simple explanation :
Basically this program indicates fake results for any given number.This will very useful to fool your friends.This program is based on JavaScript.Basically this program cheek the last digit of entered number and give you your result from 10 different sets or marks(in this case out of 30).Basically this works by the function Know(n1,n2 ) .Here document.write is used which completely overwrite the page and look like it delivered from the server(but it is not so).So enjoy & make your friends fool.
