    Find the angle between the minute hand and hour hand at

    9:30 am?
    A 105° Correct Answer Incorrect Answer
    B 110° Correct Answer Incorrect Answer
    C 90° Correct Answer Incorrect Answer
    D 120° Correct Answer Incorrect Answer

    Solution

    The logic followed here is as follows, Hour hand makes an angle of 30° in one hour and an angle of 0.5° in one minute.
    Similarly, minute hand makes an angle of 6° in one minute.
    So, angle made by hour hand at 9:30 am= (9 × 30 + 0.5 × 30) = 270 + 15 = 285°
    Similarly, angle made by minute hand at 9:30 am= 30 × 6 = 180°
    So, the angle between minute and hour hand= 285 – 180 = 105°
