Let's start with this one:

Replace the letters with numbers (0-9), to give a meaning to the equations:

RE + MI = FA

DO + SI = MI

LA + SI = SOL

RE = 27

:mitch:

Hm... Nobody yet? It's not difficult! No Algebra needed. Not comparable with that problem from Singapore!

Still working on it, yet I'm sure someone will beat me to the punch. Tic-toc, Tic-toc,...

You failed to mention the prize.  :wink:

R=2, E=7, M=5, I=6, F=8, A=3, D=4, O=0, L=9, S=1

RE=27, MI=56, FA=83, DO=40, SI=16, LA=93, SOL=109

Thus:

27 + 56 = 83
40 + 16 = 56
93 + 16 = 109

Here's an age-related math puzzle:

Corrine asked her Granny how old she was. Rather than giving her a straight answer, she replied:

"I have 6 children, and there are 4 years between each one and the next. I had my first child (your Uncle Peter) when I was 19. Now the youngest one (Your Auntie Jane) is 19 herself. That's all I'm telling you!"

How old is Corrine's Granny?

Ok, this is easy.
Corrine's granny had her last baby (Jane) at the age of 39 (19+4+4+4+4+4). Now Jane is 19, so Corrine's granny is 58 years old (39+19).  :dance:

Make the number 30, using the digits 6, 5, 6, 5, and any mathematical symbol!  :thumbsup:

6 x 5 X (6 -5) = 30
(6 - 5) =1 so the above becomes 6 x 5 x 1 or 30

Draw two lines as shown
A + D is obviously equal to C
D and B are corresponding angles in right triangles with a base double the height, therfore D = B
therefore A + B = C

P.S. There are other answers to this puzzle as well.

A poor woman and a rich woman are talking about music.

The poor woman says she has studied music and can name a song with any name in it.

The rich woman says "OK, if you can find a song with my son's name in it, I will give you a thousand dollars. His name is Panteleimon-Rigas."

The poor woman gives her answer and is instantly $1.000 richer.

What was her answer?

roughly translated to English   
In Greek the meaning of the name Panteleimon is: Merciful.
Rigas  from a medieval Greek personal name, meaning 'king',

'Merciful King' by Robbie Seay Band a Christian rock group

Pete! WOW!!!

I admired your reasoning!!!!!  :goodie:

But my aim was not to teach you Greek! I just chose a difficult name, not connected with any known song!!! I could not imagine that there was a possibility for anyone to find a song with ... Panteleimon-Rigas!!! BRAVO!!!!  :dance:

Anyway, Merciful King is not the answer! I'm taking back Panteleimon-Rigas, and instead, I give you ... Marcello-Tzavarellino.

Hi, Pierre. I noticed your puzzle, but ... it has many English for me! :) Maybe during summer I will try it!

But here is another one!

1. Take your shoe number.
2. Multiply by 5.
3. Add 50.
4. Multiply by 20.
5. Add 1015.
6. Substract your birthday year.

What is the answer?? Let's see as many answers as we can!!!   :D

972

1010

128 ( UK feet measurements )
303 ( Europe measurements )

Well, I think that you should check again. There is a mistake in your results.  :)

The ''miracle'' of this trick is that if you perform correctly the equations, you get a number where you can see the number of your shoe and your age.  :D

The question is: why?  ;)

Quote from: DR M on January 17, 2016, 05:18:17 PM

Because both your shoe size and the year of your birth are included in the data.
The rest is just there to confuse the unwary.

Well, yes! You are a mathematician, Sir!  :)

I don't think I'll find something to make it difficult for you! Although, I'll give it a try.  ;D

What about this one:

What is the number where the car is parked?

Numbers on parking places are normally sequential, and oriented to be viewed from the aisle. To read them in the above, you need to turn the picture upside down.
You get...

86, car, 88, 89, 90, 91
The number under the car is 87

Disclaimer: I'm not literate in whatever language that is. I assumed, they want you to guess the number under the car.

Yes, it's Greek. That is why I wrote under the picture the question in English.

