You are given 5 bags. There are 10 beads in each of the bags. In four of the bags, the beads each weigh 10 kilograms. In the remaining bag, each bead weighs only 9 kilograms. All the bags and beads look identical. You must find out which bag has the lighter beads. The problem is that all the bags look identical and all the beads look identical. You can use a scale, but it has to be a single-tray scale, not a two-tray balance scale. Also, you may use the scale only once. How can you find out which bag has the lighter beads?
just pulled this off the web...looking at the solution its pretty ing hard... |

Well if you go into this knowing that each bag has 10 and one bag has beads weighing 10 kilograms and the other 9 - then how can you NOT figure it out using a single tray scale?
Confusion. |

put all the bags on the scale and then one by one pull them off and if the weight of the scale goes down by less than 10 kgs then you know the bag you just pulled off was the one. im not sure if that would be using the scale more than once since you are just pulling bags off of it. |

i don't know about this problem...the answer seems kinda stupid...i like your guys' solutions...
| quote: | Label the bags from 1 to 5. Take 1 bead out of Bag 1, and label it 1. Take 2 beads out of Bag 2, and label them both with a 2. Take 3 beads out of Bag 3, and label each with a 3. Continue this pattern with Bags 4 and 5. Put these 15 beads on the tray of the scale.
If all 15 weighed 10 kilograms, the scale would register 150 kilograms. But since one or more of the beads weighs only 9 kilograms, the scale will register less than 150. Subtract the number on the scale from 150. Your answer will tell you the number of the bag with the lighter beads. (If the scale registers 148, it’s bag #2. If the scale registers 145, it’s bag #5.)
