Answer: Option D
Explanation:
When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart.
At 7 o’clock, they are 25 min. spaces apart.
Minute hand will have to gain only 5 min. spaces.
55 min. spaces are gained in 60 min.
| 5 min. spaces are gained in | 60 | x 5 | min | = 5 | 5 | min. | |
| 55 | 11 |
| Required time = 5 | 5 | min. past 7. |
| 11 |
