Easy magical Triangle

18 October 2014 - 09:06 AM

Hi dear friends...

 

1- Draw an equilateral triangle ABC.

2- Make two points on each side to get (ABC+6point= 9 points), with 4 points on each side.

3- Give the numbers( 1 to 9 ) to these points, so that the sum of  4 numbers on each side  is the same.

i.e.

A+point1+point2+B= B+point3+point4+C= C+point5+point6+A

 

 

have fun

Three persons( A,B,and C) are not allowed to speak,but to raise a hand  refering to ( Yes or No ), you don`t know which hand means Yes,and which means No.

How can you know  the persons which is which by asking only three( yes or no) questions.

You may ask one ,two or all of them...as you like.

any  question should be asked to a single person.


Amount of air in a glass

06 July 2014 - 01:32 PM

If we have an emty cylindrical  glass  on a flat table with a dice inside it , naturally, it will contain an amount of air inside it.

Now , if we invert this glass upside down on the table, leaving the dice still inside it but landing on the table , will the amount of air inside the glass changes?

If yes, would it be more or less, and why?

If no...why?
