Answer

To solve the problem step by step, we will follow the calculations as described in the video transcript.

### Step 1: Determine Mrs. Sharma's Monthly Salary
We know that Mrs. Sharma invests 15% of her monthly salary in mutual funds, which amounts to Rs. 4428. We can set up the equation:

\[ 0.15 \times X = 4428 \]

Where \( X \) is Mrs. Sharma's monthly salary.

### Step 2: Solve for \( X \)
To find \( X \), we rearrange the equation:

\[ X = \frac{4428 \times 100}{15} \]

Calculating this gives:

\[ X = \frac{442800}{15} = 29520 \]

So, Mrs. Sharma's monthly salary is Rs. 29520.

### Step 3: Calculate the Total Percentage Invested
Now, we need to find out the total percentage of her salary that she invests. She invests:
- 15% in mutual funds
- 18% in pension plans
- 9% in insurance policies

Adding these percentages together:

\[ 15\% + 18\% + 9\% = 42\% \]

### Step 4: Calculate the Total Amount Invested
Now, we can calculate the total amount invested by Mrs. Sharma, which is 42% of her monthly salary:

\[ \text{Total Investment} = 0.42 \times 29520 \]

Calculating this gives:

\[ \text{Total Investment} = 12398.40 \]

### Final Answer
The total monthly amount invested by Mrs. Sharma is Rs. 12398.40.
