One day Santa was bored and so decided to entertain himself by racing some of his reindeer.  The first 100 meter race was between Dasher and Dancer, and Dasher  won by 10m.  The next 100 meter race was between Dancer and Prancer, and Dancer won by 10m.  Finally, Dasher ran against Prancer in another 100m race.  By how many meters did Dasher win?

Oh, and the answer is not 20m.

As ever, please do NOT post your answer but feel free to say if you think you have solved it and how long it took.

Solution on Monday.  Have a good break!

Oh, and if you want to be the life and soul of the party over the next few days, you might find this video useful….

Yes I got this one in about a minute. Have a cool Yule Richard!

2. Took me about five minutes to write down the names…lol…too many …. ‘hers and ‘cers ….and once cleared my head of the similar sounding names I had my ahh mmm ooh yeahhh I got it… I think…lol…

3. Anonymous says:

I have it answered – assuming the reindeer run consistently at the same speed. Not 100% sure, but confident in my method.

4. rmb says:

Needed pen and paper and took about two minutes. Also enjoyed the quiz here after so many weeks.

5. RedEaredRabbit says:

Got it in less than a minute.

Merry Christmas, by the way.

6. M says:

Got it in less than one minute, using excel.

nice puzzle.

Merry Christmas

7. Think I’ve got it. Isn’t Excel marvellous 🙂

8. DrGreen says:

I got it in 3 minutes … and really not 20m. Nice puzzle!

9. I had to use a calculator but got it in under a minute. Nice puzzle!

Omg I think I may have actually solved this one! It’s always been hard for me to figure out how to interpret problems like these and find the operations to perform, so if I actually did this right, I would be so excited. If I have the right answer, it took me about 4-5 minutes.

11. safc4ever says:

What sort of METERS are they? Gas, Electricity, Water?

Maybe Richard means METRES – The SI Unit of measure. This is the International ‘Metric’ unit and has a standardised spelling. I suspect that some countries spell it Meter, but if they do, then it is through blind ignorance.

I do not think Richard is an Ignoramus, however he appears to have been lax this week in not proof-reading the puzzle (obviously sourced with the mis-spelling intact) before posting it.

As it stands, with the glaring error of asking by how many measuring devices a race is won, there cannot be any real answer, so maybe we are looking for a surreal answer. My answer in that event would be that Dasher beat Prancer by ‘A Fish’.

Happy Christmas one and all!

You self-righteous little twerp.

2. safc4ever says:

Nice to see someone is lacking a sense of humour!

3. TS says:

BS tiny twerp, Mètre is a unit of measure not of language.

Richard may have it wrong in English, but almost all other languages spells it differently.

12. Tessa K says:

Too busy thinking about elf jockeys to do the maths.

13. Alex says:

Not sure if I used the right method, but I’ve arrived at an answer after about a minute of using paper, pen + calculator!

14. Mark says:

You know… I’m going to have to wait for Monday. 😦

I don’t think you can answer this with the information given.

1. David D says:

Yes you can. Keep trying (some maths involved!)

15. Kittyd66 says:

I’ve got it- sorted between patients in my Christmas Eve GP surgery

16. D says:

Done with thumbs and forefingers in about 15 seconds! 😀

17. Savant says:

Excel? Calculator?

The only reason I needed a pen and paper was the confusingly similar names.

18. Got it! Pen and paper, some recurring digits but they shouldn’t affect the approximate answer too much.
Merry Christmas one and all!

19. Cary says:

I think I got it, using fractions and the like. In about 2 minutes

20. Cosmin Romania says:

1-2 minutes, did the math.

21. michel says:

Merry Christmas !

Thanx for all those puzzles.

22. llemirtrauts says:

After replicating the experiment with three genuine reindeers, an atomic clock and a lazer and a quadratic equation, I have ascertained that the answer is indeed not 20 metres.

23. Victoria says:

It depends if they’re being ridden or chasing some spring-loaded lichen! Let’s face it-anyone being forced to carry Santa is at a disadvantage compared to being ridden by Mary Christmas (if she’s good enough for the Catholics >;OP) or any of the elven helpers.

That said ~ I still keep getting 20m. I think I need to use paper and different sounding names.

Merry Christmas one and all, and thank you Richard for your dedication to the Friday puzzles and for usually being up at 5am to post them. X

About 1 minute to work out what the question was actually saying, and a minute to do the maths.

25. JayCee says:

Of course it is not 20m that is what i figured out in about 20sec (most of the time verifying the odrder of the names. Than i spent 5 minutes to develop the math to verify what method could be used in excel. And than i put the math in some braincellsto verify my first result (which was based on similarity and therefore more logic than calculation). And yes, it was the same.
Wow i am always astonished how the brain can work in so many different ways.

Merry Christmas – let the feast begin!

26. Jeremy says:

Well.. assuming that reindeer accelerate to full speed instantaneously, and that Dasher was not fatigued from his earlier race… 😛

27. Oh yeah, don’t forget to account for the 10 pounds each reindeer had to carry to prevent them from becoming airborne during the last 10m of the race!

Merry Chrismas, Happy Holidays and Seasons Greetings! From all of mine to all of yours!

28. UXO says:

Under a minute. Too algebraic/formulaic. No real insight required.

29. Nisarg says:

i got its answer in a minute and i think it to be right. it just required a pen and a calculator.

30. The other Matt says:

Short answer in one minute (new best highscore for me). Then about five minutes to check its correct.

31. The other Matt says:

Curious, because normally its won by xx seconds(time) and not won by xx meters (distance)

32. took me few minutes, i was surprised it was not 20 at first but the calculation showed its not 20 🙂

33. Mr. D says:

Got it after a few minutes of being confused. I think in future I should just go straight to the pen and paper to save time, it always helps me think more clearly.

Merry Boxing day everyone! 🙂

34. Joao Pedro Afonso says:

Good Puzzle. Perhaps 30 seconds, counting with time to get the right number by head.

Almost forgot to check these puzzles since the last ones didn’t deserved the name of puzzles. That, and the ongoing Christmas.

Merry Christmas and happy good year!!!

35. christine says:

In a collaborative effort we believe we have the right answer within 2 min but then re thought the matter again and now we two of have two different answers ..

curiouser and curiouser !
