In a recurring deposit, the maturity value is given by:

1. $(P \times n) + I$

2. $P \times n \times I$

3. $\dfrac{P \times n \times I}{100}$

4. $\dfrac{(P \times n) + I}{100}$

₹ P is deposited for n number of months in a recurring deposit account which pays interest at the rate of r% per annum. The nature and time of interest calculated is :

1. compound interest for n number of months

2. simple interest for n number of months

3. compound interest for one month

4. simple interest for one month

In an R.D., the maturity value is the sum of the total amount deposited and the interest. If P is the amount deposited every month for n months and R is the rate of interest, then interest I is equal to:

1. $P \times \dfrac{n}{12} \times \dfrac{R}{100}$

2. $P \times \dfrac{n(n - 1)}{12} \times \dfrac{R}{100}$

3. $P \times \dfrac{n(n + 1)}{2 \times 12} \times \dfrac{R}{100}$

4. $P \times \dfrac{n}{2 \times 12} \times \dfrac{R}{100}$
