the bottom of 2 metre deep water tank has a gold ring there by what distance would the ring appear to be raised when viewed by a person from the top of the tank

We can write

$H=nh (1)$

where H is the real deep, n is absolute refractive index of water, h is the visible deep

Using (1) we get

$h=\frac {H}{n} (2)$

h=1.5 m
