After each duty, the doctor gets an off for 3 days, including the day heis relieved from duty. For example,if Amir has a duty on Monday, his next duty will now fall on Friday and this rotation goes on.

1. Amir
2. Sahil
3. Vaibhav
4. Gaurav

Solution

Share

Number of days between 10th July to 26th September = 78
The cycle of doctors gets repeated every 4 days. 
Hence, Gaurav will be back on duty on 24th September (as it is 76 days from 10th July and 76 is a multiple of 4)
Hence, Sahil will be on duty on 26th September.
