Evaluate the focal length of the lens, Physics

Assignment Help:

An object is placed 25.0cm from a thin converging lens. A screen is positioned so that a sharp image of the object is seen on the screen. When the object is moved 4.0cm closer to the lens, the screen must be moved 3.0cm farther away from the lens in order to retain a sharp image. Determine the focal length of the lens.(What is the focal length of the lens?)
