One Six Seven Nine to Twenty Four

Given the numbers 1, 6, 7 and 9, find an equation that equals 24. You may only use each digit once.

91 – 67 = 24 or
(9 – 6) x (7 + 1) = 3 x 8 = 24 or
6 x √9 + 7 – 1 = 18 + 6 = 24

I Start Out The Same As Others

I start out the same as others,
Then grow to four legs and four arms,
And two hearts beat inside,
Until the separation.

What am I?

A pregnant woman is like other women, then the baby forms, and then is delivered.

Dead At The End of An Alley

A man is found dead at the end of an alley. A detective who enters the scene sees the letter X and immediately knows who killed the man and why. What did the detective conclude?

The alley is a bowling alley. The man who was killed was a pin spotter (an old profession where they would reset the pins by hand). The X was the marking on the score sheet for a strike. The detective saw the letter X and knew that the person bowled last, got a strike, and was due to bowl again. But they bowled before the pin spotter could get out of the way.

Glittering Points Downward Thrust

Glittering points
That downward thrust,
Sparkling spears
That never rust.

An icicle.

Dry As a Bone

Milton was out for a walk when it started to rain. He did not have an umbrella and wasn’t wearing a hat. His clothes were soaked, yet not a single hair on his head got wet. How did this happen?

Milton sadly suffers from alopecia, more commonly known as baldness. The old coot was as bald as a ping pong ball, leaving not a single hair on his head to get wet.

Related Strangers

A man gets off the bus looking for an address and approaches a couple walking in the same direction for directions. The woman says they’re going that way and take him. Along the way the man asks if they’re related. The woman grins and says, “We’re not strangers. This man’s mother is my mother’s mother-in-law.” The man is confused but doesn’t say anything. When he gets back home he tells his wife about the conversation and she can’t figure it out either. They decide to ask their lawyer and he eventually works it out with pen and paper. How are the couple related?

The couple is either a man and his daughter or an uncle and his niece.

Consecutive Christmas Caroling

My family sings Christmas carols at the hospital where my wife works.
We do this every year and since we started, have not missed a single year.
The next time we do this will be the 18th consecutive Christmas.
My 15 year old daughter has been every time.

How is this possible?

She was born in March 1999 so the first year she came was December 1999 (before her 1st birthday).
Her first time was when she was 0, second time when she was 1, third time when she was 2, etc…

Now that she is 15, she has been 16 times. Oh and of course she was also present in December 1998 in her mum’s belly, due to be born the next March.

So, a total of 17 times and next time will be the 18th.

Thanks to Michael for submitting this real-life brain teaser about his family.

I Change Stature As I Age

I change stature as I age, but my importance does not differ by age. My importance is manifested mostly when with my boss. When we part, I am of no importance.

What am I?

A pencil. It gets shorter with use, but is no less important. Its impact is from the person using the pencil to write or draw. Without them, the pencil is just an idle tool.

Thanks Keller!

Copying Cassette Tapes

Joe and Andrea want to copy three 60-minute cassette tapes. They have a 2-cassette recorder to copy the tapes, allowing them to copy two tapes at a time. Each side takes 30 minutes to be copied, so two tapes can be copied in an hour and the third will take another hour. Andrea bets Joe she can copy all three tapes in 90 minutes. Does she win the bet?

In the first 30 minutes Andrea copies the A sides of tape 1 and 2.
In the second 30 minutes, she copies tape 1 side B and tape 3 side A (finishing Tape 1).
In the last 30 minutes, she copies tape 2 side B and tape 3 side B.
