At 6:15, the hour hand and the minute hand of a clock from an angle of?

Angle traced by hour hand in 12 h = 360°
Angle traced by hour hand in 25/4 h = (360/12) x (25/4)° = 187.5°
Angle traced by minute hand in 60 min = 360°
Angle traced by it in 15 min = (360/60) x 15° = 90°
∴ Required angle = (187.5° - 90°) = 97.5°
