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

If you can hard boil a Kiwi bird egg in 20 minutes, how long would it take to hard boil four Kiwi bird eggs?

20 minutes. You can boil them all at once in a large pot.

The Secret of the Chalk Emerald

A dear old relative passed away recently and her family gathered for the reading of the will. The final item was the Chalk Emerald, a priceless gem. The will bequeathed it to whoever determined where it was hidden. The only clue was it was in a cylinder surrounded by a thousand squares. A young lass of barely six immediately piped up saying she knew where it was hidden and she was correct. Where was the hiding place?

In a roll of toilet paper.

Mark suggested two alternative solutions: A cylindrical chimney or a well, the squares being the bricks. Although most bricks aren’t square, it’s conceivable I guess.

An Oddly Priced Fish Shop

A fish shop with odd pricing sells fish for the following prices: A trout costs $20, a salmon is $19, and a plaice comes in at $16. Using their pricing logic, how much would they charge for a mackerel?

$13. The price is calculated by using the position in the alphabet of the first letter of the name of the fish. An Albacore would be $1, a Bandfish would be $2. Note, I do not recommend using this pricing strategy unless you find yourself with an assortment of cheap Zebrafish.
