Wait… where did that 1 BTC go?! 😱🧐
Three friends go out to eat and get a bill for 30 BTC, so they each chip in 10 BTC — that's 3 × 10 = 30 BTC.
Later, the waiter realizes the actual bill was only 25 BTC. Oops! So he takes 5 BTC to return to them. But here's the problem: 5 BTC can’t be split evenly among three people.
So the waiter decides to give 1 BTC back to each person (totaling 3 BTC) and keep the remaining 2 BTC as a “tip.”
Now, each person paid 10 BTC originally but got 1 BTC back, so they actually paid 9 BTC each.
That’s 3 × 9 = 27 BTC.
And the waiter kept 2 BTC.
So… 27 BTC + 2 BTC = 29 BTC?!
But they paid 30 BTC!
Where’s the missing 1 BTC?? 🤯
Did you spot the trick? 😏
