The answer is NO A "natural" fault in an otherwise fair balance is always proportional to the weight. CASE 1 : The case when there can be an addition error in the measurement is IFF A weight is added to one side intentionally or One of the pan has more weight. THIS can be fairly dealed by the method acquired by the grocer. but since we don't know that this is the case as also pointed out by Dan neely here[^] (only one who came close to the reasoning ) CASE 2 Error due to the beam which is related to the weight. Assume we have 1800 gms of weight in two lots of 900 gms each 1. 900 gms of order is put on the left pan and was found to be 1000 gms on first weighing 2. When we put 900gms on right pan , due to the error the left pan will need 900 x 900 ---------- = 810 gms 1000 So the total weight for which he charges becomes 1000 + 810 = 1810 = 1800 gms (original) + 10 gms (error) This method does reduce the bias of error but still its not accurate QED

hmm. i thought that's what i said here[^] maybe not. close enough for me, though.

I'm wondering how this is possible with a balance. I may need to experiment.

a flexible beam would probably do it

Neither do I. In what way is weighing half at a time different (more accurate?) from weighing the whole thing?

yes :cool: you might be right there, I didnt see that because your reasoning was posted 24 minutes after i posted the solution

You demonstrated it? Did you take video of it? I'd like to see the balance that's faulty that way.

Since nobody was able to solve it yesterday, i wanted to give a chance to those guys who did not tried Puzzle of the (YESTER)Day A grocer discovered his beam balance was faulty, So he started a new method for weighing customer's orders He divides the order into two halves, putting the first half in the left hand of the balance and weights in the right, then do the opposite. The method is unique no doubt, but is the method fair also, to both his customers and himself ? You can hide , you can run, but you cannot escape, Vote it down if you want to escape i mean if you think the puzzle is not worth a repost. HERE is a sample of PAN Balance[^] SOLUTION[^]

hi all , Customer is getting extra order (as much the fault) suppose the beem balance is x% faulty (+ or -) by dividing two parts i. e 50 ( let assume) from first procedure he will give 50 + or - x/2 and from second procedure he will give 50 + or - x/2 . here i am not doing any wrong .. totally getting 'x' (I.E fault ) extra

more clearly saying.. in second procedure u may think 50 - or + x/2 yes u'r correct but due to change in direction to opposite.. 50 - or + ( - x/2) or (+ x/2) hence 50 + or - x/2 will getting
