amount repaid = $1 + $1 = $2
    Pending amount = $49 + $49 = $98
    Remaining dollar = with boy.


    Curious to know what the answer is....

    Well if the shoes cost 97, your left with 3 dollars. Give one to your mom, one to your dad, and you keep one. Then everything is accounted for.
