NPR Sunday Puzzle (Dec. 13): All The Digits Puzzle

NPR Sunday Puzzle (Dec. 13): All The Digits Puzzle
Q: Name five two-digit numbers that are evenly spaced out — like 32, 34, 36, 38 and 40 — in which all 10 digits from 0 to 9 are used once each. What numbers are these?
The first answer came to me as I was driving and listening to the puzzle. However, as I was typing this clue, I came up with another answer that also works. How to give a clue without giving it away, I don't know.

Edit: The clues were to driving which should have made you think of either a car (ie. Car 54) or golf (ie. 18 holes). Those were the starting numbers of two of the four possible sequences.

The tens digit will either step by 1 (5,6,7,8,9) or by 2 (1,3,5,7,9) always ending on 9. The ones digit will also step by 1 (0,1,2,3,4) or by 2 (0,2,4,6,8) always starting (or ending) on 0. That leads to 4 possible sequences:
Starting with 10 stepping by 22 (20+2)
Starting with 18 stepping by 18 (20-2)
Starting with 50 stepping by 11 (10+1)
Starting with 54 stepping by 9 (10-1)
A: There are four possible sequences of two-digit numbers:
• 10,32,54,76,98

• 18,36,54,72,90

• 50,61,72,83,94

• 54,63,72,81,90

1. Here's my standard reminder... don't post the answer or any outright spoilers before the deadline of Thursday at 3pm ET. If you know the answer, click the link and submit it to NPR, but don't give it away here. Thank you.

2. Blaine, I believe there are exactly three possible correct answers. However, my method could not have been used while multi-tasking in the car. (I think that's called "distracted driving".)In hindsight, I see how two of the answrs might have come to mind relatively quickly (but not to my mind). The third answer has a more complicated pattern.

3. Thanks, Les, for posting this week’s puzzle a day early. Last night, I uncorked a bottle of wine, put on my favorite recording of Eine Kleine Nachtmusik, and had the (an) answer in a few minutes. No computer programs here – just a ball-point pen and a piece of paper.

Chuck

4. As I promised last week, here’s the Stupid Christmas Quiz. I apologize in advance for some of the answers. Have fun :)

1. Where does Christmas come before Easter?

2. What's in December that isn't in any other month?

3. On what side of the house do pine trees grow best?

4. What does a cat get when it crosses the desert?

5. What kind of dance would a snow man go to?

6. Which burns longer – a red Christmas candle or a green one?

7. What two things does Santa never eat before breakfast?

8. How many pieces of candy can you put in an empty stocking?

9. What is an elf's favorite dessert?

10. When is a Christmas cake like a cold windowpane?

11. What can Santa take up the chimney down, but not down the chimney, up?

12. Why does Santa wear red mittens?

13. What state does Santa visit that's high in the middle and round on both ends?

14. How is Santa's sleigh like a track team?

15. What does Santa have all over his workshop?

Chuck

5. Lorenzo, I'm up to FOUR possible answers. I'm not sure I've exhausted the options yet...

6. Blaine, your right! (I missed what was probably the most obvious of the answers!)

7. Blaine, even better: "you're right"!

8. I can only find one true solution (three others looked good but the last interval was wrong and I'm thinking Will won't accept a leading zero - but you never know)

9. Chuck,
While you were listening to Eine Kleine Nachtmusik, I was stressing out driving and listening to my teenagers argue about what radio station we'd listen to when it suddenly came to me in a Halloweenish vision.

10. DaveJ –

In standard western math notation, leading zeros are insignificant and therefore truncated. I.e., “01” is actually "1" and is therefore not a bona-fide two-digit number. “000001” also equals "1" and is not a 6-, 5-, 4-, 3- or 2-digit number. So my two-cents is that anybody who has a starting number of less than 10 is not going to get on Will’s scoreboard this week :)

Chuck

11. If the answers of the most obvious ,IMHO, answer are written in order in a column, a circular path becomes apparent. If the column is totaled, another number relating to a circle is produced which can lead to the middle term. For some puzzles I just don't care how much I give away. They're just too easy to begin with.

I suspect the alternate answers are more interesting than the intended one. I'll work on them when I get home.

