The 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.
