Mixed Animals for $100

At the market you can buy a cow for $10, a pig for $1 and 8 hens for $1. How many animals would you need to buy to get 100 mixed animals for exactly $100?

7 cows, 21 pigs and 72 hens. The trick to this is finding the combination of cows and hens with the same cost and quantity since pigs are already equal. The magic combination is 7 cows and 72 hens, giving you 79 animals that cost $79 ($70 + $9). Then you just add 21 pigs to get to 100 animals.

The Most Impressive Boundary

The most impressive boundary’s not a wall.
It’s not a manufactured thing at all.
Moving towards it won’t reduce the gap
and nothing marks its presence on a map.

The horizon.

Harvest Though No Grain

I harvest you, though you’ve no grain,
I reap you in the wind and rain,
You bleed not but your soft meat
And nectar makes a sweetest treat.
What am I?

A clam or oyster. You harvest clams or oysters on the beach or go diving, and the beach is often windy and rainy. Neither bleeds but are known for having, soft, slimy meat, and people often drink the “clam nectar” or “oyster juice”.

In Oven But Not Baked

What must be in the oven yet can not be baked?
Grows in the heat yet shuns the light of day?
What sinks in water but rises with air?
Looks like sand, but is fine as hair?

Yeast.

I’m Usually Quite Pleasant

I’m usually quite pleasant
As you roam and play,
But if you look into my eyes,
I’ll not look away.

Once you turn away from me,
I’ll attack if I stay dry,
Better grab a pail of water,
I’ll not stop until I die.

What am I?

An Enderman, from Minecraft.

Enderman are normally passive, but they become hostile if a player looks directly at them. The Enderman will stare back until the player looks away, and then attack the player. A bucket of water is the best way to defeat an Enderman.
