I am a two-digit number greater than 50. Add my digits together and you get 11. Subtract the smaller digit from the larger, and you get 5. What number am I?
83
Let the digits be x and y. We know x + y = 11 and x - y = 5. Adding these gives 2x = 16, so x = 8 and y = 3. Since the number is greater than 50, the tens digit must be 8, giving 83.
