You have 4 weights weighing 2,3,5 and 7 pounds. The problem is none of them are marked. What is the fewest number of weighings you need using a balance scale figure out which weights are which?

quite easy actually, you need 0 weighings to get the weights. You can tell the differences between the weights by just using common sense, meaning put the weights in your hands and use them to tell the difference
