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

I Make You See the Beauty of Nature

I make you see the beauty of nature through colors,
My name makes things weigh less
And I have no weight at all.

What am I?

Light. Without light you wouldn’t be able to see anything. And light is made up of all the colors of the rainbow. Adding light to a word can mean it weighs less and light has no mass.

5 25 325 4325

Given

1 = 5
2 = 25
3 = 325
4 = 4325

What does 5 equal?

54325. Rather than being a mathematical solution, the answer is derived by prepending (putting in front of) the value on the left side of the equation with the previous answer. So for 3 you take 25, the previous answer, and put 3 in front, giving you 325. Then you put 4 in front to get 4325 and lastly, put 5 in front to get 54325.

No Head On Which A Hat To Place

I always run but never walk,
I sometimes sing but cannot talk,
No head on which a hat to place,
You always look me in the face.

What am I?

A clock. It runs all the time, it “sings” for hourly chimes, cuckoos or alarms, it doesn’t have a head (but does have hands) and you look a clock in the face to tell the time.
