Explanation:

The Indian budget typically includes three key components for a given fiscal year:

1. Actual figures of the preceding years: These are the final figures from the financial statements of the previous fiscal year.

2. Revised estimates for the current year: These are the revised estimates of revenue and expenditure for the ongoing fiscal year. These estimates are adjusted during the year based on various factors such as economic conditions, revenue collections, and expenditure requirements.

3. Budget estimates for the upcoming year: These are the planned estimates for revenue and expenditure for the next fiscal year.

By presenting actual figures of the preceding years and revised estimates for the current year, the budget provides a comprehensive overview of the government's financial performance and its plans for the future.
