If the focal length of the 1st lens is 10cm and it is at a distance of 20cm,it me that the object is placed at 2F1.
An object placed at 2F1,the image will form at 2F2 and the distance of the object from the lens will be too 20cm as the object was.
Since the distance between both the lens is 30cm,then the distance between the second lens and the image formed will be 10cm.
The image formed by the 1st lens will act as an object for the 2nd lens.
The focal length of the 2nd lens is of 10 cm. But the object will be too at a distance of 10cm. Therefore the object will be at F1 and the image will be at infinity.
Hence, the final image will be at infinity.
