Shared Birthdays

In 2012 a class was divided into 2 groups. Their assignment was to find the names of at least 3 children who were born on the same day from 5 different months of 2011. These were the results:

Group 1
August 20: Oliver, William, and Adam.
January 3: John, Alice, and Ken.
September 7: Bruce, Shane, and Peter.
June 11: April, Patrick, and Bobby.
July 19: Trent, Julie, and Charles.

Group 2
March 1: Karl, Willie, and Patty.
February 29: Blake, Kobe, and Wayne.
December 24: Kyle, Chad, and Zoe.
May 12: Matthew, Manny, and Adrian.
November 20: Greg, Fiona, and Elizabeth.

The members of group 2 got an F on the assignment. Why?

Group 2 failed because 2011 wasn’t a leap year, meaning there was no February 29th.

Making Lots of Shirts

In a textile factory, 5 machines take exactly 5 minutes to make 5 shirts. How many minutes will it take 100 machines to produce 100 shirts?

5 minutes. It takes each machine 5 minutes to make a shirt, so if you have all 100 machines running at the same time, they’ll produce the 100 shirts in 5 minutes.

A One Letter Change

At my start I last a mere eleven days,
But change one letter and I’m over 31 years.

What am I?

One million seconds (about 11 1/2 days).

Change the “m” to a “b” to get one billion seconds (about 31.7 years).

It’s rather surprising that a million seconds and a billion seconds differ by such a large duration.

Cornelius and the Flat Tire

Cornelius got a flat tire on a miserable, rainy day. As he was changing it on the side of the road, he placed the four lug nuts in the overturned hub cap. As our dear friend was moving back to put on the spare, he accidentally bumped the hub cap. He watched helplessly as all four lug nuts rolled into a deep sewer and were whisked away. Then our friend had a brilliant solution and within minutes was driving safely away.

What was his solution?

He removed one lug nut from each of the other 3 tires and used them to secure the spare tire, then drove to a tire shop.
