Price Index Number by Simple Aggregate Method is given by ................ .

Answer

To find the Price Index Number by the Simple Aggregate Method, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Prices**:
- Let \( P_0 \) be the price of commodities in the base year.
- Let \( P_1 \) be the price of commodities in the current year.

2. **Calculate the Total Current Prices**:
- Sum up all the current prices of the commodities:
\[ \text{Total Current Prices} = \sum P_1 \]

3. **Calculate the Total Base Prices**:
- Sum up all the base prices of the commodities:
\[ \text{Total Base Prices} = \sum P_0 \]

4. **Apply the Formula for Price Index Number**:
- The Price Index Number (PIN) by the Simple Aggregate Method is calculated using the formula:
\[ \text{Price Index Number} = \left( \frac{\sum P_1}{\sum P_0} \right) \times 100 \]

5. **Interpret the Result**:
- The resulting value gives you the Price Index Number, which indicates the relative change in prices from the base year to the current year.

### Final Formula:
\[ \text{Price Index Number} = \left( \frac{\sum P_1}{\sum P_0} \right) \times 100 \]
