Solution

The correct options are
A

The image is formed at a distance of 15 cm from the mirror.


C

The image is 1.5 times the size of the object.


D

The image formed is virtual and erect.


Focal length (f) = -30 cmObject distance (u) = -10 cm
Substitute above values in 1f = 1v + 1u
130=1v+110
we get Image distance (v)=15cm
m = vu=1.5
