Dear student
 
Here, R.I. = n, A =30o ,i = 60o , e = 90o , let d = angle of deviation
 
We know that, d + A = i + e
or, d = (  60o+ 90o  ) - 30o = 120o
Also,
μ = [ sin (A+d)/2] / sin A/2
Plugging in value in this formula you may calculate the required refractive index.
Hope this clarifies your doubt.
