You have fifty bags, each with approximately one hundred balls inside.You have a weighing machine with a digital readout, with 3 places ofdecimals on the display, calibrated in grams, it is capable of weighing aninfinite amount (but it won't have to).
All of the balls in all of the bags weigh 1 gram, except in one bag in whichall 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? You can use theweighing machine only once (which means you can obtain only one reading fromit before it self destructs).
