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

The Truck and the Plane

A delivery truck from the post office is sent to the airport to meet a cargo plane at its planned arrival time. The plane lands ahead of schedule and its contents are brought toward the post office by bicycle. After a half hour, the bicycle meets the truck and the mail is transferred.

The truck returns from the post office 20 minutes early. How early did the plane arrive? (Assume all transactions are instantaneous)

The delivery truck arrived back 20 minutes early, so it would have taken 20 minutes to go from where it met the bicycle to get to the airport and back. Therefore, the bicycle and truck met when the truck was 10 minutes from the airport. Adding those 10 minutes to the 30 minutes the truck had already driven to meet the bicycle means the plane arrived 40 minutes ahead of schedule.

A Third of the Way But Only Halfway There

You’ve traveled a third of the way, yet you’re only halfway there.

Where are you going?

Hint: The answer applies in the US but not in Europe.

You’re in a build headed to the fourth floor. When you reach the second floor, you’ve gone one floor and have two more floors left, so you’re 1/3 of the way. But at the same time, you’re on the 2nd floor and have two more floors to get to the 4th floor, thus you’re halfway there.

This doesn’t work in Europe, because they typically refer to the “first floor” as the ground floor, and the first floor is one story up.

Thanks to Danny Llinas for submitting this.

The Case of Wesley and the Broken Window

Wesley’s mom discovered a broken window in the living room and went to ask Wesley about it. Wesley told her he had been playing Monopoly with his friend Cindy. She asked him what his last roll had been and he said, “A one”. She immediately knew he was lying.

How?

Monopoly has two dice, and the lowest number two dice can roll is 2. The window repair came out of Wesley’s allowance and he stopped throwing his baseball in the house.
