And how can you justify this buying strategy in terms of mathematics?

solar:
550 buying, 800 selling

What is your rationale for this decision?

In game theory, it's called "the picky princess".

The answer can be found on google, but there is no way to apply it to forex.

I have not, intuitively, defined a strategy for myself.

Besides, there is no answer as to what to do if you can't buy all 5 bags.

DmitriyN: The question then is: Can we then sell at or above the average price?

There are no such guarantees.

What I googled looks like it, but it's not quite right.

Leonid, but that's how it is on a purely worldly level. I understand that a sack of potatoes priced at 400-800 roubles is nothing. Well, what if it's not a sack, but something more valuable.
How would you buy then? Below the average? If so, by how much? Above average? At the average? Or should there be some kind of wacky strategy?

If I'm not mistaken, it's Gardner's problem. He wrote a lot of interesting books.
