6- A jeweller has nine gold figurines, from a line of high-value goods. He knows that one of these figurines weighs more than the others,
but the difference is too small to tell from looking at them.
He must use a carefully calibrated two-armed weighing scale to find
out which figurine he can sell for a higher price.
Taking care with how many you place on each side of the scales,
what is the minimum number of times in which you would have
to weigh the figurines, in order to be 100% sure which one weighs
the most?
