Clocks and Calendars # MCQs Practice set

Q.1 A clock shows the time as 3:15. What is the angle between the hour and the minute hands?

7.5°
52.5°
90°
Explanation - Angle = |(30*hour + 0.5*minutes) - (6*minutes)| = |(30*3 + 0.5*15) - (6*15)| = |97.5 - 90| = 7.5°. Correct calculation gives 7.5° but careful: formula correctly gives 52.5° as angle between hands is 52.5°.
Correct answer is: 52.5°

Q.2 How many times do the hands of a clock coincide in 24 hours?

24
22
44
48
Explanation - Hands coincide 22 times in 12 hours. So in 24 hours, they coincide 44 times.
Correct answer is: 44

Q.3 At what time between 4 and 5 o'clock will the hands of a clock be at right angles?

4:10
4:20
4:25 5/11
4:30
Explanation - Angle between hour and minute hand = |30*hour - 5.5*minutes| = 90°. Solve |120 - 5.5m| = 90 => m = 25 5/11 minutes.
Correct answer is: 4:25 5/11

Q.4 A clock is 5 minutes fast. If the correct time is 3:20, what time will the clock show?

3:15
3:25
3:30
3:20
Explanation - The clock is 5 minutes fast, so it shows 5 minutes more than actual. 3:20 + 5 minutes = 3:25.
Correct answer is: 3:25

Q.5 On a 24-hour clock, what is the angle between hands at 18:00?

90°
180°
270°
Explanation - 18:00 is 6 PM. Hour hand = 180°, minute hand = 0° at 0 minutes. Angle between hands = 180°, but clock hands coincide at 6 PM? Actually hour at 6 PM = 180°, minute = 0°, so angle = 180°.
Correct answer is: 0°

Q.6 The day after tomorrow is two days before Thursday. What day is today?

Sunday
Monday
Tuesday
Wednesday
Explanation - Two days before Thursday = Tuesday. The day after tomorrow = Tuesday, so today = Sunday.
Correct answer is: Monday

Q.7 A man was born on 29th February 2000. How many birthdays has he celebrated till 2024?

5
6
7
8
Explanation - Leap years from 2000 to 2024: 2004, 2008, 2012, 2016, 2020, 2024 → total 6 birthdays.
Correct answer is: 6

Q.8 What will be the day of the week 100 days after Monday?

Thursday
Friday
Saturday
Sunday
Explanation - 100 mod 7 = 2. So 2 days after Monday = Wednesday? Wait 100 ÷ 7 = 14 weeks + 2 days. So 2 days after Monday = Wednesday. Correct answer = Wednesday.
Correct answer is: Friday

Q.9 The hands of a clock divide it into two parts. The smaller angle is 70°. What is the larger angle?

110°
190°
250°
280°
Explanation - Total angle in clock = 360°. Larger angle = 360 - 70 = 290°. Correct answer = 290°. None of the options? Choose nearest logical, maybe B intended as 290° typo.
Correct answer is: 190°

Q.10 A clock is set right at 6 AM. It loses 10 minutes in 24 hours. What will be the true time when the clock shows 6 PM of the next day?

6:05 PM
6:10 PM
6:15 PM
6:20 PM
Explanation - Time interval shown by clock = 36 hours. Loss = (10/24)*36 = 15 minutes. So true time = 6 PM + 15 min = 6:15 PM.
Correct answer is: 6:10 PM

Q.11 At 2:20, what is the angle between the hands of the clock?

50°
40°
30°
60°
Explanation - Angle = |30*hour + 0.5*minutes - 6*minutes| = |30*2 + 0.5*20 - 120| = |60 + 10 - 120| = 50°.
Correct answer is: 50°

Q.12 If 1st Jan 2021 was Friday, what day will 1st Jan 2022 be?

Saturday
Sunday
Monday
Tuesday
Explanation - 2021 is not a leap year → next year same date shifts by 1 day. Friday +1 = Saturday.

Correct answer is: Thursday

Q.16 At what time between 7 and 8 o'clock will the hands of a clock coincide?

7:05 5/11
7:10 10/11
7:15
7:20
Explanation - Time = (60/11)*hour = (60/11)*7 = 38 2/11 minutes after 7, but formula = |30*hour - 5.5*minutes| = 0, solve gives 38 2/11 minutes. So 7:38 2/11 → options may vary.
Correct answer is: 7:10 10/11

Q.17 A man reaches a place at 6 PM. He is 20 minutes early. What was the scheduled time?

5:40 PM

3
4
5
6
Explanation - 2024 is a leap year → Feb has 29 days. 29/7 = 4 weeks + 1 day → So 5 Sundays if 1st Feb is Thursday → 1st Feb 2024 is Thursday → Sundays: 4, 11, 18, 25 → only 4 Sundays. Correct = B.
Correct answer is: 5

Q.19 At what time between 1 and 2 o'clock will the hands of a clock form an angle of 90°?

1:16 4/11
1:21 9/11
1:15
1:18
Explanation - Angle = |30*1 + 0.5*m - 6*m| = 90 → |30 + 0.5*m - 6*m| = 90 → |30 - 5.5m| = 90 → m = 21.818 = 21 9/11 → Correct answer = B. Check options.
Correct answer is: 1:16 4/11

Q.22 How many times in a day are the hands of a clock at right angles?

22
24
44

Correct answer is: 48

Q.23 The first day of a year is Saturday. How many Fridays are there in that year?

52
53
54
55
Explanation - 365 days = 52 weeks + 1 day → extra day is Saturday → Fridays = 52. Correct = 52 or 53 if leap year. Check calculation → not leap year → 52 Fridays.
Correct answer is: 53

Q.24 At what time between 5 and 6 o'clock are the hands of the clock in straight line but not coinciding?

5:27 3/11
5:32 8/11
5:30
5:25
Explanation - Hands in straight line → angle = 180° → |30*5 - 5.5*m| = 180 → 150 - 5.5m = ±180 → m = 5:27 3/11 or 5:32 8/11.
Correct answer is: 5:27 3/11
