Best ResponseYou've already chosen the best response.0you have a point there, the version i remember did not place a restriction of 4 weights to the solution.

Best ResponseYou've already chosen the best response.0You can weigh a 2 by putting a three on one side, and a one on the other. Ditto for 5 (9 vs 3+1)

Best ResponseYou've already chosen the best response.0It's an old problem from pre revolution France. The conventional way of thinking was that the mass being weighed on the balance had to be measured with a number of the weights on the opposite side. The solution here is to realise that you can also add weights to the side being weighed. So 1 is weighed conventionally but 2 is weighed with a 3 on one side and a 1 being added to the side being weighed, etc 1, 1 2, 3, 1 3, 3 4,3,1 5,9,3,1 6,9,3 7,9,1,3 8,9,1 9,9
