In June 2021, if the difference between the number of male Covid-19 positive patients and female Covid-19 positive patients was 72. What was the number of admitted patient in June 2021?

It is given that the ratio of number of male covid positive patients to female covid patients = 9:5

Let the number of male covid positive patients be '$$9x$$' and female covid positive patients be $$5x$$

The difference between number of male and female covid positive patients = 72

$$9x-5x=72$$

$$4x=72$$

$$x=18$$

Hence the total number of covid positive patients = $$9x+5x=14x=14\times\ 18=252$$

From the table, the total number of covid positive patients is 42% of the total admitted patients.

Let the total number of admitted patients be $$y$$

Then,  the total number of covid positive patients = 42% of $$y$$

$$0.42y=252$$

$$y=600\ $$

Therefore the total number of admitted patients is 600.

Option (D) is correct.
