The formula to calculate the amount obtained by investing a certain amount of money at a certain interest rate for a certain period of time is:

A = P(1 + r/n)^(nt)

Where:
A = the amount of money accumulated after n years, including interest.
P = principal amount (the initial amount of money)
r = annual interest rate (in decimal)
n = number of times that interest is compounded per year
t = time the money is invested for in years

In this case, the principal amount (P) is Rs.20,000, the annual interest rate (r) is 20% or 0.20 (in decimal), the number of times that interest is compounded per year (n) is 1 (since it's annually), and the time the money is invested for in years (t) is 2 years.

So, substituting these values into the formula, we get:

A = 20000(1 + 0.20/1)^(1*2)
A = 20000(1 + 0.20)^2
A = 20000(1.20)^2
A = 20000*1.44
A = Rs.28800

So, the amount obtained by investing Rs.20,000 at 20% per annum annually for 2 years is Rs.28800. Therefore, the correct option is Rs.28800.