12. There are 4 answers if you don't count leading 0s, 8 if you do. Two (four with leading zeros) were obvious to me. One of the others is obvious in retrospect, but wasn't immediately. The final one is less obvious.

13. I wrote a little computer program in Qbasic and confirmed that Blaine and David Stewart were right. Using only numbers that would commonly be regarded as 2-digits (10 through 99), there are four sequences that fit the bill.

Chuck

14. I only came up with two solutions (sans the leading zero). The first numbers in the first solution is the same as the middle numbers in the second.

15. Chuck,

I have most of your quiz answers. I'm still working on 9, 14 and 15.

16. phredp, interesting observation. In fact, of the four possible solutions, two have your middle number in common while the other two have a different middle number in common. So you now know the middle number in each of the four solutions.

17. Now I (finally ) found the four solutions, the symmetry is very nice (increments are a, b, 2a and 2b)
Anyone else think the puzzle was redundantly worded: "Name 5 numbers" and "What numbers are these" ? Jeez we're a picky bunch...

18. Blaine, Regarding Chuck's #15 I think
all workshops have the same. It's not
unique to Santa.

19. One easy solution so I'll stop there. Anyone have some more difficult puzzles to keep us going this week?

Dave's Puzzle #?:

Remove the "The" from the name of a movie. Read the remaining word backwards and get the title character in another movie.

20. Blaine / Geri / All –

Partial answers to the Stupid Christmas Quiz cheerfully accepted :)

Chuck

21. I stopped at two answers. I frankly wish I had waited to send in my answer since the second one I came up with is somewhat more elegant than the first one I came to. But this is a challenge that doesn't depend on inspiration to strike you, it can be done relatively easily with a process of elimination. And if you're bad with math and can't get it that way, WS seemed to give you instructions on how to go out and buy the answer this week. I suspect we'll have a record number of entries, even if Sunday Puzzle fans are more verbal than mathematically inclined.

22. 1. In the dictionary.
2. The letter D.
3. On the outside.
4. Sandy claws ("Santa Claus").
5. A Snow Ball.
6. Neither, they both burn shorter.
7. Lunch and dinner.
8. One, because then it's not empty.
9. ?
10. When it is frosted.
11. An umbrella.
12. To keep his hands warm.
13. Ohio ("O-high-O").
14. ?
15. ?

23. 9. Shortcake?
14. It has runners?
15. Sawdust?

24. All this talk of leading zeros is driving me crazy. You guys have me reaching for my handguns.

-- Other Ben

25. I concur with Dave Stewart, Chuck, et. al.
There are FOUR solutions with two digit numbers (10 to 99). These would be valid solutions to the puzzle.

26. Stupid Christmas Quiz:
12. His black ones are in the wash?
15. A rooftop?

27. Blaine –

Congrats! All good on the Stupid Christmas Quiz except for #15. Any other guesses? My favorite is #4, Sandy Claws :)

Chuck

28. 15. Complete dominion?

29. Dave,
You created your movie puzzle by playing around with the answer to Chuck's puzzle from last week!

30. Ken, I just went back to Chuck's puzzle and you're absolutely right, but it was totally unintentional. That answer must have been floating around somewhere in my brain when I thought this puzzle up. Nice job.

Heres another one that I just thought up:

The nickname of a famous queen is an anagram of the name of a famous king. What are their names?

31. Congrats to all who participated in the Stupid Christmas Quiz! They all got solved.

Well that was blazingly fast and all correct, too. Plus legible the second time around :)

Chuck

38. Blaine, I thought maybe it was one too many cups of eggnog I was drinking!!!

39. The following is a quiz put together by some MENSA women. It was published a number of years ago in PLAYBOY Magazine, of all places. Seems they did a nude / semi-nude shoot of dozen or so MENSA lovelies a while back and the quiz added a "beauty and brains" dimension to the piece. Anyway, I'm upping it here for your enjoyment. I found a few of the questions to be relatively easy. But some were tough and some very tough. Good luck :)

1. I am a man. If Joe's son is my son's father, what relationship am I to Joe?

a) His grandfather
b) His father

9. In the following set of numbers, a rule of arithmetic applies across and down so that two of the numbers in a line produce the third. What is the missing number?

