The angle between the minute hand and the hour hand of a clock at “half past 33” is equal to

Options

  1. A90o{90}^{o}
  2. B80o{80}^{o}
  3. C75o{75}^{o}
  4. D60o{60}^{o}

Correct answer

C. 75o{75}^{o}

Step-by-step solution

The angle subtended by two consecutive marks at the center =30o= {30}^{o}
Hence, at “half past 33 ” the angle is 30o+30o+15o=75o{30}^{o} + {30}^{o} + {15}^{o} = {75}^{o}
