You have 8 coins that all look  exactly the same, two of them are fake,one of these two fake coins is 0.1gm more than a normal coin, whereas the second coin is 0.1 gm less than a normal coin.

 With howmany weighings can you find them out  using a balance scale?

Spoiler for My answer

TBNZH

Spoiler for Explanation

Assigning each letter its numerical value A=1, B=2, ... Z=26 we get the following square:

 

24 11 18  5 12
 7 19  6 13 25
 ?  ?  ?  ?  ?
 3 15 22  9 21
16 23 10 17  4

 

Every row adds up to 70. Numbers 20,2,14,26 and 8 complete the magic square making every row, column and diagonal add up to 70. These numbers translate into letters TBNZH.

Yes...thats right....it is the magic sguare

Hi my friends...I`ve prepared a nice puzzle to you..
Here we go:-
Cut 9 pieces of paper,write a number on each one of them,from 1 to 9,put them in a pot,put the pot on a table.
Your aim is to arrenge these numbers on the table in this order: 123456789
according to the following rules:
1- you can choose any number to be the first number, and put it on the table.( for example I choose number 4).
2-take a second number and compare it with the number on the table, if.. 2nd>1st....put it to the left.
if 2nd<1st...put it to the right.( in my example, if I choose 7...I`ll get 74.....but if I choose 3.....will be 43).
3-now whenever you have an even amount of numbers on the table( two numbers,4,6,or 8), you should insert any number you want
between them,just in the middle.(in my example, if I want to choose 5,so I should put it in the middle to get 754,,,or 453).
4- you are allowed to take any number from the table and put it back in your pot. but to put any number again on the table,you should follow the rules.
5-to put the 4th number, you should compare it with the middle number( in my example...with number 5), if the choosen number>than
the middle number....put it to the left, if the choosen number < than the middle number...put it to the right.(in my example, if I choose
number 9,,so 9>5...I`ll get 9754,,,or 9453).
6-as in step 3.
7-whenever you have an odd amount of numbers on the table(one number,3,5,7,or 9),you should compare your choosen number with
the middle number, if your choosen number>the middle number....put it to the left.
if your choosen number<than the middle number.....put it to the right.


Have a nice time

The teacher asking a student:
Which is the farthest , the moon or Australia?
The student(after a short time): Australia
Teacher(surprised) : why.. !?
Student: because we can see the moon, but we can not see Australia.

I think it is very useful to add a small (paint) program ,either to edit new puzzles or to answer others.
Thanks

Hello...God bless you all
I believe in God for a very simple,uncomplicated reason,
If anyone asks me a very easy mathmatical question, e.g.(If the sum of 2 numbers is 17 ,and the difference between them is 1...what are the numbers?)
My brain will assume the first number to be (X) , simply, because I don`t know the answer, now....Is (X) a real number?....YES it is.
Does it exsist?...YES....and so on.
Old people saw all around,human,creatures,earth,stars.....without knowing where did they come from....so they assume that there is someone who creates all these things, they gave him the name(GOD) insted of (X)...So he is real and exsists.
