D. 12 h 45 min

Answer

To find the duration of the journey of the train from Hyderabad to Bengaluru, we will calculate the time from the departure to the arrival.

### Step-by-Step Solution:

1. **Identify the Departure and Arrival Times:**
- Departure: 13:15 (1:15 PM) on Friday
- Arrival: 07:30 (7:30 AM) on Saturday

2. **Calculate the Time from Departure to Midnight:**
- From 13:15 (1:15 PM) to 24:00 (midnight) on Friday:
- 24:00 - 13:15 = 10 hours and 45 minutes
- So, the time from 1:15 PM to midnight is **10 hours and 45 minutes**.

3. **Calculate the Time from Midnight to Arrival:**
- From 00:00 (midnight) to 07:30 (7:30 AM) on Saturday:
- This is simply 7 hours and 30 minutes.
- So, the time from midnight to 7:30 AM is **7 hours and 30 minutes**.

4. **Add the Two Time Intervals Together:**
- Now, we add the two durations calculated:
- 10 hours 45 minutes (from Friday to midnight)
- 7 hours 30 minutes (from midnight to Saturday)
- To add these:
- Hours: 10 + 7 = 17 hours
- Minutes: 45 + 30 = 75 minutes
- Since 75 minutes is more than 60 minutes, we convert 75 minutes into hours:
- 75 minutes = 1 hour and 15 minutes
- Therefore, we add this to the hours:
- 17 hours + 1 hour = 18 hours
- Remaining minutes = 15 minutes

5. **Final Duration of the Journey:**
- The total duration of the journey is **18 hours and 15 minutes**.

### Final Answer:
The duration of the journey was **18 hours and 15 minutes**.
