If the image of the head is bigger than it must be a concave mirror. Concave mirror produces virtual, erect and enlarged image behind the mirror when object is placed between its pole and focus.

If the middle portion of her body is of the same size then it must be a plane mirror which produces same size virtual and erect image as object.

Since the image of leg is smaller than the leg itself, it must be convex mirror because convex mirror produces diminished image of the object.

So, the order of combinations for the magic mirror from the top.

1. Concave mirror

2. Plane mirror

3. Convex mirror
