CBSE Class 4 Maths Tick Tick Tick Worksheet Set 01

Ques.1 Match the following:-
जोडे मिलाओ:-

I. 3 hours / 3 घंटे                        a) 2 days / 2 दिन
II. 48 hours / 48 घंटे                   b) 180 minutes / 180 मिनट
III. 1/3 hour / 1/3 घंटा                 c) 4 hour / 4 घंटे
IV. 240 minutes / 240 मिनट       d) 20 minutes / 20 मिनट

Question 1. Match the given time conversions correctly.
Answer:
(i) -> b) (3 hours = \(3 \times 60\) minutes = 180 minutes)
(ii) -> a) (48 hours = \(48 \div 24\) days = 2 days)
(iii) -> d) (\(\frac{1}{3}\) hour = \(\frac{1}{3} \times 60\) minutes = 20 minutes)
(iv) -> c) (240 minutes = \(240 \div 60\) hours = 4 hours)
In simple words: Match each time duration with its equivalent value in a different unit by multiplying or dividing by conversion factors like 60 or 24.

Exam Tip: Remember that 1 hour = 60 minutes, 1 day = 24 hours, and 1 hour = 3600 seconds to quickly solve conversion questions.

Ques.2 Fill in the blanks:-
रिक्त स्थान भरो

Question 2. Convert between 12-hour clock time and 24-hour clock time for the given entries.
Answer:
(i) 20:00 hours / 20:00 घंटे
(ii) 09:30 am / 09:30 सुबह
(iii) 03:20 hours / 03:20 घंटे
(iv) 09:40 pm / 09:40 pm
In simple words: To convert PM times (from 1:00 pm onwards) to 24-hour format, add 12 to the hour. AM times remain the same in both systems.

Exam Tip: In 24-hour clock format, times from midnight to noon are written as 4 digits without am/pm, and afternoon/evening times have 12 added to the hour.

Ques.3 Complete the following:-
निम्न को पूरा कीजिए |

Question 3. Calculate the time 8 hours after the given times.
Answer:
(i) 8 am + 8 hours = 4:00 pm / 4 बजे
(ii) 4 pm + 8 hours = 12 midnight / 12 मध्यरात्रि
(iii) 9 am + 8 hours = 5:00 pm / 5 बजे
In simple words: Add 8 hours to the starting time, keeping track of transitions from morning (am) to evening (pm).

Exam Tip: Count hours carefully past 12:00 noon to switch correctly from am to pm.

Ques.4 Write the time in figures:-
समय को अंको में लिखो :-
1. 7 minutes to 10                  10 बजने मे सात मिनट

In simple words: Translate word descriptions of time into standard digital hour and minute figures.

Exam Tip: "Minutes to" means you subtract those minutes from the next upcoming hour (e.g., 7 minutes to 10 is 60 - 7 = 53 minutes past 9).

Ques.5 Make a clock and show the time:-
घड़ी बनाकर समय दर्शाओं |
1. 10 minutes to 8. / 8 बजने मे १० मिनट
2. 25 minutes past 12. / 12 बजकर २५ मिनट
Answer:
1. Draw a clock face with the short hour hand pointing just before 8 and the long minute hand pointing at 10 (representing 7:50).
2. Draw a clock face with the short hour hand pointing past 12 and the long minute hand pointing at 5 (representing 12:25).
In simple words: Sketch a clock and position the hour and minute hands accurately for the given times.

Exam Tip: The short hand shows the hour and the long hand shows the minutes (each number on the clock represents 5 minutes).

Ques.6 Match the following:-
जोडे मिलाओ:-

i) 2 years 7 months / 2 साल ७ महीने                  a) 4 years 4 days / 4 वर्ष 4 दिन

Question 6. Match the given time periods correctly.
Answer:
(i) -> c) (2 years 7 months = \(2 \times 12 + 7 = 24 + 7 = 31\) months)
(ii) -> a) (48 months = \(48 \div 12\) years = 4 years; note: matching corresponds to available options index key)
(iii) -> d) (4 weeks = \(4 \times 7\) days = 28 days)
(iv) -> b) (35 days = \(35 \div 7\) weeks = 5 weeks)
In simple words: Match each duration by converting units (1 year = 12 months, 1 week = 7 days).

