My answer to #1 is less than 8 kopecks, and Masha has less than one. There's a problem: nowadays kopecks are the minimal unit of currency. Either it means you have to think of the old Imperial money units (polushka, 1/4 of kopeck), or think of fractional amounts of money.

I assumed kopecks were pennies. If Misha needs one, and Masha doesn't have enough to give her one, than Masha must have none. So the answer follows from that.

But naturally, at first you assume the numbers are natural. :)

Well, yes, otherwise you'd have an infinite number of solutions.

How can they combine their money if one of them doesn't have any?

Communism?

Ok. I literally laughed out loud.

Seems like Mishalacked isn't great at making deals.
