My Answer 0213Going from left to right.

Lets consider 4th digit to be x.
now digit 1 is three less than digit 4 ... x-3
which is (digit 4) is 1 more than digit 2. so digit 2 is..x-1
which is (digit 2) is twice than digit 3... so digit 3 is .. (x-1)/2
also digit 3 is 1 more than 1/3 of digit 4 .. so x/3 +1

so digit 3 are :
x/3 + 1 = (x-1)/2--------******
2x/3 + 2= x-1
x=2x/3 + 1
3x=2x + 3
x=3

and digit are 0213
