In the cash-flow diagram shown in the given figure A. Equal deposits of Rs. 3000 per year B. The rate of interest is 10% per year account C. The amount accumulated after the seventh deposit is to be computed D. All of these

The correct answer is D. All of these.

The cash-flow diagram shows that equal deposits of Rs. 3000 are made at the end of each year for 7 years. The interest rate is 10% per year. The amount accumulated after the seventh deposit is to be computed.

The formula for the future value of an annuity is $FV = A\left(\frac{1+r)^n-1}{r}\right)$, where $A$ is the amount of each deposit, $r$ is the interest rate, and $n$ is the number of years. In this case, $A = 3000$, $r = 0.1$, and $n = 7$. Substituting these values into the formula, we get $FV = 3000\left(\frac{1+0.1)^7-1}{0.1}\right) = 3000\left(\frac{1.1)^7-1}{0.1}\right) = 4346.44$. Therefore, the amount accumulated after the seventh deposit is Rs. 4346.44.
