The sum of the digits of a two-digit number is 15 and the difference between the digits is 3. What is the two-digit number?	Pick one:
A) 69  B) 78  C) 96  D) Cannot be determined  E) None of these
Let the ten's digit be x and unit's digit by y   Then, x + y = 15 and x - y = 3 or y - x = 3   Solving x + y = 15 and x - y = 3, we get: x = 9, y = 6   Solving x + y = 15 and y - x = 3, we get: x = 6, y = 9   So, the number is either 96 or 69.   Hence, the number cannot be determined.   ANSWER:Cannot be determined
