A magician asked a spectator to think of a three-digit number ABC and then to tell him the sum of numbers ACB, BAC, BCA, CAB, and CBA. He claims that when he knows this sum he can determine the original number. Is that so?

Yes I read the problem wrong.
I was thinking ABC was added to its permutations.
