Clock Reasoning Formula

The formula for Clock Angle:

Minute Hand Concept

    • In 60 Minutes – Rotate 360°
    • In 1 Minute – 360060 = Rotate 6°

Hour Hand Concept

    • In 12 Hours – Rotate 360°
    • in 1 Hour –  360012 = Rotate 30°
    • So, In 1 Minute = 30060������ = (½)° = Rotate 0.5°For example, How much angle does the hand make, If it turns from 2 pm to 4 pm?
      => Total Time 2 Hours = 120 Minute
      hour hand make an 0.5° in 1 Minute
      So, In 2 hours,
      120 Minute  x 0.5° = 60° (Ans)

Angle Formula

    • H x 30 = F°
    • M x112= y°
    • See question number 16 for example

Types of Clock Reasoning 

1. Angle Based Clock 

2. Reflection of Clock

3. Defective Clock
