Question 228574: The sum of the digits of a two-digit number is 14. If the digits are reversed, the result exceeds the original number by 18. Find the original number.

You can put this solution on YOUR website! Okay, this you can solve using the hit and trial method.
Now, since 14 is a sum of two digits and we have to reverse them in order to make a number, none of the digits can exceed 10. Which leaves us with
a) 5 and 9
b) 6 and 8
c) 7 and 7.
All of these add up to 14.
The answer is b). 68-86= -18 (The negative sign denotes that if the digits are reversed, the result exceeds the original number by 18)
The original number is 68.
