The geometric mean of a set of observations is computed as 10 . The geometric mean obtained when each observation x_i is replaced by 3 x_i^4 is

Options

  1. A810
  2. B900
  3. C30000
  4. D81000

Correct answer

C. 30000

Step-by-step solution

Geometric mean =10 when, each observation is replaced by 3 x_i^4 Now G.M. =3 .(10)^4=30000
