Sunday Times Teaser 2722 – A Simple Sum

by Ian Kay

Published Sunday November 23 2014 (link)

I have written down two three-figure numbers and one four-figure number: between them they use each of the digits 0 to 9 exactly once. In fact the four-figure number is the sum of the other two numbers.

If I told you how many of the three numbers were even, then it would be possible to work out the four-figure number.

What is it?
