question

A compound microscope has an objective of 3 mm focal length. The objective forms an (intermediary) image 160 mm beyond the second focal plane of the objective. If the eyepiece alone gives 20x magnification (for the eye focused at infinity) , what is the total magnification provided by the microscope?
