• B. a. 11:15:00; b. 14:30, 4:50, 19:58, 3:15
• C. a. 11:15:00; b. 14:30, 4:50, 17:58, 3:15
• D. a. 11:05:50; b. 2:30, 4:50, 7:58, 3:15

Answer 1

The correct option is B a. 11:15:00; b. 14:30, 4:50, 19:58, 3:15

a. From the given clock figure, we can see that the hour hand is moving towards 11 and the minute hand is moving towards 3.

To write time,
Hours = 11
Minutes = 3 x 5 = 15 minutes
The seconds hand is moving towards 12, which means it is exactly zero position. There is no advancement in seconds.

Time writing format = Hours:Minutes:Seconds

Time in the clock = 11:15:00

b. In a 24-hour clock, we have to convert the timings of p.m. only. The a.m. timings will also be the same in 24-the hour clock.

1) 2:30 p.m.
We will simply add 12 to the hours in a 24-hour clock during conversion from the 12 hours format.

12 + 2 = 14
Then, 24-hour format = 14:30
Similarly we can convert all time in 24 - hour format.

2) 4:50 a.m. (it will be the same)

3) 7:58 p.m. (12 + 7 = 19) Time in 24-hour clock = 19:58

4) 3:15 a.m. (It will be the same)