6 2 12
4 5 20

Good work - all correct :)

Here's another oldie but goodie I found on my C: drive...

A Quiz for People (Like Us!) Who Know Everything :)

1. There's one sport in which neither the spectators nor the participants know the score or the leader until the contest ends. What is it?

2. What famous North American landmark is constantly moving backward?

3. Of all vegetables, only a few can live to produce on their own for several growing seasons. All other vegetables must be replanted every year. What are the perennial vegetables?

4. At noon and midnight the hour and minute hands are exactly coincident with each other. How many other times between noon and midnight do the hour and minute hands cross?

6. What fruit has its seeds on the outside?

7. In many liquor stores, you can buy pear brandy, with a real pear inside the bottle. The pear is whole and ripe, and the bottle is genuine; it hasn't been cut in any way. How did the pear get inside the bottle?

8. Only three words in standard English begin with the letters "dw." They are all common. Name them. (No dictionaries now!)

9. There are fourteen or fifteen punctuation marks in English grammar. Can you name them?

10. Where are the lakes that are referred to in the "Los Angeles Lakers?"

11. There are seven ways a baseball player can legally reach first base without getting a hit. Taking a base on balls, a walk, is one way. Name the other six.

13. Name ten or more things that you can wear on your feet that begin with the letter "s."

Chuck

43. Pratik, please read the first comment. The deadline for this puzzle is still a few hours away.

44. Chuck,

Thanks for the puzzles. Did the article say how long it should take to solve the MENSA puzzle? I did the best I could do on your new puzzle without using the internet, so some answers are missing.

1. Boxing
2. ?
3. ?
4. 10 times
5. Jai alai
6. Strawberry
7. The bottles are placed over the baby pears and the pears grow inside the bottles.
8. dwarf, dwindle, dwell, Dweezil Zappa
9. Period, comma, question mark, colon, semi-colon, apostrophe, exclamation point, open parenthesis, closed parenthesis, open quotation mark, closed quotation mark, amersand, @ sign, underscore, hyphen (just guessing on some of these).
10. The lakes in Minnesota (Land of 10,000 Lakes), since the L.A. Lakers relocated to L.A. from Minnesota.
11. Basehit, hit by pitch, catcher's interference, error, fielder's choice, when the cather drops a third strike.
12. Kiwi (?)
13. Shoe, sock, stocking, stilletto heels, sandal, sneaker, support hose, slippers, Skechers, Stride-Rites, snakeskin boots, sweatsocks

45. Back to WS's puzzle

[(1)(2)] The 9's multiplication table occurred too easily to me
and contained (2), my solution to the puzzle. I did fiddle around
later to see how the other solutions found by other more
persistent solvers might be related.

(3)(4) Inverting the units columns of (1) and (2)
provides 2 more solutions.

(5)(6) Since [(1)(2)] together are a series, two more solutions
can be formed by using every other value.
(The same simple thing can't be done with non series [(3)(4)].)

(7)(8) Inverting the units columns of (5) and (6)
provides 2 more solutions.

(1)(3)(5)(7)
09 05 09 01
18 16 27 23
27 27 45 45
36 38 63 67
45 49 81 89

(2)(4)(6)(8)
54 50 18 10
63 61 36 32
72 72 54 54
81 83 72 76
90 94 90 98

46. Dave –

If memory serves, I don’t think the MENSA quiz was timed. It was just to see if you could answer them at all. As for the most recent quiz:

1 – OK
2 – Still open for someone.
3 – Still open for someone.
4 – OK
5 – Not the answer I was looking for. Still open for someone.
6 – OK
7 – OK
8 – OK
9 – You got many but there are still at least four open for someone. BTW, I don’t believe the ampersand, @ or underscore are considered punctuation marks.
10 – OK
11 – You got most but there’s one still open for someone. BTW, the catcher dropping a third strike doesn’t automatically get you on. You still have to “steal” first, i.e., get there.
12 – Not the answer I was looking for. Still open for someone.
13 – You got many but there are still at least four open for someone. BTW, I don’t think I’d count shoe brands, a particular type of skin or sweat socks (in addition to socks). But that’s just me.

