154) Find the angle between the hands of clock at 8 : 20.
Correct Answer - Option
(A)
Explanation :
Angle traced by hour hand per minute = (1/2)o
∴Angle traced by hour hand in 8h 20 min = ( 8 x 60 + 20) × 1/2
= 250°
Again, angle traced by minute hand per minute = 6°
∴ again traced by minute hand in 20 min = 20 × 6°
= 120°
Therefore required angle = (250° - 120°) = 130°
∴Angle traced by hour hand in 8h 20 min = ( 8 x 60 + 20) × 1/2
= 250°
Again, angle traced by minute hand per minute = 6°
∴ again traced by minute hand in 20 min = 20 × 6°
= 120°
Therefore required angle = (250° - 120°) = 130°
T
155) What will be the angle between the hands of clock at 7 : 10?
Correct Answer - Option
(D)
Explanation :
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°
∴ 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°
T
156) Find the angle traced by hour hand of a correct clock between 8 O' clock and 2O' clock.
Correct Answer - Option
(A)
Explanation :
Angle traced by hour hand per minute = (1/2)°
∴ Angle traced by hour hand in 1 h = 1°/2 × 60 = 30°
Time period between 8 O' clock to 2 O' clock = 6h
∴ angle traced by hour hand in 6h = 30° × 6 = 180°
∴ Angle traced by hour hand in 1 h = 1°/2 × 60 = 30°
Time period between 8 O' clock to 2 O' clock = 6h
∴ angle traced by hour hand in 6h = 30° × 6 = 180°

160) A clock gains 5 minutes in one hour. Therefore, the angle traversed by the minute hand in 1 hour is
Correct Answer - Option
(B)
Explanation :
Clearly, the minute hand traverses 65 minutes in 1 hour.
∴ Required angle = (360/60×65)°=360°
∴ Required angle = (360/60×65)°=360°
