math is here are u ready?
a rich guy gave a 10 jewelery makers 100 gram of gold each, each jewelery maker has to make 10 gold rings and they must be equal, means 100=10rings each ring = 10 grams, now one of the guys stole 1 gram from each ring so he stole 10 grams from the 100, so he made the ring weights 9 grams not 10 as it should, all other jewellery's did not steel any grams, now one smart guy said I can make smart weight and put some of the rings on the scale in one time I for sure will tel u who stole the 10 grams, did u know how he did it?
assuming that the rich guy knows he is short 1 gram on each of ten rings...
assign a number to each jeweller.
put 1 ring from no. 1 jeweller on the scale
put 2 rings from #2
put 3 rings from #3
etc for all ten - total weight should be 55 * 10 = 550grams
if the final weight is 1 gram short, then it was jeweller #1
if 2 grams short, then its was #2, etc, etc
Factors Guiding The Purchase Of Legal For Trade Scales
Legal for trade scales are used in places where the manufacturers require commercial applications to sell the product by weight. The term legal for trade (LFT) originates from the legally approved status of the balance unusually with certification granted by National Type Evaluation Program (NTEP). There are various kinds of legal for trade scales which can be used for a number of purposes like weighing fruit for selling, weighing meat before cutting, determining shipping cost after weighing as in courier services, weighing gold and silver in jewelry and antique stores etc.
Certain factors should take priority in purchase decisions of legal for trade scales.
- Platform size: Keeping in view the unique shape of edible and other items you will place on the scale e.g. small fruits or big meat pieces you should buy the LFT accordingly.
- Platform capacity: you must determine the minimum amount of weight and the maximum volume that you would place on it, for example, equipments and fruits will weigh more and occupy more space than coins and jewelry items.
- Accuracy: reading accuracy is ofcourse the basic and most desirable feature of all scales. But each scale is available for pre-determined minimum and maximum limits. This is called scale sensitivity. Unique, fragile jewelry items, stones etc, need to be weighed with more precision going into milligrams than items in courier services or large shipments which go into several kilograms.
- Durability: make sure you buy scales made of high quality material according to the climatic and measuring conditions you expose it to.
It has been noticed that even with the availability of digital scales buyers are clueless about the suitability of features to their manufactured goods. An additional feature may come at an increased price, so there's no need to go for something that falls out of your measuring requirements. These features include:
- TARE: this unique feature allows you to deduct the weight of any pan or container you place on the platform so that you get only desired measurement of the object (in the pan).
- Battery or AC operated: to ensure portability and non-stop usage for applications other than the farm stand.
- Dual display: this feature eases the mind of the customer who can read the similar information like the retail clerk at the counter.
- Warranty: mishandling of equipment on your part can make warranty void so buy one that gives a good warranty period and then use it with care.
- Spill protection: depending on the state of the substance to be weighed: liquid, powder, wet/moist, volatile you would want to order a unit whose display and user buttons are sealed to prevent spillage or chemical reaction between the item and scale body.
10. Weighing Units: according to your standard item weight range you can opt for either pounds/ounces or kilograms/grams. Most digital scales provide both.
11. Government requirements: Legal for trade scales are approved by NTEP. However, certain regions within and outside the US may require you to go for other certifications.
