Question 9
Taro the beaver goes to the supermarket. He has coins of 1 Beaver, 10 Beaver, 100 Beaver, 1000 Beaver and 10000 Beaver. He wants to buy a computer without changing money. The computer he chooses costs 11010 Beaver.
If all computers that Taro can buy without changing money are ordered from most expensive to cheapest, what position does his computer occupy?
Editorial clarification approved for this practice package: interpret the list as exactly one coin of each of the five denominations, as assumed by the official solution. The original does not explicitly state the quantities.
