Balance Beam Scale Riddle 7 Marbles

If it s not completely clear how we can make the assumption that the bad coins is in group 7 8 9 when the scales balance remember we know there is a bad coin there has to be we have eliminated the other two.

Balance beam scale riddle 7 marbles.

2 8 of them are exactly the same weight. Split the marbles into 3 groups with 4 marbles each. Weigh 7 vs 8 if they balance then 4 is the odd light ball or the heaviest of 7 vs 8 is the odd heavy ball. Pick 2 groups and use the scale to determine which group contains the heavier marble.

That is a small dish hangs from each end of a rod that is balanced in the middle. If the 2 groups weigh the same the heavier marble is in the 3rd group. A real weight balance or scale looks slightly like the apparatus i drew above. If 3 6 12 is heavy then either 6 is the odd heavy ball or 1 or 2 is the odd light ball.

You can put things in the little buckets and the scale will tip to the heavier side. These differ from puzzles that assign weights to items in that only the relative mass of these items is relevant. The scales are of the old balance variety. 1 you have 9 marbles as seen.

Scale balances means the heavy coin is in group 7 8 9 using one weighing we have successfully narrowed three groups down to one. A balance puzzle or weighing puzzle is a logic puzzle about balancing items often coins to determine which holds a different value by using balance scales a limited number of times. In any case on to the riddle.
