## Weighty Wine

How much does a bottle of wine weigh if it is 1 kilogram plus half its own weight?

2 kg.

If we let half of the bottle’s weight be “n”, then we get the following equation: n/2 + 1kg = n (the bottle’s weight).

Solve for n:

n/2 + 1 = n

1 = n/2

2 = n

I’ve seen others like this and I have to say that they all confound me. I’m a college graduate and still it alludes me. Why???

@Jude

2kg is the only value for which the description holds true. Since it’s 1kg plus half its own weight, that 1kg must be the other half, meaning it weighs 2kg.
