The optical powers of the objective and the eyepiece of a compound microscope are 100 D and 20 D respectively. The microscope magnification being equal to 50 when the final image is formed at d =25 ~cm i.e., the least distance of distinct vision. If the separation between the objective and the eyepiece is increased by 2 cm , the magnification of the microscope will be
