Can anyone answer this riddle for me as it holds the password to something i need to unlock: You are given 5 bags. There are 10 beads in each of the bags. In four of the bags, the beads each weigh 10 grams. In the remaining bag, each bead weighs only 9 grams. All the bags and beads look and feel identical. You must find out which bag has the lighter beads. 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. After you place something on the scale it will get stuck so taking anything off or putting anything on will not be weighed. You cant tell the difference by picking them up, they will all feal the same. How can you find out which bag has the lighter beads?

Take 4 beads from bag 1, 3 beads from bag 2, 2 beads from bag 3, and 1 bead from bag 4. Weigh these 10 beads.

If they weigh 100 grams then bag 5 must have the 9 gram beads. 4(10)+3(10)+2(10)+1(10)+0(9)=100
If they way 99 grams then bag 4 must have the 9 gram beads. 4(10)+3(10)+2(10)+1(9)+0(9)=99
If they way 98 grams then bag 3 must have the 9 gram beads. 4(10)+3(10)+2(9)+1(10)+0(9)=98
If they way 97 grams then bag 3 must have the 9 gram beads. 4(10)+3(9)+2(10)+1(10)+0(9)=97
If they way 96 grams then bag 3 must have the 9 gram beads. 4(9)+3(10)+2(10)+1(10)+0(9)=96

I love riddles!

What you do: Label the bags from one to five. 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.)

I'd probably choose 3/5 of the bags and put them on the scale... if it weighs 300g, its a 1/2 chance... if it weighs 290g, its a 1/3 chance... which is better than a 1/5 chance

enee menee minee mo!

edit: Mappie's idea seems logical
