How many buses are required to carry all passengers landing at BLR airport?
Treat this as a practical data pipeline and estimation task. Define the passenger and arrival data required, explain assumptions such as bus capacity and time window, calculate the result with a reproducible batch process, and describe validation, reruns, and monitoring. State how you would handle missing, duplicated, delayed, or conflicting arrival records.
