A. 10,395
B. 15,354
C. 29,313
D. 30,708
E. 41,714


Divisibility rule of 9: The sum of the digits of the number should be divisible by 9

Coming to the options

Option A: 10395, Sum = 18. Divisible by 9
Option B: 15354, Sum = 18, Divisible by 9
Option C: 29313, Sum = 18, Divisible by 9
Option D: 30708, Sum = 18, Divisible by 9
Option E: 41714, Sum = 17, Not divisible by 9. Hence the number 41714 is also not divisible by 9

Correct Option: E

NOTE: this is one of those questions that require us to check/test each answer choice. In these situations, always check the answer choices from E to A, because the correct answer is typically closer to the bottom than to the top.

For more on this strategy, see my article: http://www.gmatprepnow.com/articles/han ... -questions

Cheers,
