CSEET clock MCQs with explanations

Here are 15 multiple-choice questions (MCQs) on Clocks for the CSEET Logical Reasoning section, with answers and explanations 

1. How many times in a day are the hands of a clock in a straight line (either same direction or opposite)?

A. 22B. 24C. 44D. 48

Answer: C. 44Explanation:The hands are in the same straight line (overlapping or opposite) 22 times in 12 hours. Hence, in 24 hours, it happens 44 times.

2. How many times in a day are the hands of a clock at right angles?

A. 22B. 44C. 48D. 24

Answer: B. 44Explanation:In 12 hours, the hands are at right angles 22 times.So, in 24 hours → 22 × 2 = 44 times Hence, correct answer is 44 

Corrected Answer: B. 44

3. How many times do the hands of a clock coincide in a day?

A. 11B. 22C. 24D. 12

Answer: B. 22Explanation:Hands coincide 11 times in 12 hours, so 22 times in 24 hours.

4. How much angle do the hands of a clock make when it is 3:15?

A. 45°B. 7.5°C. 42.5°D. 37.5°

Answer: B. 7.5°Explanation:At 3:15,

Minute hand = 15 × 6 = 90°

Hour hand = 3 × 30 + 15 × 0.5 = 90 + 7.5 = 97.5°→ Angle = |97.5 – 90| = 7.5° (smaller angle),But for 3:15, the larger angle = 360 – 7.5 = 352.5°Usually, we take smaller one → 7.5° 

5. When will the hands of a clock be together between 2 and 3 o’clock?

A. 2:10B. 2:11C. 2:10:55D. 2:12

Answer: C. 2:10:55Explanation:Formula:

Minutes=60/11H

For 2 o’clock, H = 2 → (60/11) × 2 = 120/11 = 10 10/11 ≈ 10 min 55 sec.→ 2:10:55

6. At what time between 4 and 5 will the hands be at right angles?

A. 4:10 10/11B. 4:21 9/11C. Both A and BD. None

Answer: C. Both A and BExplanation:Formula:

Minutes=60/11H±30/11

For H = 4,→ 4:10 10/11 and 4:21 9/11

7. How many degrees does the hour hand move in 1 hour?

A. 30°B. 15°C. 6°D. 60°

Answer: A. 30°Explanation:Clock is 360° and divided into 12 hours → 360/12 = 30° per hour.

8. How many degrees does the minute hand move in one minute?

A. 12°B. 6°C. 60°D. 30°

Answer: B. 6°Explanation:Minute hand completes 360° in 60 minutes → 360/60 = 6° per minute.

9. The angle between the hands at 5:30 is:

A. 75°B. 90°C. 15°D. 120°

Answer: C. 15°Explanation:

Hour hand = 5×30 + 30×0.5 = 150 + 15 = 165°

Minute hand = 30×6 = 180°→ Difference = |180–165| = 15° (smaller angle)Right answer (based on direction) is 15°

Correct smaller angle = 15°

(If question means “larger angle,” answer would be 345°)

10. What is the angle between the hands at 7:20?

A. 100°B. 110°C. 120°D. 130°

Answer: B. 110°Explanation:

Hour hand = 7×30 + 20×0.5 = 210 + 10 = 220°

Minute hand = 20×6 = 120°→ Difference = 220–120 = 100°

Correct answer: A. 100°

11. At what time between 9 and 10 will the hands be together?

A. 9:45B. 9:49 1/11C. 9:50D. 9:55

Answer: B. 9:49 1/11Explanation:

Minutes=60/11H=60/11×9=491/11

→ 9:49 1/11

12. The hands of a clock are opposite each other at:

A. 5:40B. 6:00C. 7:05D. 6:30

Answer: A. 5:40Explanation:Formula for opposite:

Minutes=60/11H+30/11​

For H = 5 → (60×5 + 30)/11 = 330/11 = 30 min.Wait — correction: For 5 o’clock, opposite is 5:40.

13. If a clock is 5 minutes slow at 8 a.m. and 5 minutes fast at 8 p.m., when was it correct?

A. 2 p.m.B. 1 p.m.C. 12 noonD. 11 a.m.

Answer: C. 12 noonExplanation:Total gain = 10 minutes in 12 hours → 1 minute gained every 72 minutes.To gain 5 minutes (to become correct) → 5×72 = 360 min = 6 hours after 8 a.m. → 2 p.m.

Corrected Answer: A. 2 p.m.

14. The hands of a clock are together for the first time after 12 o’clock at:

A. 12:05B. 12:06C. 12:05:27D. 12:06:05

Answer: C. 12:05:27Explanation:Formula: Minutes = (60/11) × HFor H = 0 → 0, next overlap → (60/11) × 1 = 5 5/11 = 5 min 27 sec

15. A clock gains 2 minutes every hour. If it is set correctly at 12 noon, what time will it show at 6 p.m. (real time)?

A. 6:12 p.m.B. 6:10 p.m.C. 5:48 p.m.D. 6:02 p.m.

Answer: A. 6:12 p.m.Explanation:Gain = 2 min per hour × 6 hours = 12 minutes.So, at real 6 p.m., clock shows 6:12 p.m.
