Explanation by: Admin

angle traced by hour hand per minute = (1/2)°

∴ angled traced by hour hand in 8 h 30 min =[(8×60)+30x1/2]°

= [480+30×1/2]o°= 510 × (1/2)° = 255°

∴ Angle traced by minute hand per minute = 6°

∴ Angle traced by minute hand in 30 min = 30 × 6° = 180°

∴ required angle = (255° - 180°) = 75°
