Detailed Solution

Concept- Both the focal length and the image distance are considered positive for a convex mirror. Convex mirrors usually create a distorted but upright image. We will compute the image distance using a mirror formula and the type of image created using a magnification formula.
Equation used:
Mirror formula,

Magnification,

It is to be remembered that a convex mirror always forms the virtual, erect and diminished image.
Given: Object distance,

Focal length,

To find: Image distance,

From mirror formula:

Hence image will be formed

beyond the mirror, i.e virtual magnification

Hence, the correct answer is 0.6, erect and diminished.
