The sum of a two digit number and the number got by interchanging its digits is 121. If the digits of the number differ by 5 then find the number.
----------------
Original #:: 10t + u
Reversed #:: 10u + t
--------------------
Equation:
Sum:: 11t + 11u = 121
Dif:: t - u = 5
-------
Modify::
t + u = 11
t - u = 5
-------
Add and solve for "t":
2t = 16
t = 8
----
u = 3
------
Ans: 10t + u = 83
