A good sampling strategy for this survey would be to use stratified random sampling. This would involve dividing the village into different strata or groups based on factors such as class and caste, and then selecting a certain number of households from each stratum to participate in the survey. For example, the village could be divided into strata based on class (upper, middle, lower) and caste (scheduled castes, scheduled tribes, other backward classes, general), and then 100 households could be randomly selected from each stratum to participate in the survey.

As for the 10 most important questions to ask in the survey, some possible options could include:

1. What is your current marital status?
2. Are you currently employed outside of the home? If so, in what type of work?
3. Have you received any formal education? If so, what is the highest level of education you have completed?
4. Do you have access to healthcare services in your community?
5. Do you feel safe in your home and community?
6. Do you have any decision-making power within your household?
7. Do you have access to financial resources and/or credit?
8. Have you experienced any form of gender-based violence or discrimination?
9. Are you involved in any community organizations or activities?
10. Do you have any unmet needs or challenges that you would like to see addressed in your community?

These questions are designed to provide a broad overview of the situation of women in rural India, including their socioeconomic status, access to education and healthcare, safety and security, decision-making power, and involvement in their communities. By collecting data on these and other factors, it will be possible to identify any disparities or challenges facing women in rural India and develop appropriate interventions to address them.
