A door, a body, and a knot can be this.

Double. Double doors, a stunt double (for an actor) and a double knot. And there’s also the double rainbow :)

What Digit Does Each Letter Represent?

This is what you know:

1. Each letter represents a different digit from 1 to 9
2. The total of each row is 17.
3. (B × B) + B + F = A
4. C × F = EF (a 2-digit number, not their product)

A B C
D E F

What digit does each letter represent?

A = 7
B = 1
C = 9

D = 8
E = 4
F = 5

A + B + C = 17
D + E + F = 17
B2 + B + F = A
C × F = EF

To begin with, B has to be a 1 or 2 or else A wouldn’t be a single digit. Plug in B = 2, gives you 6 + F = A, meaning F and A can only be (1,7) or (3,9). To get 17, C would have to be 8 or 6, but those values don’t work for C × F = EF. So B must be 1.

2 + F = A means F and A can be (2,4), (3,5), (4,6), (5,7), (6,8) or (7,9). To get 17 on the top row, the only option that leaves C as a single digit is F = 5 and A = 7.

C × F = EF
9 × 5 = 45, so E = 4 and D = 8 to make the second row equal to 17.

Up A Hill

Up a hill,
Down a hill,
Over them I may roam,
But after all my walking,
There’s no place like my own.

Your home.

A Third As Old

Barry is 67 years old. His daughter is 43. When was she 1/3 as old as him?

31 years ago.

Here’s one way to solve it.

Let x = how many years ago

We get this equation: 67 – x = 3 × (43 – x)

Solving for x gives us 31.

Six Nine Twenty-Seven

What is N?

6, 9, 27, 54, N, 2241

675.

The next number in the sequence is n squared minus m or f(n,m) = n2 – m
f(6,9) = 62 – 9 = 27
f(9,27) = 92 – 27 = 54
f(27,54) = 272 – 54 = 675
f(54,675) = 542 – 675 = 2241

Can’t Be Touched, Can Be Felt

It can’t be touched, but can be felt.
It can’t be opened, but can be gone into.
Those who seek it always find it under something,
yet it moves from place to place.

Shade. You can’t touch shade, but you can feel its coolness. You can’t open shade but you can go into it. If you’re looking for shade it always has to be underneath something to block the light and shade moves as the light does.
