In general if you have n weights at your disposal you can solve the puzzle up to 3 n marbles included.
12 marbles riddle.
That is a small dish hangs from each end of a rod that is balanced in the middle.
One of them is fake could be heavier or lighter than the rest of the 11 all the others weight exactly the same.
You don t know if that one is heavier or lighter.
An amazing flash version of this problem is presented here.
You have a balance scale.
Once the group is determined split the marbles into 2 groups with 2 marbles each.
If the 2 groups weigh the same the heavier marble is in the 3rd group.
For convenience sake let s name the balls 1 12.
If the measurement is even 1 2 3 4 5 6 7 8 are normal.
Here is an interesting riddle involving 12 marbles and a balance scale.
The scales are of the old balance variety.
Split the marbles into 3 groups with 4 marbles each.
You are given a set of scales and 12 marbles.
You have twelve marbles.
The scales are of the old balance variety.
So another perfectly valid solution to the 12 marbles puzzle might even be.
If the first measurement is uneven then 9 10 11 12 are normal marbles.
Find the fake ball.
One of the 12 marbles is irregular but you don t know whether it s heavier or lighte.
2v2 8 xy 1v1 0 z 3v3 2 xy 1v1 1 z 1v1 0 which requires only two weights in one third of the cases.
You have 12 marbles.
Use the scale to determine the group that.
You are give 12 identical looking balls.
Pick 2 groups and use the scale to determine which group contains the heavier marble.
You can perform up to a maximum of three weighings to find out which marble has the different weight and if it is heavier or lighter than the others.
Number the balls measure 1234 against 5678.
The device enables you to conclude either that the contents of the dishes weigh the same or that the dish that falls lower has heavier contents than the other.
Here is a riddle for you you are given 12 marbles and 1 of them is either heavier or lighter than the others you are given 12 marbles and 1 of them is either heavier or lighter than the other 11.
You have a balancing scale you can use to find this marble and figure out if it weighs more or less than the others.
You a provided with a simple mechanical balance and you are restricted to only 3 uses.
They all weigh the same except one.
The device enables you to conclude either that the contents of the dishes weight the same or that the dish that falls lower has heavier contents than the other.
