The absolute refractive indices of glass and water are 4/3 and 3/2, respectively. If the speed of light in glass is 2×108 m/s, calculate the speed of light in vaccum and water.

You have written the wrong question as refractive index of glass is 3/2 and water 4/3.
ng = 3/2 and nw = 4/3.
Absolute Refractive Index of a medium = Speed of light in vacuum/Speed of light in the medium
Speed of light in glass = 2 x 108 m/s
Speed of Light in Vacuum = (3/2) x 2 x 108 m/s = 3 x 108 m/s
Speed of light in water = (3 x 108m/s)/(4/3)
= 2.25 x 108 m/s
