You have fifty bags, each with approximately one hundred balls inside.You have a weighing machine with a digital readout, with 3 places of decimals on the display, calibrated in grams, it is capable of weighing an infinite amount (but it won't have to).
All of the balls in all of the bags weigh 1.000 gram, except in one bag in which all of the balls weigh 1.001 grams.
You cannot tell by look or feel which bag has the heavier balls.
How do you determine which bag contains the heavier balls?
Note: The weighing machine may only be used once.
