Hi again

@Bruno
The second time you got it wrong, it's 75 numbers!!! There is no mentioning that the random numbers may not contain duplicates!!!

Any comment on a perfectly working solution the like "wouldn't work", even by replacing it with a statement like "mission impossible" makes me really cross.
If you don't bother to read the question properly, neither to try out provided solutions, please just keep your wisdoms to yourself.

Offering on this theme a solution involving the simplex algorithm is completely offtopic, you read obviously somewhere something, but can't get loose ends fit.

@Paul
Great solution, efficiently and fast, and quite comfortable when using vba for recalculations!

Cheers
