Answer:
one possibility: it is said that no work was done because work is only said to be done when applied force provides displacement for a body. if there is no displacement on the body, no energy has been transfered, thus no work has been done, so it might be that the man has not managed to move the bag at all
Explanation:
second possibility: the man moved on a circular path, if he moved along a circular path, then the displacement will be zero as he came back from where he started
hope this is correct-
