How should we put the sign conventions if the type of lens is not mentioned in the question?

There will be some other things given in the question that would help you determine the type of lens. For example, if the image is real, it would always be a convex lens; if the virtual and magnified, it would be a convex lens again; if the image is virtual and diminished, it would always be a concave lens.
