Hello, curious minds and puzzle enthusiasts! Ready for another brain teaser that’ll have you scratching your head? Let’s get on with it then!

The Puzzle

Imagine this: Three friends decide to go out for a fancy dinner on some special occasion. The total bill comes to $30. Each friend chips in $10, giving the waiter a total of $30.

But wait! The restaurant manager realizes there’s been a mistake — the actual cost of the meal is only $25. To correct this, he gives $5 to the waiter and asks him to return it to the friends.

Now, the friends, feeling generous, decide to let the waiter keep $2 as a tip for his excellent service. The waiter then gives $1 back to each friend. So, if you’re keeping track, each friend gets $1 back, meaning they each paid $9 for the dinner (totaling $27). Meanwhile, the waiter has a $2 tip.

But hang on a second — $27 (paid) + $2 (waiter’s tip) = $29. Where’s the missing dollar? Take a moment, dear readers, to chew on this puzzler. Do a little mental math, maybe even discuss it with a friend over a cup of coffee. Ready for the reveal? Here we go!

Solution

Drumroll🥁, please… There is no missing dollar!

This is a classic example of how our minds can
