14. If the two-digit integers M and N are positive and have the same digits, but in reverse order, which of the following CANNOT be the sum of M and N ?
(A) 181
(B) 163
(C) 121
(D) 99
(E) 44


Hi,

the answer is A) but I think both A) and B) can be answer cause both can not be devided by 11..... can anyone confirm??

Your strategy is the same as I used...Are you sure the answer choices mention 163 and not 165?
