The solution to this one is rather hard to explain so be patient with me. S is obviously a large number. We have less than 1100 to add to SEND to get a five digit number. Next subtract 100E from both sides.
Lets rearrange that a little.
R must be 8 for the sum to have hope to reach 90. For this to work E and D will need to be on the large end and Y on the small end. The third option is the one that works.