Ques.7 The annual examination in a school started on 1st march 2012 and ended on 22nd march 2012. How long did the examination continue?
एक विद्यालय में वार्षिक परीक्षा १ मार्च २०१२ को शुरू हुई और २२ मार्च २०१२ को समाप्त हुई | वार्षिक परीक्षा कितने दिन तक चली ?
Answer:
Start date = March 1, 2012
End date = March 22, 2012
Total duration = End date - Start date + 1
\(22 - 1 + 1 = 22\) days / २२ दिन
In simple words: Count all days from March 1 to March 22 inclusive, giving 22 days.

Exam Tip: When finding the total number of days between two dates inclusive, subtract the start date from the end date and add 1.

23 मार्च २०१२ को क्या दिन होगा _______________.
Answer:
1. Tuesday / मंगलवार
2. Friday / शुक्रवार

Exam Tip: Add or subtract multiples of 7 days to find the day of the week for any given date.

Ques.11 Which month it will be 240 days after 10/01/2012?
१०/०१/२०१२ के २४० दिन बाद कौन सा महीना होगा ?
Answer:
Starting date: January 10, 2012 (Year 2012 is a leap year, February has 29 days).
Days remaining in January: \(31 - 10 = 21\) days
February 2012: 29 days
March 2012: 31 days
April 2012: 30 days
May 2012: 31 days
June 2012: 30 days
July 2012: 31 days
August 2012: 31 days
Total days accounted for up to end of August = \(21 + 29 + 31 + 30 + 31 + 30 + 31 + 31 = 234\) days.
Remaining days to reach 240 = \(240 - 234 = 6\) days into September.
Therefore, the month will be September / सितम्बर.
In simple words: Count forward 240 days month by month from January 10, accounting for the leap year, to land in September.

Exam Tip: Always check if the given year is a leap year (divisible by 4) when February is included in day calculations.

Ques.12 A hockey match ended at 03:20 pm. If the match lasted for 2 hours 30 minutes. When did it start?
हाँकी का मैच ३:२० एम पर खत्म हुआ | यदि मैच २ घंटे ३० मिनट चला तो मैच सुरु होने का समय लिखो |
Answer:
End time = 03:20 pm
Duration = 2 hours 30 minutes
Subtract duration from end time:
Minutes: \(20 - 30\). Since 20 is smaller than 30, borrow 1 hour (60 minutes) from 3 hours.
New end time representation = 2 hours 80 minutes pm
Subtracting duration:
Hours: \(2 - 2 = 0\)
Minutes: \(80 - 30 = 50\) minutes
Start time = 12:50 pm
In simple words: Subtract 2 hours and 30 minutes from 3:20 pm by borrowing 60 minutes, which gives 12:50 pm.

Exam Tip: When subtracting time where minutes are insufficient, borrow 60 minutes from the hour column.

Ques.13 It takes Rohan 45 minutes to reach the school. If he reaches school at 08.10 am. What time did he set out?
रोहन को विद्यालय पहुँचने में ४५ मिनट लगते हैं यदि वह विद्यालय ८:१० अपर्हान पर पहुँचता है तो वह कितने बजे घर से चला होगा ?
Answer:
Arrival time = 08:10 am
Time taken = 45 minutes
Subtracting 45 minutes from 08:10 am:
Borrow 1 hour (60 minutes) from 8 hours: \(8:10\) becomes \(7:70\)
\(7:70 - 0:45 = 7:25\)
Start time = 07:25 am
In simple words: Count backward 45 minutes from 8:10 am to find he left at 7:25 am.

Exam Tip: Subtracting minutes across the hour boundary requires borrowing 60 minutes from the hours.

Ques.14 Write the time in words:-
समय को शब्दों में लिखो:-
1. 08:15 ______________
2. 09:40 ______________
3. 07:45 ______________

Ques.15 Add:-
जोड़ो
1. 36 minutes to 48 minutes_______________.
३६ मिनट और ४८ मिनट _______________.
2. 1 hour 15 minutes and 2 hour 50 minutes_____________.
१ घंटा १५ मिनट और २ घंटे ५० मिनट _______________.
Answer:
1. \(36 + 48 = 84\) minutes = 1 hour 24 minutes / 1 घंटा २४ मिनट
2. Adding hours and minutes separately:
Hours: \(1 + 2 = 3\) hours
Minutes: \(15 + 50 = 65\) minutes
Since 65 minutes = 1 hour 5 minutes, add 1 hour to total hours:
Total = \(3 \text{ hours} + 1 \text{ hour } 5 \text{ minutes} = 4\) hours 05 minutes / चार घंटे ०५ मिनट
In simple words: Add the minutes and hours separately, and convert every 60 minutes into 1 extra hour.
