Ten Times Two is 0218

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = ?

2840.

This makes the first column the start of the Fibonacci series: 0, 1, 1, 2.
The second column is the even numbers: 2, 4, 6, 8
The third column is counting up by ones: 1, 2, 3, 4
And the last column is the answer in the first row in reverse: 8, 1, 2, 0.

Don’t ask what 50 × 2 equals. I have no idea. :)

Thanks to Jim for helping with the solution.

An Urgent Phone Call

A man was working the night shift when he received an urgent phone call, giving him information that caused him to dash home at breakneck speed.

On bursting into his bedroom quite breathless he found his informant was quite correct. His wife was in bed with someone he had never seen before.

However, far from being angry, he greeted them both with a smile and a few hours later brought them both breakfast in bed.

What is the explanation for this odd behavior?

His wife had just given birth.

Nearly Hanging

A prisoner is told, “If you tell a lie we will hang you; if you tell the truth we will shoot you.”

What can he say to save himself?

You will hang me. If they hang him, then the statement was true and they could only hang him for telling a lie. If they shoot him, then it makes the statement a lie and they were only to shoot him for telling the truth. An alternate solution is to say, “You will not shoot me,” leading to the same quandary for the killers.

A Slight Inclination of the Cranium

A slight inclination of the cranium is as adequate as a spasmodic movement of one optic to an equine quadruped utterly devoid of any visionary capacity.

Translate this rather strange sentence into one that is more sensible.

A nod is as good as a wink to a blind horse.
