Important Formulae for CAT Clock and Calenders
For the purpose of CAT questions, a clock can be defined as a circle that is made of degrees, meaning that the angle in between the hands is more predominant than the time shown by the clock. On the other hand, following the same logic,the number of days in a month is much more important than the months themselves.
CAT Formulas for Clock
| Formulas for Clock | |
|---|---|
| 60-minute space = 360° = 1 hour | Straight Angle or Straight Line or 180° = 30-minute space apart |
| 1-minute space = 6° = 1 minute | Straight Angle = 11 times in 12 hours or 22 times in 24 hours (1 day) |
| 5-minute space = 6° x 5 = 30° = 5 minutes | Angle traced by hour hand in 12 hrs = 360° |
| Right Angle or Perpendicular = 15-minute spaces apart | Angle traced by minute hand in 60 min. = 360° |
| Right Angle or Perpendicular = 22 times in 12 hours or 44 times in 24 hours (1 day) | Speed of hour hand = 0.5 dpm (degree per minute) |
| Speed of minute hand = 6 dpm | Angle of the hour hand from vertical at N o’clock = 30N |
CAT Formulas for Calendar
| Formulas for Calendar |
|---|
| 1 ordinary year = 365 days = (52 weeks + 1 day.) |
| 1 ordinary year has 1 odd day. 1 leap year has 2 odd days. = (76 x 1 + 24 x 2) odd days = 124 odd days. |
