Options

B. Rs. 1,13,520
C. Rs. 1,35,120
D. Rs. 1,15,320

Explanation

To solve the problem step by step, we will follow the information given in the question and perform the necessary calculations.

### Step 1: Determine Ms. Sujata's Monthly Salary
We know that Ms. Sujata invests 7% of her monthly salary in mutual funds, which amounts to Rs. 2170.

Let her monthly salary be \( X \).

The equation can be set up as:
\[ 0.07X = 2170 \]

To find \( X \), we can rearrange the equation:
\[ X = \frac{2170}{0.07} \]

Calculating this gives:
\[ X = 31000 \]

### Step 2: Calculate the Amount Invested in Recurring Deposits
Ms. Sujata invests 18% of her monthly salary in recurring deposits.

Calculating 18% of her monthly salary:
\[ \text{Amount in Recurring Deposits} = 0.18 \times 31000 = 5580 \]

### Step 3: Calculate the Amount Invested in NSC
Ms. Sujata invests 6% of her monthly salary in NSC.

Calculating 6% of her monthly salary:
\[ \text{Amount in NSC} = 0.06 \times 31000 = 1860 \]

### Step 4: Calculate Total Monthly Investment
Now, we need to find the total amount invested monthly by Ms. Sujata. We add the amounts from mutual funds, recurring deposits, and NSC:
\[ \text{Total Monthly Investment} = 2170 + 5580 + 1860 \]
Calculating this gives:
\[ \text{Total Monthly Investment} = 9610 \]

### Step 5: Calculate Total Annual Investment
To find the total annual amount invested, we multiply the total monthly investment by 12:
\[ \text{Total Annual Investment} = 9610 \times 12 \]
Calculating this gives:
\[ \text{Total Annual Investment} = 115320 \]

### Final Answer
The total annual amount invested by Ms. Sujata is Rs. 115320.
