Clock questions test your ability to calculate angles, time intervals, and positions of clock hands. These questions are common in aptitude and reasoning examinations.
Question 1
At 3:00, what is the angle between the hour hand and the minute hand?
A) 45°
B) 60°
C) 90°
D) 120°

A) 30°
B) 45°
C) 60°
D) 90°
Answer
C) 60°
Explanation

Therefore:
360 ÷ 60 = 6° per minute
In 10 minutes:
10 × 6 = 60°
Question 4
How many degrees does the hour hand move in 1 hour?
A) 20°
B) 25°
C) 30°
D) 35°
Answer
C) 30°
Explanation

A) 0°
B) 30°
C) 60°
D) 90°
Answer
A) 0°
Explanation
Both hands overlap at 12.
Therefore the angle is 0°.
Key Learning
Important Facts:
Minute hand moves 6° per minute
Hour hand moves 30° per hour
Full circle = 360°
These facts help solve most basic clock problems.
Practice Tip
Memorize:
3:00 → 90°
6:00 → 180°
9:00 → 90°
12:00 → 0°
These are frequently used reference points.
