Here's my question - Jim turned the pages of a book he was reading. Each page had a 3-digit number. The sum of the digits on page M was 6. The sum of the digits on page N was 7. What are the two possible page numbers?

Hi hi, the answers given to me was M = 222 and N = 223, but i can't figure out how to derive these answers?

Get three digit numbers whose sum of digits is 6 and whose sum of digits is 7. Then choose the ones that fit the given criteria.
