Heya.......!!!
It is given that least distance of distant vision of average person is 25 cm , in order to view an object with magnification 10 .
Here , v = D =>> 25 cm and u = f
But the magnification m = v/u =>> D/f
=>>> f = D/m =>> 25/10 »» 0.025m
Power P = 1÷f ( in m ) = 1/0.025 =» 40 D .
Power of microscope = 40 D .
Hope it helps u ^_^
