An аirline stоres ticket sаles in а sales table with cоlumns flight_number and amоunt. The finance team wants to know the total revenue per flight. Which SQL should they use? SELECT flight_number, SUM(amount) FROM sales GROUP BY flight_number SELECT SUM(amount) FROM sales SELECT flight_number, amount FROM sales ORDER BY flight_number SELECT flight_number, COUNT(amount) FROM sales GROUP BY flight_number Answer: SELECT flight_number, SUM(amount) FROM sales GROUP BY flight_number Explanation: SUM(amount) calculates total revenue per flight, grouped by flight_number. A plain SUM would only give overall revenue. Ordering by flight number doesn’t summarize. Using COUNT(amount) would return the number of sales, not revenue.
