In a compound microscope, the objective lens and eyepiece have a focal length of $\mathrm{0.95 }\mathrm{}\mathrm{c}\mathrm{m}$ and $\mathrm{5 }\mathrm{}\mathrm{c}\mathrm{m}$ respectively and are kept at a distance of $\mathrm{20 }\mathrm{}\mathrm{c}\mathrm{m}$. If the last image is formed at a distance of $\mathrm{25 }\mathrm{}\mathrm{c}\mathrm{m}$ from the eyepiece, calculate magnifying power.
