Assuming each of the given digits can be used only once, the answer is 24. If not, the answer is infinity.
Since the order of the digits does not matter there are only five combinations: 1234, 1235, 1245, 1345 and 2345.
10% off of 1245 = 1120.5 = 1245 - (10% * 1245) = 1245 - (0.10 * 1245) = 1245 - 124.5 = 1120.5
1245 is divisible by 5.
1245/10 = 124.5
2000 - 1245 = 755
1245 + 130 = 1,375
