    As none of the trials has any bulls and 4 appears in evey position 4 is incorrect. So the tree numbers are 2, 3 and 5 in some order.

    As 3 is not in the correct position when it is in position 1 or 3 it must go in position 2. So the number is *3*.

    We see immediatly now that the 5 goes in position 1, and so the number is 53*, and so the 2 goes in position 3 and the final answer is 532.
