Answer : 3 9 4Explanation :
from 1 and 2 we get that 2 is not in the code.
from 2 and 4 we get that 4 is in the code and not in middle position.
from 3 we get that 4 is in the last place of the code.
now from 1 we get that 9 is in the code and the center number of the code.
so from 5 we get that 6 is not in the code and
hence from 3 we get that 3 is in the code and has to be in the 1st place.
Hence the code is 3 9 4
