Answer 2

Answer:

we are given that the image has a size of 10cm n is at a dist. of 20cm from d mirror of focal length 10cm. So, we can directly say that the image is at C or Centre of curvature.

We know that whenever the object is at C d image will also be formed at C but real and inverted.

Therefore, d image distance is also 20cm.

Hope it helps sis.
