I added up the number of students in each of the sports (30,40,25). That's 95. We know there's 23 students who don't play those sports so 67 remaining. That means there's a 28 student overlap. Adding up the given overlaps (15,10,8) gives you 33. So the overlap for those is 5. I subtracted from the appropriate sections of my diagram as I went.
You are genius, could please upload your diagram again because I can't display picture.
