What’s So Funny Ethel?

Merle was checking out at the grocery store. Ethel, a friendly cashier, said the total was $63.59. He gave her a $100 bill and she began laughing as she counted out his change. Then she gave him a high five and Merle left the store chuckling.

What was so funny?

The amount of change was $36.41, which meant Ethel handed Merle one of everything in her drawer:

$20 bill
$10 bill
$5 bill
$1 bill
A quarter
A dime
A nickel
A cent
———
$36.41

Good ol’ Ethel.

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

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.

No Ears and More Than One Eye

I have no ears, but more than one eye,
Cut me in half, I won’t cry,
Leave me alone and I will die.

What am I?

A potato. The roots growing out of a potato are called eyes, when you cut a potato in half it doesn’t produce any moisture and if you leave a poor potato to its own devices, it will die.

Four Colored Balls in Gym Class

Four different-colored balls are being used in a gym class activity – blue, red, yellow and orange. Each student must hold two different-colored balls, but no two students can have the same two colors (for example, only one student can hold the blue and red ball).

How many students can play the game?

Six. If you prefer math, you can calculate it as 4 combination 2

4! / (2!)^2
24 / 4 = 6

Or you can work it out manually:

1. Blue Red
2. Blue Yellow
3. Blue Orange
4. Red Yellow
5. Red Orange
6. Yellow Orange

What word contains all 26 letters?

Alphabet (unfortunately there aren’t any actual dictionary words with every letter in the alphabet, so this gimmicky, somewhat unsatisfying answer has to suffice).
