ANSWER
Object distance u=−10 cm
Radius of curvature of concave mirror R=−15 cm
Thus its focal length f=

⟹ v=−30 cm
Magnification m=

∴ m=

−(−30)
=−3
Negative sign indicates that the image formed is inverted in nature.
Magnitude of magnification is greater than 1 which indicates that magnified image is formed.
