Answer:
Option (D) 16.57%
Explanation:
Data provided in the question:
Realized gain
r₁ = 20%
r₂ = 20%
r₃ = 10%
Now,
Geometric average = [tex][(1+r_1)\times(1+r_2)\times...\times(1+r_n)]^{\frac{1}{n}}[/tex] - 1
here,
n = 3
therefore,
Geometric average = [tex][(1+0.20)\times(1+0.20)\times(1+0.10)]^{\frac{1}{3}}[/tex] - 1
or
Geometric average = [tex][1.584]^{\frac{1}{3}}[/tex] - 1
or
Geometric average = 1.1657 - 1
or
Geometric average = 0.1657
= 0.1657 × 100%
= 16.57%
