If you want to find any solutions that would fit, you need to look at what you are dealing with first. For example, you need to consider the largest even number. From 0-9, how would you tackle that? It's simple. You can use any two numbers, so go with the easiest two. 98. So you can't have 9 and you can't have 8 any more. Next, you need to consider the largest odd number. 75. Then, you need to consider the smallest odd number, which would be 13. After that, you need to look at the largest multiple of 5, which would be 60. You see, if I hadn't have looked at the options I would've come across that one and realised that I hadn't got a 5 or a 0. Finally, you need to look at the last one, which is the number closest to 50. You've only got two numbers left, so it would be 42. I'm very sorry for if there are any typos in my explanation.
