Thursday Yuk?

By Oz_Media ·
Well as it is yet another long weekend, I'm outta here!
Time to hit the mainland for a few days camping with friends.

Anyhow, as I will NOT be taking my laptop this time (not on call until Tuesday, YAY!)I will start Friday's Yuk today, or this time a few riddles for the weekend.

RIDDLE:BAGS AD BEADS 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?

RIDDLE:NINE GOLD COINSYou have 9 gold coins. All 9 coins look exactly the same but one coin is a fake and is either lighter or heavier than the other 8 coins. You have a scale - balance type with 2 trays - but can only load it twice. How do you find the fake gold coin?

And some dumb yuks sent from my brother the other night. (he runs a law firm so some of these really aren't funny)

My answer to riddle 1

by grant@rb In reply to Thursday Yuk?

You have 5 bags: #1,#2,#3,#4,#5.
You're going to weigh #1.

Put two beads from #2 in #1.
Put three beads from #3 in #1.
Put four beads from #4 in #1.

Now there are 19 beads in #1.
Weigh #1.

If #1 weighs 190kg, #5 is the light bag.
(19 beads X 10kg) = 190kg

If #1 weighs 186, #4 is the light bag.
(15 beads X 10kg) + (4 beads X 9kg)= 186kg

If #1 weighs 187, #3 is the light bag.
(16 beads X 10kg) + (3 beads X 9kg)= 187kg

If #1 weighs 188, #2 is the light bag.
(17 beads X 10kg) + (2 beads X 9kg)= 188kg

If #1 weighs 180, #1 is the light bag.
(9 beads X 10kg) + (10 beads X 9kg)= 180kg

I've heard riddle 2, so I'll save it for someone else.

Not quite but you get the Brownie points anyhow

by Oz_Media In reply to My answer to riddle 1

Nobody else managed to offer a reasonable answer so you have to take the cake even though your not quite right,
Here's the solution that was provided:
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.)

Good shot anyway!
