Mr. Mirza's monthly income is रु 7,200 . He spends. रु 1,800 on rent रु 2,700 on food, रु 900 on education of his children रु 12,00 on other things and saves the rest. Draw a pie- chart to represent it.

Answer

To draw a pie chart representing Mr. Mirza's monthly income and expenses, we will follow these steps:

### Step 1: Identify Total Monthly Income
Mr. Mirza's total monthly income is given as:
- **Total Income (I)** = रु 7,200

### Step 2: Identify Monthly Expenses
The monthly expenses are:
- Rent (R) = रु 1,800
- Food (F) = रु 2,700
- Education (E) = रु 900
- Other Expenses (O) = रु 1,200

### Step 3: Calculate Total Expenses
To find the total expenses, we add up all the expenses:
- Total Expenses = Rent + Food + Education + Other Expenses
- Total Expenses = 1,800 + 2,700 + 900 + 1,200
- Total Expenses = 6,600

### Step 4: Calculate Savings
To find the savings, we subtract the total expenses from the total income:
- Savings (S) = Total Income - Total Expenses
- Savings = 7,200 - 6,600
- Savings = 600

### Step 5: Calculate the Angles for the Pie Chart
The total angle in a pie chart is 360 degrees. We need to find the angle for each category based on their proportion of the total income.

1. **Angle for Rent**:
- Angle for Rent = (Rent / Total Income) × 360
- Angle for Rent = (1,800 / 7,200) × 360 = 90 degrees

2. **Angle for Food**:
- Angle for Food = (Food / Total Income) × 360
- Angle for Food = (2,700 / 7,200) × 360 = 135 degrees

3. **Angle for Education**:
- Angle for Education = (Education / Total Income) × 360
- Angle for Education = (900 / 7,200) × 360 = 45 degrees

4. **Angle for Other Expenses**:
- Angle for Other Expenses = (Other Expenses / Total Income) × 360
- Angle for Other Expenses = (1,200 / 7,200) × 360 = 60 degrees

5. **Angle for Savings**:
- Angle for Savings = (Savings / Total Income) × 360
- Angle for Savings = (600 / 7,200) × 360 = 30 degrees

### Step 6: Draw the Pie Chart
Now that we have all the angles, we can draw the pie chart:
- Rent: 90 degrees
- Food: 135 degrees
- Education: 45 degrees
- Other Expenses: 60 degrees
- Savings: 30 degrees

### Summary of Angles:
- Rent: 90°
- Food: 135°
- Education: 45°
- Other Expenses: 60°
- Savings: 30°
