Store S sold a total of 90 copies of a certain book during the seven days of last week, and it sold different numbers of copies on any two of the days.
"different numbers of copies on any *two* of the days." What does this mean?
Is it trying to say that if I were to randomly select two days of the week, the number of copies will be different on each? Does it mean the number of copies on each day is different?
A math wording problem. Need some help with the English.?

It means the number of copies sold on each day is different. It is poorly worded but that is what it must mean.

It means no two days have the same number of copies sold. In short, each day of the week has different number of copies sold compared to other days.

I think it's saying the number of copies for each day is different. But of course, this guarantees that if you were to randomly select two days, the number of copies couldn't possibly be the same for those two days since it has to be different for every day.
