In a hospital there is a consumption of 1350 litres of milk for 70 patients for 30 days. How many patients will consume 1710 litres of milk in 28 days.
The answer would be 95.
By chain rule , More patients consume more milk and more patients require less days to consume milk. So,x(No. of patients)=(70*1710*30)/(1350*28)=95(Answer)
70 patients x 30 days=2100 patient/days 1350/2100=9/14 litres/patient/day 1710/28=61 61 / (9/14)= about 95 patients
