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

Do you use Codecogs like it was recommended to you many times before?

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.
