Jars of Marbles

2004 Apr 29, 7:39This was the first question I received and the only non programming related one. You have 10 very large jars of marbles and a digital scale which will accurately display the weight in grams of whatever's placed on top. Some of the jars contain 1 gram marbles and some jars contain 1.1 gram marbles. Using the scale only once, that is you only get 1 measurement, how do you determine which jars contain 1 gram marbles and which contain 1.1 gram marbles?PermalinkComments
