The correct answer is D. Rs 331.01.
Future value of annuity (FVA) is the total amount of money that will be accumulated at the end of a series of equal payments made at regular intervals over a period of time, assuming a fixed interest rate.
In this case, the deposited value is Rs 100 and the interest rate is 5% per year. The payments are made at the end of each year, so this is an ordinary annuity. The number of payments is 3.
The formula for FVA of an ordinary annuity is:
FVA = P(1 + r/n)^nt
where:
P = the present value of the annuity
r = the interest rate per period
n = the number of periods per year
t = the number of years
In this case, P = 100, r = 0.05, n = 1, and t = 3. Substituting these values into the formula, we get:
FVA = 100(1 + 0.05/1)^1*3 = 331.01
Therefore, the future value of the annuity is Rs 331.01.
Option A is incorrect because it is the present value of the annuity, not the future value.
Option B is incorrect because it is the future value of the annuity if the interest rate is 10% per year, not 5% per year.
Option C is incorrect because it is the future value of the annuity if the payments are made at the beginning of each year, not at the end of each year.
