I did this similarly but didn't want to post too soon: a+b+c+d+e = 100  Since the sum of three of these must be 40, they must all be 20 or one must be 50.  Since the sum of three of these must be 30, they can't all be 20, so there's one 50.  Now a+b+c+d = 50, and the sum of three must be 30 so there must be at least one 20. and the sum of three must be 40 so there must be at least one 10.  Now a+b = 20, which only has one solution. katie
