1/u + 1/v = 1/f .........u - object distance, v - image distance, f - focal length.
1/v = 1/f - 1/u
= 1/15 - 1/10 = -5/150
v = - 30 cm
M = Magnification = -v/u = 30/10 = 3.
The image will be at a distance 30 cm, and 3 times the size of object and will be virtual, erect, since it's placed between the pole and focus of the mirror
