Why Skid Mark Why? Part 2

Logic puzzles require you to think. You will have to be logical in your reasoning.

 

Puzzle ID:#24703
Fun:*** (2.91)
Difficulty:** (1.68)
Category:Logic
Submitted By:Question_MarkAsx*****

 

 

 



When Question Mark unlocked the door, he thought that he would see his wallet straight away. But Skid Mark (Question's brother) decided to put the wallet in a safe. The combination is three 2-digit numbers which can be expressed like this:

xx-xx-xx

You are given the following clues to work out the combination:

The total of the three numbers is 39.
The second number is half of the third number.
The first number is the third number minus 1.

Can you find Question's wallet in time? It's all up to you.

Simple and fun = ). I don't know how that other person got 7.5 though...Whatever, I thought it was nice. = ).

Lot's of fun .. a little brain exercise .. and your story entertains .. a great combination for a Bringle puzzle! ?=

Aug 22, 2005

it makes your brain works.....but i solve it with differnt version

7 + (4 x
7 + 32 = 39
first# third# munis 1 8-1 = 7
second# half of 8 is 4
third# is 8

ans: 7 4 8
cool_bisdak
Aug 22, 2005

oppsss....i typo error should be minus instead of munis......
7 + (4x
7 + 32 = 39

ans: 748

first# = third# minus 1 (8-1) = 7
second# = half of 8 is 4
third# is 8

sounds logical

Ok, 15 doesn't have an even 1/2, and what is wrong w/ 20 10 & 9, not neccesarily in that order? If 7.5 was a # I'd a been mo5re entertained...

Wait! maybe I read it backwards!

Guys, "skid mark" has a pretty gross meaning in the UK. Suffice to say, it's not a mark made on a road, but inside your underwear...
Question_MarkAsx*
Aug 22, 2005

I didn't mean to make it that way. Although I do live in the UK so I know.
jabdrAus*
Aug 22, 2005

Aside from all these tire (re)marks, I thought it was a fun teaser. I just used odd# + even# + even#, per the instructions, until they added up to 39. Simple!
AralditeAus*

Very easy if you know algebra.

This one was a good one. I had some trouble with it but got it. Good Job!

Exclamation Mark must be involved because, when I opened the safe the wallet wasn't there.
What are those three stooges going to do, anyways?(asked question mark)

My 7th grade algebra teacher would be very disappointed in me...good teaser!
agdjenn*
Aug 22, 2005

That was easy. (z-1) + 1/2 z + z = 39.
mogur*
Aug 22, 2005

Robin, everyone knows what skid mark means, not just in the UK. And some of us find it rather amusing. Thank you, Question, that was certainly a flashback to Algebra class. And I thought I wouldn't need algebra in real life. This is real life, isn't it?

good one

that was fun! i like ones that have to do with math

Aug 22, 2005

I used the same formula as agdjenn - and got the answer. A great refresher for those of us who have been out of school for a (long) while... and a reminder that things you learn there DO come in handy! Great teaser!!!

Here is a good example of when algebra is useful...great job, and cool names and good idea for a continuation of your previous riddle!

Having just finished with algebra this year, this was extremely easy.

i got this one! this was easy! keep em' coming
teri12265us*

The numbers 0 through 9 are single digit numbers ... they belong in the 'ones column', therefore, "08" is not a valid 2-digit number.
That being the case, 10 is the lowest 2-digit number, and following your equation, 49 would be the correct sum of three 2-digit numbers, which are 19-10-20.

I do like the creativity of your characters' names.
Swordoffury1392*us*
Aug 22, 2005

This was a very simple yet fun teaser. My one comment is that 08, though it may be written with two digits, is still a one digit number. I thought the teaser was good anyway

I think it was really stupid.

That was a great teaser, and algebra really came in handy. The thing is, I always like to do it my way, not the way the formula say! Keep em comin! Good job!

Tricky, but nice!!
tazng00se*

came up with an an answer right away but I knew that 7.5 was not a "real" number to use on a combination lock. I tweaked the numbers just a little and came up with the solution.

