Clock questions are a very important component of competitive exams including TOFEL, RRB, MBA, Bank PO, and CA. These questions usually involve solving time-related problems, such as calculating the difference in time between two events, figuring out when two clock hands will coincide, and figuring out the speed or rate at which a clock is running. These problems usually require the application of fundamental algebraic and arithmetic concepts.
Examiners frequently use clock problems to assess a candidate’s aptitude for using logic to reason with numbers, speed, and accuracy in computations, and application of mathematical ideas to practical settings. When evaluating a candidate’s general quantitative aptitude and problem-solving abilities, they might be a helpful tool.
Understanding Clock Questions
Clocks are an important component of logical thinking, which requires a thorough logical examination and a level of computation to answer the questions correctly. We provide you with a thorough understanding of clocks through this table:
| Topic | Description/Formula/Shortcut |
| Introduction of clock | 60-minute space = 360° = 1 hour1 minute = 6 degrees = 1 minute 6° x 5 = 30° = 5 minutes in a 5-minute space our hand speed = 0.5 DPM (degree per minute) Minute hand speed = 6 DPM At N o’clock, the angle of the hour hand from vertical is 30N or 30-minute intervals apart at a straight angle or straight line (180°) |
| Formulas for clock calculations | Hands coincide once per hour. Hands are 15-minute gaps apart at right angles Hands form a straight line when parallel or opposedHands are 30 minutes apart when facing each other Angle was drawn by minute hand in 60 minutes = 360° Angle drawn by hour hand in 12 hours = 360° The concept of the clock is fast or slow is based on deviation from the correct time The angle of the hour hand from vertical at ‘n’ o’clock is 30nHour hand covers 30° in one hour Minute hand covers 6° in one minute The angle between hour and minute hands when parallel or opposed is 0° The angle between hour and minute hands when facing each other is 180° |
| Important points and shortcuts | Hands coincide once per hour. Hands are 15-minute gaps apart at right angles Hands form a straight line when parallel or opposedHands are 30 minutes apart when facing each other Angle was drawn by minute hand in 60 minutes = 360° Angle drawn by hour hand in 12 hours = 360° The concept of the clock is fast or slow is based on deviation from the correct time The angle of the hour hand from vertical at ‘n’ o’clock is 30nHour hand covers 30° in one hour Minute hand covers 6° in one minute The angle between hour and minute hands when parallel or opposed is 0° The angle between hour and minute hands when facing each other is 180° |
| Concept of slow or fast clocks | Hands coincide once per hour. Hands are 15-minute gaps apart at right angles Hands form a straight line when parallel or opposedHands are 30 minutes apart when facing each other Angle was drawn by minute hand in 60 minutes = 360° Angle drawn by hour hand in 12 hours = 360° The concept of the clock is fast or slow is based on deviation from the correct time The angle of the hour hand from vertical at ‘n’ o’clock is 30nHour hand covers 30° in one hour Minute hand covers 6° in one minute The angle between hour and minute hands when parallel or opposed is 0° Angle between hour and minute hands when facing each other is 180° |
| Concept of angles | The hour hand moves at 0.5 degrees per minute (DPM) in 12 hours Minute hand moves at 6 degrees per minute (DPM) in 60 minutes The angle of the hour hand from vertical at ‘n’ o’clock is 30n degrees. |
