Clock Questions

Clock Problems

The different types of clock questions that can be asked in the CAT 2019 exam are:

• Angle related clock problems
• Faulty Clock questions
• Time gain or Time Loss clock questions

Clock Problem Concepts:

• The dial of the clock is circular in shape and was divided into 60 equal minute spaces
• 60-minute spaces trace an angle of 360°. Therefore, 1minute space traverses an angle of 6°
• In 1 hour, Minute hand traverses 60-minute space or 360° , Hour hand traverses 5-minute space or 30°
• The hands of the clock are perpendicular in 15-minute spaces apart
• The hands of the clock are in straight line and opposite to each other in 30-minute spaces apart.
• The hands of the clock are in straight line when they coincide or opposite to each other.
• The hands of the clock are perpendicular to each other for 22 times in 12 hours and for 44 times in a day.
• The hands of the clock are opposite to each other for 11 times in 12 hours and 22 times in a day.
• The minute hand gain 55 minutes over hour hand per hour.

The angle Φ between the hour hand and minute hand of the clock at any given point of time can be calculated using the given formula
