Find just one digit (Posted on 2005-11-10) Difficulty: 2 of 5
If ABC+DEF+GHI=JJJ, each letter stands for a different digit, and no number starts with zero, what is J?

Okay, I realized that my reasoning was flawed in that there were other alternatives for the left row, such as:

 

1/2/4 w/ carry of 0 ... J=7

1/2/4 w/ carry of 1 ... J = 8

...

1/3/5 = 9

 

So it was pure dumb luck that the alternatives I allowed for contained the correct one. Move along, nothing to see here. :)
