The Average of Three

There are three numbers. The first two are 2/3 and 3/4.

What does the third number have to be to make the average of all three be 2?

4 7/12

In order for the average of three numbers to be 2, they must all add up to 6. That gives you this equation:
2/3 + 3/4 + n = 6

Solve for n = 55/12, or 4 7/12.

Four Walls and a Bird

A man walks out of a house that has four walls all facing north. A bird walks past him. What kind is it?

A penguin. If all four walls face north the house must be at the southernmost point of the earth. Really, any native antarctic bird would work.

This brain teaser is quite similar to the guy whose house walls face south and sees a bear, then you’re asked the color of the bear. The bear would be white (a polar bear) as they’re the only bears indigenous to the north pole. A lawyer would claim it’s all circumstantial evidence and the bear could be an imported brown bear. The lawyer makes a valid point.

Wolves and Owls

You are in the woods with owls and wolves. There are 22 eyes and 32 legs. How many owls and wolves are there?

5 owls and 5 wolves, (not 6 owls because 2 of the eyes and legs are yours).

2 * owls + 2 * wolves = 20 eyes
2 * owls + 4 * wolves = 30 legs
owls + wolves = 10 eyes → owls = 10 – wolves
owls + 2 * wolves = 15 → 10 – wolves + 2 * wolves = 15 → wolves = 5
owls + 5 = 10 → owls = 5
