Hard Boiled Kiwi Bird Eggs

If you can hard boil a Kiwi bird egg in 20 minutes, how long would it take to hard boil four Kiwi bird eggs?
Note: Kiwi birds are about the size of a chicken, but they lay eggs that are close to the size of an Ostrich egg. So one would assume they must take a long time to hard boil.

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

4 Is Cosmic

1 is 3,
3 is 5,
5 is 4,
4 is cosmic.

What is 6? And what is meant by cosmic?

6 is 3 of course. Because six has three letters.

One = three letters
Three = five letters
Five = four letters
Four = four letters

Cosmic is a number that has the same number of letters as the value. Four is the only number I’m aware of that has this property.

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.

Come For a Ride

I go up, but at the same time go down,
Up toward the sky and down toward the ground,
I’m present tense and past tense too,
Come for a ride, just me and you.

What am I?

A see-saw.

Seen in the Water

I am seen in the water
If seen in the sky,
I am in the rainbow,
A jay’s feather,
And lapis lazuli.

Blue.

Three Kinds of Apples

Three kinds of apples are mixed randomly in a box. How many apples must you take out to be sure of having at least two apples of one kind?

Four. If the apples are A, B, and C, it’s possible that you could take out one A, one B and one C with three apples, but the fourth apple must be one of the three kinds.
