Doughnuts

[Dee-M-See]

You have 8 Doughnuts all weigh the same amount except one which is heavier,you have a balance scale
Whats the minium amount of weighings required for you to pick out the heaviest Doughnut every time

[sniffa]

three

[sgeandhu]

3, split into 4 v 4, split heaviest 4 into 2x2, split 2 into 1x1

[Salty]

two

Weigh three doughnuts against three
If both batches weigh the same, discard and keep last two, and compare them in a second weigh
If one batch of three heavier, keep that, and weigh two of them against each other - if one heavier, that's it, else pick the third one

Thank you Salty that seems to be the correct answer
