Let the integer be represented as XYZ
\n" ); document.write( "You are told X is even - so X can be 0,2,4,6 0r 8
\n" ); document.write( "Y is 6 less than X. Thus X must be either 6 or 8 for Y to be valid
\n" ); document.write( "Z is 3 less than X. So Z is either 3 or 5
\n" ); document.write( "You are told the number is not divisible by 5, so Z cannot be 5. Z must therefore be 3
\n" ); document.write( "Which makes X 3+3 = 6
\n" ); document.write( "Which makes Y 6-6 = 0
\n" ); document.write( "The number is 603
\n" ); document.write( "Total of X+y+Z = 9\r
\n" ); document.write( "\n" ); document.write( "Answer is A
