You Have 8 Marbles One Is Heavier

You have 8 marbles.

You have 8 marbles one is heavier.

For convenience sake let s name the balls 1 8. If when comparing the 6 marbles we find that both. From the heavier three put one aside and place one marble on each tray. You are given 8 identical looking balls.

If one side is heavier you found the one. Seven of the marbles have the same weight and one marble is heavier. 7 marbles weigh 1 ounce each one marble weighs 1 5 ounces. Suppose you have 8 marbles and a two pan balance used to compare the weight of 2 things.

This 9 balls puzzle problem is very similar to 8 balls weight puzzle where 8 identical looking balls are given and one of the balls is heavier than rest of the 7 balls. Keep the heavy group of 3 marbles and discard the rest. If one is heavier than the other then we ve succeeded in just two weighings. You have a weighing scale that consists of 2 pans but the scale is only good for 2 total weighings.

One of them is heavier than the rest of the 7 all the others weigh exactly the same. You have eight marbles. If equal then the one you set aside is the heavy one. You a provided with a simple mechanical balance and you are restricted to only 2 uses.

You have to put all the 100 marbles into the jars. Flag as inappropriate flag as inappropriate. Then in the second weighing we can compare 2 of those 3 marbles to each other. If they are the same weight then the 3rd is the heaviest.

No matter which case happens you weighed marbles only twice and found the heavy one. Explain how you can deter mine the heavier marble by using a balance scale exactly a. Since we now have 3 marbles 1 of which is the heavy one put 1 in each side 1 left 1 right 1 unused set the scale again. If it tips to a side we know that marble is the heavy one.

If instead it balances we know the one unused marble is the heavy one. You have 9 marbles one of which is heavier and a set of scales what is the minimum number of times you must use the scales to find the heavier one. If one side is heavier than the other then we only have 3 marbles left. Find the heavier ball.

All of the marbles weigh the same except for one which is heavier than all of the others. How would you find the heaviest marble if you are only allowed to weigh the marbles 2 times. You are unable to determine which is the heavier marble by looking at them.
