Each question is followed by two statements, I and II. Mark the answer:

1. If the question can be answered by using one of the statements alone, but cannot be answered using the other statement alone.

2. If the question can be answered by using either statement alone.

3. If the question can be answered by using both statements together, but cannot be answered using either statement alone.

4. If the question cannot be answered even by using both statements together.

What is the population of the village?

I. 7/11 of the village comprises of married people.

II.200 widows comprises 10% of the singles population.

- To find the population of the village, we analyze two statements.

- Statement I: 7/11 of the village comprises married people.

- This gives a proportion but does not give the actual number of people, so it's insufficient alone.

- Statement II: 200 widows comprise 10% of the singles population.

- This provides information about singles but not the total population or married people, so it's insufficient alone.

- Together: Using both statements, we know the married to total population ratio and can relate widow information to deduce singles.

- Calculating with both statements can lead to determining the total population.

- Thus, both statements together are needed to answer the question.
