Question

What is the time:
$4$ hours $10$ minutes before $12$ noon.

Answer 1

Hint: We are asked to find the time before $12$ noon. So, first we will subtract the hours part of the given time i.e., $4$ hours and then from that we will subtract the minutes’ part i.e., $10$ minutes to find the final time.

Complete step-by-step answer:
We have to find the time $4$ hours $10$ minutes before $12$ noon.
We know,
$12$ noon in time form is written as $12:00\;PM$.
Here, the ‘before’ word tells us that the time has already passed , so we need to subtract the time.
If we subtract $4$ hours from $12:00\;PM$, the time we get is $8:00\;AM$ .
And subtracting further $10$ minutes , the time we get is $7:50\;AM$ .
Therefore, the time $4$ hours $10$ minutes before $12$ noon is $7:50\;AM$.
So, the correct answer is “$7:50\;AM$”.

Note: When the ‘before’ word is used, we need to subtract the time from the time given in question and when the ‘after’ word is used we need to add the time to the time given in question. The sequence for subtracting or adding time is first the hours, second minutes and then seconds but the reverse order is not applicable. If we subtract or add seconds first then minutes and then hours , the answer might get wrong or can get very complicated.
