After each duty, the doctor gets an off for 3 days, including the day heis relieved from duty.

Question 82

# If on $$14^{th}$$ February 2020, Sahil was on duty, then who did the maximum number of duties in that month?1. Amir2. Sahil3. Vaibhav4. Gaurav

Solution

If Sahil is on duty on 14th Feb, then Amir was on duty on 13th Feb and Gaurav was on duty on 12th Feb and so on. From this, we can deduce that starting from Feb 1, the order of duty is: Amir-Sahil-Vaibhav-Gaurav.

From this we can see that everyone will have served for equal days till 28 Feb and then on 29th Feb (2020 being leap year), Amir will serve one more day and hence, Amir serves maximum time.
