if you find it difficult, there is another way to solve it.
First add untill you don't find 7hrs
=6 hrs 45 mins+15 mins
Now, only 25 mins left!
=3 hrs+15 mins +45 mins

The difference between 7 hours 25 min and 3 hrs 45 min is :a)4 hrs 15 ...
The difference between 7 hours 25 min and 3 hrs 45 min is 3 hrs 40 min.
Explanation:
To find the difference between two durations, we subtract the smaller duration from the larger duration.
Given:
Duration 1 = 7 hours 25 min
Duration 2 = 3 hrs 45 min
Step 1:
First, we need to convert the durations into a common unit. In this case, we will convert both durations to minutes.
Duration 1:
7 hours = 7 x 60 = 420 minutes
25 min = 25 minutes
So, Duration 1 = 420 minutes + 25 minutes = 445 minutes
Duration 2:
3 hours = 3 x 60 = 180 minutes
45 min = 45 minutes
So, Duration 2 = 180 minutes + 45 minutes = 225 minutes
Step 2:
Now, we can find the difference between the two durations by subtracting Duration 2 from Duration 1.
Difference = Duration 1 - Duration 2
= 445 minutes - 225 minutes
= 220 minutes
Step 3:
Finally, we need to convert the difference back to hours and minutes.
220 minutes = 3 hours 40 minutes
Therefore, the difference between 7 hours 25 min and 3 hrs 45 min is 3 hrs 40 min.
So, the correct answer is option C) 3 hrs 40 min.
