Magnification of concave mirror = - v/u
      = negative for a real inverted image, the image is smaller when object is farther than center of curvature and more than that of object when object is between center and focus.

      = positive for an erect virtual image, with m > + 1 as image is bigger than object, when object is kept inside focal length.

magnification of a convex mirror =  -v/u
         = always positive as virtual images are formed and erect. These are always smaller than object size.  Hence magnification is less than 1.

From the above 3 cases, magnification of +1/3 in a mirror is only possible for a convex mirror.
