Heavier Ball

[Kirono23]

How will you solve this?

Just pick them all up separately, and see which one weights more. You dont even need the weight machine

How will you solve this?

Is the weight machine pan type - where you can compare weights of two groups?

If it is then divide the balls into three groups (3,3,2)

Put the groups of threes on the pans - then think.....

But thinking is so painful! Is there another way? Can't you just give me the formula?
