It’s bad enough when you’re out with friends and you have to split the bill.
When you’ve had a few glasses of wine, it’s even worse.
But what happens when your restaurant bill just doesn’t seem to add up – even when you’ve used about three smartphone calculators to work it out?
Well this riddle does just that and has left the internet baffled by where the mystery £1 went.
It’s based on three friends who split a £30 bill at the end of their meal. They each hand the waiter £10 and think they’re on their way.
But the waiter makes a mistake and instead of £30, the group should only have been charged £25.
So, trying to figure out how to split £5 evenly, he hands each diner £1 from the extra £5 and keeps £2 for himself.
Each of the diners get £1 back which means they each paid £9 for their meal, bringing the total to £27.
The waiter then keeps £2, which brings the total to £29… so where’s the extra £1?
Apparently, it’s not actually missing. It’s all down to how you approach the calculation.
If you add it up with the new total cost of the meal, which is £25, plus the £3 given to the diners and the £2 kept by the waiter, it comes to £30. Ta-dah!
This type of brainteaser is called an informal fallacy and means there’s an error in the way you are working out the solution.
