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.

Nine-Letter Word, Common as Air

A nine-letter word, common as air,
When each letter’s cut, a new word to pare,
Take a letter each round and continue to one.
Name the word and the path and then you’ll be done.

Surprisingly, there are several nine-letter words that can have one letter removed in each round to make a new word all the way to one letter, which must be ‘a’ or ‘i’. Startling is the most common answer, but I’ve included the other words I’m aware of. I don’t include plural words, like cleansers, drownings, splatters, starvings, trappings and wrappings because it’s kind of cheating.

startling
Remove the l to make starting (or remove the t to make starling)
Remove the t to make staring
Remove the a to make string
Remove the r to make sting
Remove the t to make sing
Remove the g to make sin
Remove the s to make in
Remove the n to make I

splitting
Remove the l to make spitting
Remove the p to make sitting
Remove a t to make siting
Remove the first i to make sting
Remove the s to make ting
Remove the g to make tin
Remove the t to make in
Remove the n to make I

stringier
Remove the r to make stingier
Remove the i to make stinger
Remove the t to make singer
Remove the r to make singe
Remove the g to make sine
Remove the e to make sin
Remove the s to make in
Remove the n to make I

strapping
Remove the s to make trapping
Remove the t to make rapping
Remove the p to make raping
Remove the r to make aping
Remove the a to make ping
Remove the g to make pin
Remove the p to make in
Remove the n to make I

A Most Unusual Paragraph

This is a most unusual paragraph. How quickly can you find out what is so unusual about it? It looks so ordinary you’d think nothing was wrong with it – and in fact, nothing is wrong with it. It is unusual though. Why? Study it, think about it, and you may find out. Try to do it without coaching. If you work at it for a bit it will dawn on you. So jump to it and try your skill at figuring it out. Good luck! Don’t blow your cool!

The most common letter in the English language, the letter e, is not found in the entire paragraph.

A Corny Question

A merchant has 21 sacks of grain: 7 full, 7 half-full and 7 empty. He wants to divide them equally among his three sons. How can he do this, without transferring any grain between sacks, so each son has the same quantity of grain and number of sacks?

We know each son must end up with 7 sacks and 3.5 sacks of grain, since (7 sacks + 7 half sacks) / 3 = 3.5 sacks each.
There are two solutions.

Solution 1
Son 1: 3 full, 1 half-full and 3 empty.
Son 2: 3 full, 1 half-full and 3 empty.
Son 3: 1 full, 5 half-full and 1 empty.

Solution 2
Son 1: 2 full, 3 half-full and 2 empty.
Son 2: 2 full, 3 half-full and 2 empty.
Son 3: 3 full, 1 half-full and 3 empty.
