The cashier's problem

The cashier's problem

The bank teller could tell us some interesting experiences that occur in the daily routine and some curious problems that arise in the form of puzzles.

What would you do, for example, when an elderly gentleman who, like most mortals is reluctant to calculations, gives us a $ 200 bill and tells us: "Give me some 1 dollar bills, ten times more 2 bills and the rest in 5 dollar bills".


The cashier handed out 5 bills of 1 dollar, 50 of 2 dollars and 19 of 5 dollars.