Well, now, I suppose that the only puzzle remaining, is my computer's foolishness!!! Can you say why ''she'' so problematic?  :o

Peter is copying of John and John is copying of Jack. Peter is a good student, but Jack is not. Is a good student copying of a student who is not good?

    A: Yes
    B: No
    C: Cannot be determined

C. Can not be determine
John's skills as a student are unknown.

We don't know, but this info is not necessary.  :)

Pete!, are you here??  :)

Quote from: DR M on April 03, 2016, 05:09:37 PM

I deliberately didn't answer this one because, it can be looked at in different ways, depending on how you interpret it.

Literal interpretation - "Unknown" because the good student is copying from a student of unknown capabilities.

Results oriented interpretation - "From a poor student", because that's where the work originated.

It could also be argued that a "good student" would not be cheating, and that the original premises are flawed. A poor student is copying from another poor student, who in turn copied from the only student who didn't cheat.

You have to take it as a math logic problem. Don't try to interpret the scenario with any other kind of logic.

THE PROBLEM:

Peter is copying of John and John is copying of Jack. Peter is a good student, but Jack is not. Is a good student copying of a student who is not good?

    A: Yes
    B: No
    C: Cannot be determined

THE SOLUTION:

The most common answer to this problem is C (cannot be determined), because we don't know John's skills.

BUT:

Do we need this information?

There are two possibilities about John's skills: being a good student or not.

If he is a good student, then he is copying of Jack who is not, so the answer is A (YES).

If he is not a good student, then Peter, who is a good student, is copying of him, so the answer is A again (YES).

Conclusion: The answer is A (YES). Information about John's skills is not necessary.    :)

Hello, LzD Friends. How are you?? Here is summer again.  :)

This is another puzzle for everyone:

I hope that yesterday was tomorrow, so today was Saturday...
What day I did this statement??

Monday

If it's Monday, yesterday was Sunday
If Sunday could be tomorrow, today would become Saturday (what's being wished for).

BTW: The diction of the question makes it confusing. (Was this a translation)?
I assumed you meant "On what day did I make this statement?"

I refuse to play/comment until the syntax is correct.  ;)

Actually, I copied it from a site and I didn't notice that there was a mistake. I apologize for the confusion. English is not my strength.  :)
And yes, the correct answer is Monday.  :D

Can you escape from this Christmas decorated house??

A brick weighs 1 kg plus the half of its total mass. How much the brick weigh?  :)

2 kg

Right. :)

Now I have to translate a problem from Greek, with a little help from Google translation, and I hope I will manage to give you the right meaning.

A spy is standing outside a camp and trying to hear from the guard and the inmates at the camp, what is the password and the pass phrase (please correct me here, I don't know the correct words) , in order to get inside it. After two people entered the camp, the spy excited realizes that he learned what he was asking for.

What was said among the guard and those who entered the camp:


A.  12!
       6!

B. 6!
    3!

So the spy moves forward and faces the guard. He knows that the guard will tell him a number and he will have to answer exactly the half. Very simple!!!

-Ten! the guard says.
-Five! the spy answers!

And then, to his surprise, the guard is arresting him! WHY? WHAT HE SHOULD ANSWER?

Hmmmm. The description (translation) is confusing, yet I'll take a stab:

18 ?

(12+6=18; 6x3=18)

2 ?

(12 divided by 6; 6 divided by 3)

3

Twelve = six letters
Six = three letters
Ten = three letters

Yes, 3 is the correct answer, as the trick has to do with the number of letters in each word-number.

In Greek the logic behind the explanation is stronger, as the problem talks about three camp's visitors.

A.
Guard: 12 (δώδεκα, twelve > 6 letters)
Visitor: 6

B.
Guard: 6 (έξι, six > 3 letters)
Visitor: 3

C:
Guard: 8 (οχτώ > 4 letters, does not much with the english word eight which has 5 letters, so I left this behind).
Visitor: 4

Great. Do I win a prize? How about a week on Zakynthos or Cepholonia next August, all expenses paid? I was married in Greece, to a Greek woman. Real Greece! I prefer the Ionian Sea.

Please let me know.
