A convex lens produces a real image `m` times the size of the object. What will be the distance of the object from the lens ?

A convex lens produces a real image m times the size of the object. What is the distance of the object from the lens ?

A convex lens of focal length f produces a virtual image n times the size of the object. Then the distance of the object from the lens is

A concave lens of focal length f produces an image (1//n) times the size of the object. The distance of the object from the lens is :
