By doing this we will know if 4 or 5 is heavier. If they balance out, then 6 is the heavier one. If {1,2,3} and {4,5,6} balance out, then we know either 7 or 8 is the heavier one. Weigh both of them to find out which one is heavier.
How do you find out the heavier ball in a set of 8 balls 7 are of equal weight?
One of the ball is heavier than rest of the 7 balls, which all are of equal weight. You have to find out the heavier ball by using two arm balance scale a minimum number of times.
What is the most efficient way to figure out which marble is heaviest out of a set that contains 9 marbles?
you have 9 marbles, all of them identical except one of them is slightly heavier than the rest. in order to determine which is the heaviest, you have a balancing scale, however you are only allowed to use it twice.
Which ball is heavy?
Excellent: Now we know that the heavy ball is A or B or C. To figure out which one it is, weigh any two against each other — say, A versus B. If one or the other is heavier, then you’ve found your answer. If the scale balances, then you know the heavy ball is C.
Which is the heaviest ball?

Which ball is the heaviest?
Is the 8 ball heavier in pool?
It is much harder than regular pocket billiards (like 8-ball and 9-ball). Carom balls are slightly larger than ordinary pool balls. They are 2 7/16″ in diameter and weigh about 7.5 ounces. Compare this to the smaller pool balls which are 2 1/4″ and weigh about 6 ounces.
How to find the heaviest marble with 8 marbles?
Suppose you have 8 marbles and a two-pan balance used to compare the weight of 2 things. All of the marbles weigh the same except for one, which is heavier than all of the others. How can you find the heaviest marble if you are only allowed to weigh the marbles 2 times?
How many marbles are in each side of the scale?
To do this, put 3 marbles in each side (3 left, 3 right, 3 unused) If the scale tips to a side, we know that group of 3 has the heavy marble. If it does not tip to a side (if it balances), we know the “unused” group of 3 contains the heavy marble. Keep the heavy group of 3 marbles and discard the rest.
How can you tell how many marbles are in a bucket?
1) You have 9 marbles (as seen). 2) 8 of them are exactly the same weight. The remaining marble is slightly heavier than the others. You don’t know which is which. 3) You are allowed to use/set the scale TWICE in total. In other words, you get to take 2 measurements (or “comparisons”) here. 4) Each “bucket” has enough room for multiple marbles.
What does 9 marbles and a weight balance look like?
So, you have 9 marbles and a balance. Or weight scale. Or weight balance. Or whatever you want to call it. Because I draw like a 2 year old, some clarification as to what you see above. A real weight balance (or scale) looks slightly like the apparatus I drew above.
