Clock questions are a common part of many competitive exams. These questions test your ability to understand the movement of the hour and minute hands of a clock and calculate angles and positions.
Let’s dive into ten clock questions similar to those you might encounter during CLAT.
CLOCK QUESTIONS FOR CLAT QUANTITATIVE APTITUDE
Question 1
The angle swept by the hour hand of a clock from 3 a.m. to 3 p.m.
(a) 360
(b) 180
(c) 270
(d) 90
Answer 1: (a) 360
Explanation: The hour hand of a clock completes a full 360-degree rotation in 12 hours. Therefore, from 3 a.m. to 3 p.m., it sweeps an angle of 360 degrees.
Question 2
The angle swept by the minute hand of a clock from 6 a.m. to 6:45 a.m.
(a) 180
(b) 210
(c) 270
(d) None of these
Answer 2: (b) 210
Explanation: The minute hand of a clock completes a full 360-degree rotation in 60 minutes. From 6 a.m. to 6:45 a.m., it sweeps an angle of (360/60) * 45 = 210 degrees.
Question 3
The angular value of a minute is
(a) 30 degrees
(b) 10 degrees
(c) 6 degrees
(d) Cannot be calculated
Answer 3: (a) 30 degrees
Explanation: Each minute on a clock represents 360 degrees divided by 60 minutes, which equals 6 degrees per minute. Therefore, the angular value of a minute is 6 degrees.
Question 4
A clock started at 3 p.m., and by 15 minutes past 6, the hour hand had turned through what degrees?
(a) 195/2
(b) 173/2
(c) 153/3
(d) 198/5
Answer 4: (a) 195/2
Explanation: The hour hand moves at a rate of 360 degrees in 12 hours, which is 30 degrees per hour. From 3 p.m. to 6:15 p.m., it has moved 3 hours and 15 minutes, which is (3 + 15/60) hours. Therefore, the angle covered is (30 * (3 + 15/60)) degrees, which simplifies to (30 * (195/4)) degrees or (195/2) degrees.
Question 5
If a clock starts at noon, then by how many degrees has the hour hand rotated when it is 7 p.m.?
(a) 230
(b) 210
(c) 180
(d) 190
Answer 5: (b) 210
Explanation: From 12 noon to 7 pm, the hour hand has moved 7 hours. Since it moves at a rate of 30 degrees per hour, the angle covered is 7 * 30 = 210 degrees.
Question 6
What is the angle between the minute hand and the hour hand when the time is 10:15 p.m.?
(a) 190
(b) 210
(c) 220
(d) 230
Answer 6: (b) 210
Explanation: To find the angle between the minute hand and the hour hand at 10:15 p.m., we can use the formula: (30*hour – (11/2) minutes)|. Substituting the values: |(3010 – (11/2)*15)| = |(300 – 82.5)| = 217.5 degrees, which is approximately 210 degrees.
Question 7
At what angle are the hour hand and the minute hand when it is 2:30 p.m.?
(a) 100
(b) 105
(c) 150
(d) 170
Answer 7: (b) 105
Explanation: At 2:30 p.m., the hour hand is on 2, and the minute hand is on 6. To find the angle between them, we can use the formula: |(30*hour – (11/2) minutes)|. Substituting the values: |(302 – (11/2)*30)| = |(60 – 165)| = 105 degrees
Question 8
How many times in 3 days are the hands of a clock in a straight line but in the same direction?
(a) 6
(b) 8
(c) 10
(d) 12
Answer 8: (a) 6
Explanation: In 3 days, the hour and minute hands of the clock will be in a straight line but moving in the same direction 6 times.
Question 9
If a clock starts at 5:00 p.m., then by how many degrees has the hour hand of the clock rotated at 11:00 p.m.?
(a) 210
(b) 180
(c) 90
(d) 360
Answer 9: (b) 180
Explanation: From 5:00 pm to 11:00 pm, the hour hand has moved 6 hours, and since it moves at a rate of 30 degrees per hour, it has rotated 6 * 30 = 180 degrees.
Question 10
The angle between the hour hand and minute hand at 7:20 p.m. is
(a) 120
(b) 180
(c) 210
(d) 90
Answer 10: (b) 180
Explanation: To find the angle between the hour hand and minute hand at 7:20 p.m., we can use the formula: |(30*hour – (11/2) minutes)|. Substituting the values: |(307 – (11/2)*20)| = |(210 – 110)| = 180 degrees.
