State True or False: `sum(q_1)/(q_0)xx100` is the Quantiy Index Number by Simple Aggregate Method.

Answer

To determine whether the statement "sum(q_1)/(q_0)xx100 is the Quantity Index Number by Simple Aggregate Method" is true or false, we can analyze the formula and its components step by step.

### Step-by-Step Solution:

1. **Understanding the Components**:
- In the context of index numbers, \( Q_0 \) typically represents the base period quantities, while \( Q_1 \) represents the current period quantities.

2. **Formula for Quantity Index Number**:
- The correct formula for the Quantity Index Number using the Simple Aggregate Method is given by:
\[ \text{Quantity Index Number} = \left( \frac{\sum Q_1}{\sum Q_0} \right) \times 100 \]
- This formula indicates that you should sum the current quantities (\( Q_1 \)) and divide by the sum of the base quantities (\( Q_0 \)), then multiply by 100 to express it as an index.

3. **Analyzing the Given Statement**:
- The statement provided is:
\[ \frac{\text{sum}(q_1)}{q_0} \times 100 \]
- Here, \( q_0 \) is not summed, which is incorrect. The base quantities should be summed as \( \sum Q_0 \).

4. **Conclusion**:
- Since the statement does not correctly represent the formula for the Quantity Index Number, we conclude that the statement is **False**.

### Final Answer:
The statement is **False**.
