Answer 255 satisfies the condition so it's right but 128 is also satisfying condition so it is also a possible answer:
if we pick up 128 oranges.
on 1st gate he will give 64
on 2nd gate he will give 32
on 3rd gate he will give 16
on 4th gate he will give 8
on 4th gate he will give 4
on 6th gate he will give 2
on 7th gate he will give 1
64+32+16+8+4+2+1=127

finally 1 orange will remain with him.

255 is correct Answer. Please read the question properly. look at the fist and third conditions.
1) You must give oranges, 1/2of how much u have and also 1/2 of one orange
3) Don't cuting the oranges
If 128 then how will u satisfy above condition with out cutting the orange. And also look at the second condition.
2)- after giving the portion of last (seventh guard) guard u have balance only one orange.
