This is very good viedo 👌👌
Thanks so much 😊
Peter stole $100. An hour later John bought a $70 goods from the same shop. How much did the shop lose? $100. I couldn't care less if Peter and John knows each other, are accomplices, or even the same person.
Bvyukmhui😢😢😂😂😮😅😅😅😢🎉❤❤❤❤
This is ONLY correct if the groceries were given to the store FOR FREE. The total loss is $200.
$100 was stolen. The store lost $100. That's it. That he made a purchase with the $100 is irrelevant. You can also look at it another way. The thief left the store with $100 more ($70 in goods / $30 cash) than he came in with. If the store's loss is $200 and the thief's gain is $100, who did the store lose the other $100 to?
It's not a great breakdown, but it is correct . Basically, the thief decided to steal the goods instead of the $70. In the end, the thief has $30+the goods. While the store has $70.
Can someone explain to me how the heck is 5x5x5 125 because I got 5x3=15 then 15x5=75 HOW THE HECK IS IT 125?!HOW DO THEY GET IT?
Explain in fortnite terms?

Good morning
Good. Night
So i read that this is riddle should be taken as a riddle only, and not a mathematics problem. That's why the answer is $100. Not like in real life where they loose more. I just want to know what individual came up with this...probably a bad cashier. Lol
How exactly in real life would they lose more than $100?
@@Namath1000 Don't worry about it. You're the type to sell your TV for $100, change your mind, get back your $100 but not the TV and be happy.
@@saints9988 If I were to sell my TV for $100 I would have the $100 -- I wouldn't have to "get it back" later. Please try to focus. As to not worrying about it, I am worrying about it. Your stupidity is painful.
This is so very hardworking 😢😢
Thank you 🎉🎉🎉😢❤❤❤❤
it's ok
Awesome 🎉
how did you get 74 ?
This would be accurate if the wholesale costs of the goods were 70 dollars which wouldn't be the case
Very helpful sir

I disagree. Ownership of money and goods always remains with the last legitimate owner. The store keep owns $100. It is stolen by the thief. There is no legitimate exchange. Therefore, ownership remains with the Shopkeeper who is down $100. The thief returns and uses the $100 he does not legitimately own to purchase 70 of goods. When the thief gives the shopkeeper the stolen $100 as payment, he gets another $70 of goods where ownership does not transfer because the payment is fraudulent... and he receives another $30 as change in another fraudulent transfer from shopkeeper to the thief. The balance is the Storekeeper has lost $200 because none of the transfers of ownership were legitimate. Whereas, the thief has seen $200 of goods and money pass that they have had no legal ownership of pass through their hands.
I'm going to reverse the order to show you the problem here. The problem with your conclusion is that it ignores balancing the equation. Who possesses the initial stolen $100? The thief or the store? Since the thief gave the stolen $100 to the store in exchange for the goods and change, the store's till has the $100 inside of it. As such, the store only lost $100 not $200. The problem with your premise is that you ignore a critical point. Money is fungible. Let's try looking at the problem from a different angle. Let's assume you have a coworker. His name is John. John breaks into a locker at work, and steals a 100 bill from the boss's wallet. John goes to the store later and exchanges $100 and buys $70 in goods and gets $30 back in change. Did the store lose out, or did the boss? I think the answer is pretty clear here. For the store, the transaction was legitimate. And here's the thing. The cash register will record that transaction as legitimate no matter where that $100 came from.
@@godaistudios The moment the thief removes the $100... the till is minus 100.
Would you answer be the same if the thief used another $100 note which he legitimately owned to purchase?
@@StephenWong14 The thief did not us his own money... that is the point.
@@andrewsmith8729 So is your answer "no" to my question?
Nice 👍🏽
I love you so much😊
it so good
Wow this helped me a lot😊
Thanks, it's helped me a lot
Thank you so much😍 It's help me a lot❤️
The easiest way to explain it is what if the thief stole the $100 after buying the goods? the shop loses $100. whether he stole the $100 before the transaction or after the transaction makes no difference the shop still loses $100😢 Although they did make a profit on the transaction
Exactly. Baffles me some idiots don't understand simple maths.
I guess there's a brain teaser or a riddle I'd have to accept this if I were the stoner A store owner I would be out $200. The potential to gain a profit the retail sale of the products that were worth $70 retail plus the $30 that he got in charge that's $100 plus the register the till would be off by $100. To the store that's a $200 loss.
That doesn't really make sense, though. It's not possible for the store to lose more money than if the thief didn't buy anything. The original $100 makes it back in some way, and if you want to make the claim about the register being down $100, then you can't take the $70 away on top of it because it implies the store didn't know.
Me know a Ready
You are not showing the $100 stolen which will still show up missing when the register shows a shortage when closing.
Register has $100. Take away $100 = $0. Purchase Goods for $70. Register now has $70. $30 missing from Register, and $70 in Goods stolen.
I did this type of math equation and i went crazy like literally when i was putting the numbers in smallest to largest its so easy to skip one
thank you ive never understood mean but i do now thank you :)
Just before the exam perfect😂😂😂

I wishhhhhhhhhhh the voice was a human voice because it would help me concentrate While I watch this video just giving some advise for your channel .
Who is watching this on 2024
Idk why l still don’t understand. Thanks for the vid❤
thanks
11?
I dont get how you do the 2nd question
It’s not even in order..
It’s not even in order..
Nice video but the last one makes no sense. The example you gave each of them can be a superset of each other. A superset is a set that contains all elements of the other with at least one more element.
You're right, it made absolutely no sense! I'm not sure how I managed that 🙄 I've edited that part out of this one and an updated version will be posted on Tuesday! Thanks for letting me know 🙂
Tomorrow is my exams
Thanks
Thx
