In a recurring deposit (R.D.):

1. a person gets the same interest every month

2. a person gets the same maturity amount every year

3. a person deposits the same amount every month

4. the government deposits an amount equal to the interest every year.

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

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