Question

На четырёх автоматических линиях расфасовывали конфеты в упаковки по 300 грамм. На одной линии произошёл сбой, и упаковки стали получаться по 330 грамм. Как с помощью одного взвешивания определить, на какой линии произошёл сбой.

Answer 1

Кладем на весы с первой линии одну пачку, со второй две пачки, с третьей три пачки.
Если на весах 1800 гр. - сбой на четвертой линии,
если 1830 гр. - сбой на первой линии,
если 1860 гр. - сбой на второй линии,
если 1890 гр. сбой на третьей линии.

Answer 2

Determining the Line with the Error

To determine which line experienced the malfunction, we can use a simple weighing method. Since the normal weight of the packages is 300 grams and the packages from the faulty line weigh 330 grams, we can compare the weight of a single package to the expected weight.

Here's how we can proceed:

1. Take a single package from any line and weigh it. 2. If the weight is 300 grams, it means the package is from a normal line. 3. If the weight is 330 grams, it means the package is from the faulty line.

By following this method, we can identify the line that experienced the malfunction.

Please note that this method assumes that the weight of the individual candies within the packages remains consistent across all lines. If there is a variation in the weight of the candies, this method may not provide accurate results.

I hope this helps! Let me know if you have any further questions.
