If 45 is added to a two digit number, the result is a number w/ the same digits, but reversed. The sum of digits is 11. What is the original number?

Question

Can i see two equations

Answer 1

We only have three choices: 29, 38, 47. Any more and adding 45 will take us above 99. any less won't let us add up to 11.  If you take a look at our three choices, you can probably see which one fits the criteria.

2 + 9 = 11

3 + 8 = 11

4 + 7 = 11

 

29 + 45 = 64

38 + 45 = 83

47 + 45 = 92
