of microscope and telescope both decreases.
of microscope decreases and of telescope increases.

Solution :M.P. of microscope = `(LD)/(f_of_e)` . In this, if only ) increases and other remains CONSTANT then M. decreases.
M.P. of telescope = `(f_o)/(f_e)`. In this, if `f_0` INCREASE with same `f_e`, then M.P. increases.
