Question: How many flights take off between Flight J and the flight scheduled to land in Lucknow?

Accepted Answer

**Solution:**

1. From the given conditions and arrangement, the flights and their slots are as follows:

| Time   | Flight | Destination  |
|--------|--------|--------------|
| 4:00pm | I      | Indore       |
| 4:05pm | -      | -            |
| 4:10pm | O      | Chandigarh   |
| 4:15pm | N      | Kolkata      |
| 4:20pm | -      | -            |
| 4:25pm | S      | Pune         |
| 4:30pm | G      | Surat        |
| 4:35pm | T      | Jaipur       |
| 4:40pm | B      | Goa          |
| 4:45pm | L      | Delhi        |
| 4:50pm | D      | Mysore       |
| 4:55pm | -      | -            |
| 5:00pm | K      | Lucknow      |

2. Flight J is placed before Flight L but not immediately before. Since L is at 4:45 pm, J must be at 4:35 pm or earlier. Given J takes off six slots before Surat (which is at 4:30 pm), J is at 4:00 pm.

3. Flight J is at 4:00 pm, and Flight K (landing in Lucknow) is at 5:00 pm.

4. The number of flights taking off between Flight J (4:00 pm) and Flight K (5:00 pm) is the count of flights in the slots between these two times.

5. The slots between 4:00 pm and 5:00 pm are at 4:05, 4:10, 4:15, 4:20, 4:25, 4:30, 4:35, 4:40, 4:45, 4:50, and 4:55.

6. Among these, the flights taking off are O (4:10), N (4:15), S (4:25), G (4:30), T (4:35), B (4:40), L (4:45), and D (4:50).

7. Counting these, there are 7 flights between J and K.
