Question 48. The angle between the hour hand and minute hand when the time is 6 hours 45 minutes, is:

  1. a. 60°
  2. b. 62.5°
  3. c. 65°
  4. d. 67.5°

Solution:

  1. Answer: (d)

    Angle moved by hour hand in every minutes = 360/12 × 60 = 0.5°

    Angle moved by hour hand in every minutes = 360/60 = 6°

    Starting from 6 o'clock, in 45 minute hour hand will travel 45 x 0.5° = 22.5°

    Starting from 6 o'clock, in 45 minute hand will travel 45 x 6° = 270°

    Angle between them 270° - 22.5° = 247.5°

    But they already had angle of 180° between them at 6 o'clock

    So, the angle between them now is 247.5° - 180° = 67.5°

Question 51. The number of numbers from 1 to 200 which are divisible by 10 but not divisible by 30, is :

  1. a. 13
  2. b. 15
  3. c. 14
  4. d. 20

Solution:
