As far as this question is concerned, it is flawed..

a) statement I gives z as 13..
So 13+17 is div by 5... Ans NO
Sufficient

B) statement II gives X as mutiple of 25 and. Hence of 5, so 17 div by 5 leaves a remainder 2
Ans YES
Sufficient

D but both give contradictory answers ..
What is the source? Please don't post from it.

please correct me if I am wrong, Data sufficiency statements should give same answer is it a required condition?
you should get one answer whether yes or no but only one from each statement then it should be sufficient.
this is my understanding.

Hello

On GMAT, in data sufficiency questions, whenever the answer is 'D', both statements should give the same answer. So if the question is of the type which bears a YES/NO answer, both statements should either give YES or both should give NO. This is the way GMAT forms its questions.

Also, even the information in both statements should be consistent and shouldnt be contradictory.
