Find the future value of the following ordinary annuities.
a. FV of Rs 400 each 6 months for 5 years at a simple rate of 12 percent, compounded semiannually.
b. FV of Rs 200 each 3 months for 5 years at a simple rate of 12 percent, compounded quarterly.
c. The annuities described in parts (a) and (b) have the same amount of money paid into them during the 5-year period and both earn interest at the same simple rate, yet the annuity in part (b) earns more than the one in part (a) over the 5 years. Why does this occur?
