The answer is 1.67.
Apply the formula apparent depth= d/2 ( 1/n1+ 1/n2 )
where d is the real depth and n1 and n2 are the refractive indices...
Apparent depth =Real depth1.5n
=d/21.5n=d3n
Total apparent depth:
Total apparent depth=d2n+d3n =5d6n
But, total apparent depth is d/2.
Hence,
5d6n=d26n=10 n=106 =1.67..
Hope this helps you..
