4300:

Change the last line of the method for 4400 to:

For 4200 we just take a 300 instead of the 200 in the new last line.

This is the end!!!

We divide a 10kg sack into 5000g. Yhen we take one of those 5000 g bags and treat it as it were a 10kg bag i.e. we takw flour from it now.

We do the method for 1100 (900) thus getting in the 5000 g bag a remainder of 3900 (4100) g.

The probability of the costumer being served is 100%. Now that is a good deal!

Two notes:

1) The two methods-for 1100 and for 900-both take 2 measurings.

2)We put back any flour not in the 900 (1100) g bag back into the 5000g bag.

hi Stefy,

That is excellent! I was hoping it would come to that. Well done for your persistence!

Now let's take a break from flour.

I have been typing the non calculator quadratic thing. It's been a struggle of multiple {{{

I hope it is worth it.

Hi bob

Everything falls to the water now. An older friend of mine just noticed that I used the weights as if they were bags of flour!

I will tomorrow try to redo everything!

I had done the same mistake when I first fell onto this puzzle. I don't think we (=you) are completely the wrong way. I think the only constraint is that we cannot use each bag (weight) more than once in the same weighing.

Wow, it's beenmore than a year.

Well, I stumbled upon this thread and remembered we never resolved it to the end. I tried redoing and for now I have everything up to 3300 and I also have 3500 (and of course, the 10000's complement of all of these ).

EDIT: I now everything except 3400, 3600 and their complements.
