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?

Cannot be determined

None of these

Let the ten's digit be x and unit's digit be 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.