Good job!

I found a couple more oldies but goodies, but I think I’ll wait ‘til next week to post them. Meanwhile, let’s get this one put to bed.

Chuck

47. 5. Baseball. Duh.

48. 11. Interference by a defensive player. In the interest of brevity, I didn't want to elaborate on the dropped third strike by the catcher since it's a bit complicated, but I'm aware that the batter still has to reach first before he/she is either tagged out or a player touches first while he/she is possessing the ball.

49. 2. Niagara Falls
3. I believe Asparagus is perennial

50. As for the Sunday Puzzler:

My reasoning was that it makes sense to think of the number as two digits, not a single number. Then you need to increment or decrement each digit during each iteration. Adding 9 to a two digit number will increase the 10's digit by one while decreasing the 1's digit by one. Adding 11 will increase both digits by 1. Those are the two obvious ones. Less obvious initially, to me, was adding 22 will increase both digits by 2 and adding 18 will increase the 10's digit by 2 while decreasing the 1's digit by 2. Using this you can easily construct the proper sequences of numbers by picking appropriate starting numbers.

51. 5. Baseball
9. others off the top of my head: em-dash, en-dash, curly braces, square braces, angled quotes (guilemets sp?), single quotes, slash and solidus.
12. Watermelon?

52. Everything numerical that I have to say has been said.

I came up with the answers using the gaps of 9 and of 22.

When I wrote that I was "reaching for my handguns," that was because 9s and 22s are both popular handguns here in the big bad city. That was my clue.

-- Other Ben

53. My first thought went to multiples of nines (54, 63, 72, 81, 90) and eighteen (18, 36, 54, 72, 90) where the tens digit went up to 9 and the ones digit went down to 0. I shortly realized you could create a similar sequence where both digits went up by either 1 (50, 61, 72, 83, 94) or 2 (10, 32, 54, 76, 98).

So I wonder which of these was "the" set of numbers that is printed in Scott Kim's calendar? Anyone else disappointed that the puzzle given as a reason to buy the calendar doesn't have a unique answer? :-)

54. I just wrote the numbers 1, 3, 5, 7 and 9 and then, next to each of them, in order, wrote 0, 2, 4, 6 and 8.

55. All –

As to the Know Everything Quiz:

2. Right – Niagara Falls.
3. Right – asparagus is one. There are still two more perennial vegetables.
5. Right – baseball.
9. Right – dash, slash and brackets are all good. There is still one more punctuation mark.
11. There is still one more way to get on first.
12. The only-served-fresh vegetable or fruit I have in mind remains unnamed.

As to Will’s puzzle:

I took a different tack to solve it: a tiny little computer program written in QBasic. For those of you using Windows as your operating system you probably already have QBasic on your C: drive and never noticed it. It’s almost always on the original installation discs. Anyway, if anyone has QBasic and would like to see and run the program, it’s only about 50 lines of code. I’ll be happy to post it. It solves the puzzle essentially instantaneously.

Chuck

56. I am stunned with the immediacy of the Internet and a somewhat amazing coincidence that just occurred!

You remember the How Many Quiz I recently posted here that begins 1 W on a U, 3 B M (S H T R), etc? I had originally run across it decades ago. It’s so old it looks typewritten, not word-processed. I long ago lost my copy but fortunately, I had given a copy to one of the secretaries at work. She still works for me and she still had her copy. We got it out, went over it and added a few new items. Then I typed it into Word, edited some of the clues and changed the order the entries were in. Finally, I posted it on the puzzle blog. The date and time stamp of my posting was December 16, 6:54PM PST.

Last night, I got an e-mail from my daughter. She was forwarding me an e-mail she had received from an acquaintance. The date and time stamp of her friend’s e-mail is December 16, 9:04 PM PST. It contained the exact same quiz – word for word, letter for letter – that I had posted a little over 2 hours earlier!!!

What are the chances of that happening? And I wonder how many degrees of separation there were.

Chuck

57. I've also wrote a little program to check my answers to the original puzzle. It's in Perl.

9. As for punctuation, I can't believe I forgot about the ellipsis. I use that one all the time. Silly me…

58. 12. Watermelon (I cheated and used the internet).
