In a class, Budi's score is greater than Doni's. The sum of Adi's and Doni's scores is greater than the sum of Budi's and Coki's scores. Meanwhile, Doni's score is greater than two times Budi's score substracted by Adi's score. Determine the median of those four students' scores.

All I know, was, by using their initials that:
B > D
A + D > B + C
D > 2B - A

And by using the second and third info I got that their score from lowest to highest is either C, D, B, A or D, B, C, A. However, I met a dead-end after that. Please someone help me.

I suspect that there is something wrong with the problem. It is true that A>B>D and C fits in somewhere below A, but even if you find some numbers that work, you can always get a different answer by adding the same thing to each of A, B and C. Here are some numbers that work.
A B C D Med
88 68 82 65 75
78 52 46 37 49
93 59 32 49 54

Thank you everyone who has helped me with this question. I have asked this question in 4 different forums including this one and all confirm that it is impossible to find the exact number of the median's value.
