The complete worked solution.
Every step explained - no skipped algebra.
The enquiry clerk said the bus left 10 minutes ago, and the next bus will leave at 10:30 a.m. Since buses leave every 30 minutes, the bus that left 10 minutes ago departed 20 minutes before 10:30, which is 10:10 a.m. Therefore, the clerk told this at 10:20 a.m. (10 minutes after the bus left).
Final Answer: Option A - 10:20 a.m.
