Answer by vleith(2983)   (Show Source):
You can put this solution on YOUR website! Let the integer be represented as XYZ
You are told X is even - so X can be 0,2,4,6 0r 8
Y is 6 less than X. Thus X must be either 6 or 8 for Y to be valid
Z is 3 less than X. So Z is either 3 or 5
You are told the number is not divisible by 5, so Z cannot be 5. Z must therefore be 3
Which makes X 3+3 = 6
Which makes Y 6-6 = 0
The number is 603
Total of X+y+Z = 9
Answer is A
