Kopeck - "It is usually the smallest denomination within a currency system."
I presume they used kopecks for a purpose and not rubles, dollars or another unit that can be subdivided. That forces the integerness of the amounts and thus the presence of a solution.
- Arnavion 5y agoThe solution to the second question requires half-kopeks.
- karamanolev 5y agoI looked at that problem after posting my original and was utterly confused. Would you trust yourself with an answer involving half-pennies? Seems like an error. As others pointed out, in #1, unless the kopecks are integer, the answer is underconstrained. #2 requires non-integer kopecks.
