A glass sphere having refractive index (...

A glass sphere having refractive index (3/2) is having a small irregularity at its centre. It is placed in a liquid of refractive index `(4)/(3)` such that the surface of the liquid is at a distance r above the sphere, where r = 20 cm is radius of the sphere, where r = 20 cm is radius of the sphere. If the irregularity is viewed from above then what is it's distance (in cm) from the centre where eye will observed the irregularity?
