Some one ask engineering student to prove this equation 
 ( 10 / 2 ) = 2 
 
 
:Engineering student said  
 It is very easy
 
:(10 / 2 )
 
= TWO / TEN
 
Since, T is a common so it will exclude
 
= WO / EN
 
Now ;) ,
 
(W=23rd letter, O=15th letter,
 
E=5th letter & N=14th letter)
 
= 5+14 / 23+15 
 
= 19 / 38
 
= 2
 
:Engineers are never worried about
 " What is the answer "
 
:They will always ask 
 " Which answer you want "
 
That is Engineer ;)B
