										Hey kashif U can first find minimum deviation of a prism by using formula ü=[sin{(A+d) /2}]/sin (A/2)..  Where d is the minimum deviation and u is its refractive index...  Then U can use the concept that at min deviation angle of incidence is equal to angle of emergence..  So use the formula d=i+e-A...  Since i=e..  Then u can find i...  Hope U like it...
