Refractive Index of glass with respect to water can be calculated by 

(Refractive Index of glass with respect to air) × (1/Refractive Index of water with respect to air)

We know that,

Refractive Index of glass with respect to air = 4/3

Refractive index of water with respect to air = 3/2

Hence, Refractive Index of glass with respect to water = (4/3) x (2/3) = 8/9.

Akshay Venkatesh, a renowned Indian-Australian mathematician, is one of four winners of mathematics’ prestigious Fields medal, known as the Nobel prize for math. New Delhi-born Venkatesh, 36, who is currently teaching at Stanford University, has won the Fields Medal for his profound contributions to an exceptionally broad range of subjects in mathematics.

Given 

445 of 229.79 = ? of 2398.51

$$\begin{gathered} 245 x 230 = ? x 2400 \\ 24 x 46 = ? x 2400 \\ ? = 46/100 \\ ? = 2350 \end{gathered}$$
