ok here is the question:
3 guys walk into a store, let's say a cell phone store, and they like a phone, the salesman says it's $30. so every one of the 3 guys paid $10.
they walk out , but as soon as they walk out the manager said to the salesman that's too much, you have over charged the guys, and he gives him $5 to give back to the guys. the salesman walks out to the 3 guys cars and returns to each one $1 (one dollar) and pockets $2 (two dollars).
so that makes it like that:each guy originally paid $10 - $1 = $9 each guy paid, right? total of 3 x 9 = $27 and the salesman pocketed $2 so the total is $27 + $2 = $29
where is the missing dollar??? i challenge anyone for this, and no BS if you gonna challenge to solve it, i bid you $1000 (one thousand dollars).
