Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Only one video is displayed between M2 and M5
1. Video M2 is displayed in class 1.
| Class | Video |
| 5 | |
| 4 | |
| 3 | |
| 2 | |
| 1 | M2 |
2. Video M1 is displayed in the class just below the class where M5 is displayed.
3. Video M5 is displayed at an even numbered class.
Hence, video M5 must be in class 4th.
| Class | Video |
| 5 | |
| 4 | M5 |
| 3 | M1 |
| 2 | |
| 1 | M2 |
4. Video M4 is not displayed in an even numbered class.
Hence, M4 must be displayed in class 5.
So remaining video M3 is for class 2.
| Class | Video |
| 5 |
M4 |
| 4 |
M5 |
| 3 |
M1 |
| 2 |
M3 |
| 1 |
M2 |
Option 1: Only one video is displayed after M3 (Correct)
Option 2: Only two videos are displayed after M1 (Correct)
Option 4: M1 is displayed between M3 and M5 (Correct)
Hence, option 3 i.e. Only one video is displayed between M2 and M5 is not correct.