Always enjoy the opportunity to set up a simple algebraic equation:
(x-1) + 1/2x + x = 39. Familiar but fun. Thought it might have been better placed in the math category rather than logic.
evil_swim_bunny*
Aug 22, 2005

I didn't use that equation. I used 39=2x+2x+x-1

I love the feel of Algebra coursing hot rivulets of mathematical non-compliance through my brain. This is a ninth grade word problem...

Fun, but not overly difficult.

Great teaser Q Mark! I really enjoyed it (mainly because I got the right answer).

BTW- I second Mogur's comment.

i liked, but i kept on thinking that i was getting it wrong, because i did 8 as one digit, not two. oops!

but it was a good one!

1 word. STUPID!

works better(all solutions are two digit) if sum of three is 49.

I SO think you were cheating to consider the number 8 to be a TWO-digit number!!!

I did not get that one. I couldn't understand how to set up the equation.

Not too difficult, not too easy and lots of fun.

8 is NOT a two-digit number!!!!
Aside from that, it was a good teaser.
One question though...what did he need to find his wallet in time for?
doeheadAus*
Aug 22, 2008

I came up with the right answer but questioned myself because I also said 8 was a ond digit number,but I couldn't come up with another solution.
doeheadAus*
Aug 22, 2008

one not ond
zxyggrhynAph*
Aug 22, 2008

My! That was very easy! Basic Algebra.
And yeah, '08' still qualifies as a two-digit number as far as safes are concerned.
zxyggrhynAph*
Aug 22, 2008

'08' would be imposible if the safe has no zero. Common sense! What's with the hooplah?

Aug 22, 2008

This was simple and it angered me that you call 8 a two digit number.
NDYApeacockAin*
Aug 22, 2008

It was pretty good. I solved it by estimating how much a 1/5 is of 39. I just don't think 8 is really a 2-digit nimber.
NDYApeacockAin*
Aug 22, 2008

Sorry, I meant "number"
pMad*
Aug 22, 2008

But on a safe, the numbers are fixed.

Slot1 Slot2 Slot3 Slot4 Slot5 Slot6

So there are six tumblers and each tumbler must have a digit even if that number is zero.

So, on a safe that already has the tumblers in place, 8 IS a two digit number entered on the tumblers as 08

Too easy with algebra, but still nice!

I'm not fond of this type of teaser. Guess you can say I'm not logical.
Thanks for posting, however.
auntiesisAus*
Aug 22, 2008

I love logic as much as I love algebra, but I too thought 8 was not a 2 digit number. But I stuck with my answer and I was right.
carolynsAus*
Aug 22, 2008

That was fun! I got it in two minutes. I figured that since the middle number was half of the amount of the third & first numbers, it represented 1 part and the first & third numbers each represented 2 parts equalling 5 parts. Divide that into 39 (basically 40) and that leaves the middle number at 8 and the other two were easy to figure out from there. This sounded a lot more complicated than it was.
gaylewolfAus*
Aug 22, 2011

I loved this one! and I was happy that I figured it out. I was determined that I was going to find the correct answer and not quit until I did! Because math equations are not my thing. HUGS to KiPA and AS!
gaylewolfAus*
Aug 22, 2011

Doehead, who cares if this is AROB - it's been 3 years! It's a first for me!
doeheadAus*
Aug 22, 2011

Gee Gayle I haven't even said it was AROB. But whatever you want to call it. It is still AROB. But I still Think your great.
rockstar1009**

I solved it along Carolyn's methods - logically; no algebra involved. The third number had to be even (in order to be halved), and had to fall between 14-18 (1/3 to 1/2 of 39 - anything else would be too small or too great to work based on the given clues).

14 didn't work, but 16 was magic. Fun teaser.
Chobuck*

I'm with Carolyn and Rockstar. I was relatively easy, but fun!

Yes , easy but fun. I still got hung up on 8 being a 2 digit #.

This was even better then part 1! i used algebra too, that did make it very easy.
