If the two-digit integers A and B are positive and have the same digits, but in reverse order, which of the following could be the sum of A and B?	Pick one: A) 29 B) 30 C) 31 D) 32 E) 33
A two-digit number "cd" can be expressed algebraically as 10c+d.   The sum of A + B = (10c+d)+(10d+c)=11(c+d).   The only answer that is a multiple of 11 is 33.   The answer is 33.
