Question

In a hospital, there were many patients of COVID-19. 2/5 th of them were on ventilator, 1/2 of the remaining were using only oxygen cylinders and 600 were in isolation ward.
1) How many patients required ventilator?
2) How many patients were in need of only oxygen cylinder?​

Answer 1

Answer:

1) Patients on ventilators = 240

2) Patients on o2 cylinders = 300

Step-by-step explanation:

Number of patients = 600

Fraction of patients on ventilators = 2/5

Patients on ventilators = (2/5)(600) = 120×2 = 240

Fraction of patients on o2 cylinders = 1/2

Patients on o2 cylinders = (1/2)(600) = 300

Answer 2

Assuming x as total number of patients.
