Answer:
100 days
Step-by-step explanation:
The doctor treated 2000 patients
He worked for 5 hrs a day and,
Spent 15 minutes per patient
1 patient takes 15 minutes
In 5 hrs he treats;
300/15 = 20 patients
In one day he treats 20 patients
We are to find the number of days he treats 2000 patients.
Cross multiplying gives;
2000/20 = 100 days
