Ray optics, lens maker's formula with different medium on either side

What do we take as relative refractive index? Why is the solution taking it as air for all 3 lenses?

because the object is in air

oh its refractive index of lens / refractive index of medium where object is? i just phrased it as "surrounding medium" so got confused alr if one lens formed a virtual object that was in another medium?

in the same setup? lenses ke beech mei gap hona chahiye tab right?
Nimboi [ping if answering]
no just in general one lens forms an image that acts as a virtual object for another, but that virtual object is in another medium

if someone (who studied properly) maintained their mental composure then possible 99.5+
