Test: Time - 1 - Class 4 MCQ

One hour = 60 minutes
∴ In 2 hours = 2 x 60 = 120

2 hours 30 minutes = 120 + 30 minutes
= 150 minutes

1 hour = 60 minutes

so 1 min = 1/60 hr

240 min = 240 x 1/60 = 4 hours

12 hrs is the pm clock time corresponding to p.m. in the 24-hour clock.

7 hours 25 mins= (7 x 60) + 25

⇒ 420 + 25

⇒ 445 minutes

3 hours 45 mins = (3 x 60) + 45

⇒ 180 + 45

⇒ 225

Difference = 445 - 225 minutes

⇒ 220 minutes

⇒ 220/60 hours

⇒ 3 hours 40 minutes (approx)

Difference between 2019 & 1998 is 21

Leena's age in 2019 is 53

So, her age in 1998 would be

⇒ 53 - 21 = 32 years

We know, 

One quarter minute = 15 seconds

Now, the time difference between 6:15 p.m. and 6:18 p.m. is = 3 minutes

So, One whole minute has 60 seconds, which means 

= 60 / 15 = 4 quarters 

So, 3 minutes will have = 4 × 3 = 12 quarter minutes.

1 hour = 4 quarter hours 

60 seconds = 1 minute

120 seconds = 120/60 = 2 minutes

∴ The time 120 seconds after 16:30 hours = 16:00 + 2

⇒ 16:32 hours

The time from 12 midnight to 12 noon is the forenoon or the 1st half of the day, denoted as a.m.

No. of hours of work per day = 6 hours 30 minutes

No. of hours of work for 5 days = 6 hours 30 minutes × 5

= 30 hours 150 minutes

60 minutes = 1 hour
∴ 150 minutes = 2 hours 30 minutes
∴ 30 hours 150 minutes = 30 hours + 2 hours 30 minutes

= 32 hours 30 minutes
