A jeweller has nine golden statuettes, which belong to a new line of high-design ornaments. He knows that one of them is a little heavier than the others, but the difference isn’t such that you can tell by eye.
He will therefore have to use a very sensitive double scale to find out which of them he can sell at a higher price.
With a careful calculation of the number of statuettes to place on each arm, what is the minimum number of times he will have to do this operation to be 100% sure of identifying the one that weighs the most?
Choose from 1 to 10.
