Name: ebenezer Question: 

Hi Ebenezer, The numbers look like X0Y and Y0X where X and Y are digits. One of them is 297 more than the other so the difference between them is 297. Write them down, one under the other, and think about the process of subtraction.  Y0X  297 Since the middle digit of the answer is 9 and not 0 you must have borrowed when you subtracted X from Y to get the first digit of the answer. Thus to get the final digit of the answer (the digit 2) you subtracted Y from X1. Hence X is 3 more than Y. Thus what I see so far is X is 3 more than Y
