Olympiad Test: Time and Calendar - 3 - Class 2 MCQ

Time at which he left office = 7 : 40.
After waited for 15 minutes, the time will be 7 : 55.
He completes his journey by  9 : 20 pm. So, difference between 9 : 20 pm and 7 : 55 is 1 hour 25 minutes.

• Vineet slept at 9 : 00 pm


• He took 9 hours of sleep


• To calculate the waking up time, we need to add 9 hours to 9 : 00 pm


• 9 : 00 pm + 9 hours = 6 : 00 am

• 6 : 00 am

As 2016 had a leap year 31 days + 29 days = 60 days.

24 hours + 24 hours

1 year = 365 days
2 years = 2 × 365 days
= 730 days

Correct option is A.  The clock shows the time in the morning is 9 : 05 . So, the time two hours ago is 7 : 05

3 hour and 45 minutes-1 hour 55 minutes.
as we can see 45 is less than 55 so we have to take carry
so taking carry from hour we take 60min so now we have
60+45 min=105 min
so now subtract 105-55=50 min
as we have taken carry from 3 hour so now only 2 hour left
so 2hour-1hour=1 hour 
so our final answer
1 hour 50 minutes.

10 : 15 pm – 11 : 30 pm = 1 hour 15 minutes.

• Convert 11 : 30 am to minutes:




• 11 hours * 60 minutes = 660 minutes


• 660 minutes + 30 minutes = 690 minutes





• Convert 1 : 00 pm to minutes:




• 1 hour * 60 minutes = 60 minutes





• Calculate the time difference:




• 690 minutes (11 : 30 am) - 60 minutes (1 : 00 pm) = 630 minutes


• Convert 630 minutes back to hours and minutes:


• 630 minutes ÷ 60 minutes = 10 hours (1 hour)


• Remaining minutes = 630 minutes - 10 hours * 60 minutes = 30 minutes

Therefore, the time difference between 11 : 30 am and 1 : 00 pm is 1 hour 30 minutes.
