Answer

To find Amla's annual income based on the information given, we can follow these steps:

### Step 1: Determine Meera's Monthly Income
Meera's annual income is given as Rs. 4,29,600. To find her monthly income, we divide her annual income by 12 (the number of months in a year).

\[ \text{Meera's Monthly Income} = \frac{\text{Meera's Annual Income}}{12} = \frac{4,29,600}{12} \]

### Step 2: Calculate Meera's Monthly Income
Now we perform the division:

\[ \text{Meera's Monthly Income} = 4,29,600 \div 12 = 35,800 \]

### Step 3: Calculate Amla's Monthly Income
According to the problem, Amla's monthly income is four-fifths of Meera's monthly income. We can calculate Amla's monthly income as follows:

\[ \text{Amla's Monthly Income} = \frac{4}{5} \times \text{Meera's Monthly Income} = \frac{4}{5} \times 35,800 \]

### Step 4: Perform the Calculation for Amla's Monthly Income
Now we perform the multiplication:

\[ \text{Amla's Monthly Income} = \frac{4 \times 35,800}{5} = \frac{143,200}{5} = 28,640 \]

### Step 5: Calculate Amla's Annual Income
To find Amla's annual income, we multiply her monthly income by 12:

\[ \text{Amla's Annual Income} = \text{Amla's Monthly Income} \times 12 = 28,640 \times 12 \]

### Step 6: Perform the Calculation for Amla's Annual Income
Now we perform the multiplication:

\[ \text{Amla's Annual Income} = 28,640 \times 12 = 3,43,680 \]

### Final Answer
Thus, Amla's annual income is Rs. 3,43,680.
