2 steps. 1. Put 3 balls on each side of the scale measure( [123], [456] ) If each group of 3 is equal: 2. Place the remaining two balls on the scale - measure( [7], [8] ) If each group of 3 is not equal: assuming [123] is heavier than [456] 2. Take 2 balls from the heavier group from step 1 and place them on the scale. measure( [1], [2] ) If they are equal then [3] is the heaviest Less

do 3, 3 first. if wieght is diff then one of two left out. => twice usage of scale. if one side is heavier the other from 3,3 then other three and 2 left out are same. then put 1,1 and leave one out. => twice usage of scale. Less

↳

Well, why not take 4 and 4, weight it and pick the heavier scale, then break the 4 into 2 groups then take the heavier one, then break the 2 balls into 1 and 1 and you will get the heavier ball... the heavier ball is picked out. Less

↳

break the 8 balls into 4 groups of 2 each - weigh each group and pick the heaviest out of each - 4 weighings, then take the 4 heavy balls and break it into 2 groups .... weigh each group like before - 2 weighings, then take the 2 last balls and weigh to get the heaviest ball .... so in all 7 weighings Less
