Hint
Look at Digit 3 first.
Answer
6394.
Reasoning
Labelling the clues:
Digit 2 is smaller than Digit 4
Digit 4 is two thirds of Digit 1
Digit 1 is two thirds of Digit 3
Digit 3 is three times Digit 2
Using (4), Digit 3 can only be 3, 6 or 9 (as it's 3 x Digit 2).
Therefore, using (4), Digit 2 can only be 1, 2 or 3.
Using (3), Digit 1 can only be 2, 4 or 6 (as it's two thirds of Digit 3).
However, using (2), the only possible value for Digit 1 that we can find two thirds of is 6.
So, using (2), Digit 4 is 4.
So far, we have 6??4.
Using (3), Digit 1 is two thirds of Digit 3, so Digit 3 must be 9.
And, by (4), Digit 2 must be 3.
Giving 6394.
