Question 1150396
The sum of the digits of a two digit counting number is 15, when the digits are reversed the number is 27 more than the original number . what was the original number?
------------------
Reversing the digits of a 2 digit integer changes the value by 9 times the difference between the digits.
================
T + U = 15
T - U = 3
---------------- Add
2T = 18
T = 9
U = 6
--------
Since reversing increases the value, the Tens is the smaller number.
