Since the sign is negative, the image is real and inverted. Since the magnification is more than 1, it is enlarged.

So, does diminished image have magnification in decimal form like 0.2 or something like that?

The image formed by the lens will be diminished.
- When the value of the magnification is less than 1, the image formed is always diminished.
- Since, the value of the magnification is negative, the image must be real and inverted.
- We can also conclude that the lens given in the question is a convex lens as a concave lens gives a diminished image but it always gives a virtual and erect one.
