Question

when we see our image keeping the concave side of spoon towards us we obtain aVIRTUAL N INVERTED IMAGE.how is this possible?

Answer 1

A spoon has two surfaces. First is concave and the second one is convex. Thus, it acts both as a concave and a convex mirror. Thus if we see our face on the concave surface, a real and inverted image is formed.
Since spoon is small in aperture and the focal length is also very small . So, the image formed is real and inverted.
