#164:Weighs and Means
There's a game we used to play at school in the labs, where
we tried to make the most elaborate set of weights and rods
that'd balance perfectly. Yes, I had a lot more free time back
then...
Here are two diagrams of balances I've set up, with the weight
labels removed. Each weight is always a whole kilo - 1kg,
2kg, 3kg, etc. Assuming that the strings and rods have no
weight, can you figure out the value of the weights that I've
numbered?
If you use the lightest possible combination of weights,
there's only one correct solution...
