Question

Two hours later would be as long until midnight. What time is it now?
A. 18:30
B. 20:00
C. 21:00
D. 22:00

Answer 1

Hint: Here, we have been given that it is 2 hours from midnight and we need to find the current time. For this, we will first have to know what time is midnight. Midnight is characterized by the end of a day. Hence, the time at midnight is given as 24:00. Then we will write 2 hours as 2:00 hours and subtract this time from the time at midnight. As a result, we will get the current time.

Complete step by step answer:
Now, we have been given that after 2 hours, it will be midnight. We know that according to the 24 hour format, midnight means the end of the day. So it is 24:00 at midnight.
Now, before 2 hours of midnight, the time will be given by the 24:00 hours minus 2 hours.
We also know that 2 hours are written as 2:00 hours also. Hence, the time before 2 hours of midnight is given as:
$\begin{align}
  & 24:00-2:00 \\
 & \therefore 22:00 \\
\end{align}$
Thus, the time right now is 22:00.

So, the correct answer is “Option D”.

Note: Here, we have been given all the options in 24 hour format so we have calculated the answer in that format. If we would have been given even at least one of the options in 12 hour format, we would have had to calculate the answer in that format too. So we should know that according to that format, the time at midnight is 12am and before 12 am, the time is in pm starting from 12pm which is 12:00 hours in the 24 hour format.
