Source: Manhattan prep
Target question: Is the integer X between 20 and 26 inclusive?
Statement 1: x is multiple of 9
Some possible values of x include: 9, 18, 27, 36, 45, 54, ....
Notice that NONE of the possible x-values are between 20 and 26 inclusive.
So, the answer to the target question is
NO, x is NOT between 20 and 26 inclusive
Since we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: x = 18
if x = 18, then the answer to the target question is
NO, x is NOT between 20 and 26 inclusive
Since we can answer the
target question with certainty, statement 2 is SUFFICIENT
Answer: D
