Because we are dealing with a Remainders question, each of the terms X and Y are given in terms of the divisor 11, and we are asked for the one that could NOT be X + 2Y:

the correct answer must be the one that gives us a different remainder when divided by 11, compared to the other 4 answer choices

We can directly move to the answer choices and check the remainder of each answer choice when divided by 11

(A) 120

(1 + 0) - 2 = -1

-1 + 11 = remainder of 10


(B) 196

(1 + 6) - 9 = -2

-2 + 11 = remainder of 9


(C) 219

(9 + 2) - 1 = remainder of 10


(D) 351

(1 + 3) - 5 = -1

-1 + 11 = remainder of 10

(E) 560

(0 + 5) - 6 = -1

-1 + 11 = remainder of 10


Each answer will yield a remainder of 10 when divided by 11 EXCEPT answer (B)

Answer must be (B) 196
