It's correct. Only 3,6,7 are out of place. You need to swap them to make them occupy correct location. Their AND value is 2 which is the answer. Code for reference : 158037115

    but there is no way to make them occupy correct location with the value 2.

      Swap digits 2,7. Now swap digits 2,3. Now swap digits 2,6. Now swap digits 2,7
